Unveiling Therapeutic Potential: A Systematic Review of Photobiomodulation Therapy and Biological Dressings for Diabetic Foot Ulcers.

Introduction: Diabetes poses a global health challenge, giving rise to various complications, including diabetic foot ulcers (DFUs). DFUs, marked by ischemic ulcers susceptible to infection and amputation, underscore the urgency for innovative treatments. This study investigated the impact of photobiomodulation therapy (PBT) and autologous platelet gel (APG) on DFUs recovery. Methods: We systematically searched Web of Science, EMBASE, MEDLINE, Cochrane Library, Scopus, and Google Scholar (2015-2023) by using pertinent terms like "photobiomodulation therapy," "low level light therapy," and "platelet gel." After meticulous data extraction and review, 57 articles were chosen and categorized. Among these, three randomized controlled trials involving 186 participants were selected for APG analysis. Results: Findings demonstrate that APG application carries minimal risk and offers promising improvements in healing time, grade, pain reduction, and granulation tissue formation. Similarly, diverse PBT modalities involving distinct probes and wavelengths exhibit the potential to enhance tissue perfusion, expedite healing, and impede wound progression, reducing the need for invasive interventions. Conclusion: PBT and APG emerge as valuable tools to augment wound healing, mitigate inflammation, and avert amputation, representing compelling therapeutic options for DFUs.

Treatment of superficial and deep partial width second degree burn's wound with allogeneic cord blood platelet gel.

BACKGROUND: Burns are caused by a variety of mechanisms, including flames, hot liquids, metallurgy, chemicals, electric current, and ionizing and non-ionizing radiation. The most significant burn wound management involves complete repair and regeneration as soon as possible while minimizing infection, contraction, and scarring in the damaged tissue area. Some factors such as delivery of nutrients, growth factors, and oxygen are essential to promote and stimulate the wound healing progress in the burns area. When these factors are not provided, the burn wound undergoes a physiological crisis. The use of growth factors is a promising approach to overcoming this limitation. Umbilical cord blood platelet concentrates are a rich natural source of growth factors. METHODS: This clinical trial used growth factors released from the lysis of umbilical cord blood platelet concentrates that have a key role in promoting re-epithelization and regeneration of damaged tissues by forming a fibrin network. This study evaluated the effectiveness of allogeneic cord blood platelet gel topical dressing in a group of patients diagnosed with superficial and deep partial thickness (second-degree) burn wounds. Clinical outcomes were compared between the intervention group and a control group of patients with superficial second-degree burn wounds who received the standard routine treatment including paraffin gauze wound dressing and silver sulfadiazine ointment. RESULTS: The study's results showed that the increased rate of recovery and tissue granulation completely promoted to wound healing and burn wound closure, decreased the recovery time, and reduced inflammation and scars caused by burn injuries. However, the use of cord blood platelet gel topical dressing is not currently a routine treatment method in patients suffering from burn wounds. However, the study's results showed that allogenic cord blood platelet gel could be used to treat superficial and deep second-degree burns as a routine treatment. It was also shown that allogenic cord blood platelet gel topical dressing could be a candidate for autograft or after autograft skin transplantation surgery (in donor and recipient sites) instead of skin surgery in some patients. CONCLUSION: Allogeneic topical wound dressing provides an effective treatment that offers a faster rate of epithelialization and healing of wounds and also decreases patients' scar and inflammation level as well as the length of recovery time. This, finally, leads to better burn wound management and the improved quality of burn wound treatment.

Comparison of the efficacy of autologous platelet gel and medical chitosan in the prevention of recurrence of intrauterine adhesions after transcervical resection of adhesion: a prospective, randomized, controlled trial.

PURPOSE: Intrauterine adhesion (IUAs) in women is a debatable topic and there is no clear consensus in its management and treatment strategies. Previous treatment measures have limitations which necessitates to consider effective measures for prevention of recurrence of IUAs. Hence, the aim of this study to explore the efficacy and safety of intrauterine infusion of autologous platelet gel (APG) and medical chitosan in preventing recurrence of IUAs in females after transcervical resection of adhesion (TCRA). METHODS: A prospective, randomized controlled trial was conducted among 80 patients presented with moderate to severe IUAs. Patients were randomized into two groups, APG group (n = 40) and medical chitosan group (n = 40). All patients were injected with either APG or medical chitosan after TCRA. RESULTS: The postoperative recurrence rate of adhesions in APG group was significantly lower than those in medical chitosan group (21% vs 49%). The median AFS score during the second-look hysteroscopy was significantly lower in APG group than in medical chitosan group (P = 0.008). The median AFS score reduction after TCRA surgery was significantly higher in APG group than in medical chitosan group (median, 95% CI 7.000, 6.0 to 8.3 vs. 6.000, 5.0 to 7.0, P = 0.004). Subgroup analysis of platelet concentration (1000 as cut-off value) into high- and low-dose subgroups reported no significant correlation existed between APG and baseline characteristics, recurrence rate and postoperative AFS reduction score except for previous intrauterine operation (P < 0.05). CONCLUSION: Thus, after TCRA, intrauterine injections of APG provides better efficacy and safety compared with intrauterine injections of medical chitosan in preventing recurrence of intrauterine adhesions.

Allogeneic platelet gel therapy for refractory abdominal wound healing: A preliminary study.

BACKGROUND: Refractory abdominal wounds are commonly complicated by surgical site infections, which prolong hospital stays and increase medical costs. There is little clinical data on the use of allogeneic platelet gel (PG) therapy for refractory infected wounds. OBJECTIVES: This study aimed to evaluate the efficacy and safety of allogeneic PGs in the treatment of refractory abdominal wounds. MATERIAL AND METHODS: A prospective single-center study was performed in a national abdominal trauma referral center between June 2019 and June 2021. A total of 11 patients with refractory abdominal wounds were treated with allogeneic PGs after the failure of standard medical treatments. The PGs were derived from platelets collected from healthy donors using apheresis, and each PG was tested for platelet count, transfusion-related diseases, aerobic and anaerobic bacteria, and growth factor concentration. Clinical efficacy was evaluated by assessing the wound surface and observing the condition of the wound, including wound area and percentage of granulation. RESULTS: The median age of the patients was 37 years (1st quartile, 3rd quartile (Q1, Q3): 31-55 years), median (Q1, Q3) hemoglobin level was 95 g/L (78-120 g/L) and median (Q1, Q3) serum albumin level was 39.9 g/L (34.9-42.7 g/L). The PG platelet count was 976.5 ±174.9×109/L. Results of transfusion-associated contagion tests for aerobic and anaerobic bacteria were negative. Growth factor contents (pg/mL) were: for transforming growth factor beta 1 (TGF-ß1); 2542.39 ±430.60, for platelet-derived growth factor BB (PDGF-BB); 23230.03 ±4236.14 and FOR vascular endothelial growth factor (VEGF); 91.41 ±23.31. The rate of wound healing was 100%, and the median (Q1, Q3) healing time was 30 days (18-40 days). The follow-up period was 5-27 months, during which no recurrence of the wounds was found. CONCLUSIONS: The present study demonstrated that allogeneic PGs are a safe and effective treatment for refractory abdominal wounds.

Carboxymethyl Cellulose-Based Hydrogel Film Combined with Umbilical Cord Blood Platelet gel as an Innovative Tool for Chronic Wound Management: A Pilot Clinical Study.

Treatment of chronic leg ulcers remains a major challenge and it is a substantial financial burden on individuals, families, caregivers, and health care system. There is increasing evidence on using of autologous Platelet-rich-plasma in wound repair but limited clinical data are available on the efficacy and safety of the use of umbilical cord blood platelet gel (CBPG). In our pilot study, for the first time, we aimed to evaluated the safety and efficacy of the use of umbilical CBPG combined with a hydrogel dressing in 10 patients with chronic venous ulcers (VU). The protocol consisted of application of umbilical cord blood platelet-rich plasma (PRP) combined with a Carboxymethyl cellulose (CMC)-based hydrogel dressing once a week for 4 weeks. The 80% of patients after 4 weeks of treatment had a significantly decrease in wound size. Moreover, we obtained an improvement in terms of mean Wound Bed Score (WBS), numeric rating scale (NRS) value and the EQ-5D index score. This pilot study showed that the topically therapeutic administration of umbilical CBPG associated with a CMC-based hydrogel dressing has the potential to accelerate the healing of chronic lesions without adverse reaction. However, additional studies with larger sample size and longer follow-up periods are required to confirm our findings.

Impressive Nasal Septum Regeneration after Cord Blood Platelet Gel (CBPG) in Extreme Premature Neonate with Non-Invasive Ventilation: A Case Report.

BACKGROUND: We evaluated the efficacy of Cord Blood Platelet Gel (CBPG) in the regenerative reconstruction of the nasal septal tissue of a preterm infant undergoing non-invasive ventilation. METHODS: A CBPC treatment was used to enhance the regeneration of the nasal septum of a premature patient in an experimental way, evaluating the efficacy described in the literature (selective bibliographic search in PubMed) of the use of blood products for non-transfusion purposes. RESULTS: A partial but satisfactory regeneration of the patient's nasal septum was observed. Using the free NIH Image J online software, we were able to calculate the regenerated surface (about 83% of the destroyed cartilage). CONCLUSIONS: The use of platelet gel has been a promising alternative to surgical treatment in patients with severe damage to the nasal septum.

Combination of platelet-rich plasma and platelet gel in treatment of resistance androgenic alopecia: A case series study.

BACKGROUND: Androgenic alopecia is a common genetic disorder that characterized by progressive hair follicles and hair atrophy. Despite all available therapeutic techniques, there is low patient satisfaction rate. It seems finding new treatment options for androgenic alopecia is necessary. In the past decade, platelet-rich plasma (PRP), an autologous collection of concentrated platelets with hemostatic and tissue repairing effects, has received developing attention for androgenetic alopecia treatment as a valuable therapeutic technique. METHODS: In this study, 8 patients suffering from resistance androgenic alopecia were enrolled. The PRP and platelet gel were prepared, and a total volume of 10 cc of the combination of PRP and platelet gel were injected in the scalp androgen-related areas using 23-gauge syringe. The treatment was performed one month and 3 months after first injection (three times). The hair pull test was done before treatment. The outcome was evaluated 3, 6, and 9 months after treatment by hair pull test, dermoscopy, photography, and patient's satisfaction. RESULTS: A significant reduction in hair loss was observed before and after treatment. Hair count (density) increased from average number of 72 (hair/cm2 ) to 210 hair/cm2 ). Also, the hair diameter was significantly increased before and after treatment for all patients (p < 0.05). After the treatment, the pull test was significantly decreased in 8 patients (p < 0.05). CONCLUSION: This study supports the combination therapy of PRP and platelet gel for resistance androgenic alopecia treatment. This technique is an uncomplicated, feasible, and cost-effective treatment option for resistance androgenic alopecia, with high patient satisfaction.

Autologous platelet gel improves outcomes in tubularized incised plate repair of hypospadias.

BACKGROUND: hypospadias is one of the most widespread male congenital anomalies, occurring in 1:250 to 1:300 live births. Several repair techniques have been developing to improve the outcomes. PURPOSE: a randomized prospective controlled study was adopted to evaluate effectiveness of autologous platelet gel in healing promotion and improving the outcomes of hypospadias repair. METHODS: thirty children who aged between 6 months and 12 years were recruited and subdivided into two groups; group A had tubularized incised plate (TIP) repair with autologous platelet gel application and group B had TIP repair without autologous platelet gel. RESULTS: there was no significant difference in duration of operation between both groups. All patients in groups A and B had slit-like meatus shape in the distal glans. While all those of group A had one urine stream, yet only 11 of group B had one. There were complications that happened exclusively in group B such as spray stream (27%) and fistula (20%). Whereas other complications occurred insignificantly more in group B than in A including meatal stenosis (53 versus 27%), glans dehiscence, (20 versus 7%), bleeding (33 versus 13%), infection (33 versus 27%), edema (27% versus13), respectively. The incidence of skin necrosis was equal in both groups. CONCLUSION: autologous platelet gel usage in TIP hypospadias repair can be a reliable technique to promote wound healing, and to limit of postoperative surgical complications.

Cord Blood Platelet Gel as a Treatment of Occipital Pressure Injuries in Newborns: Report of Two Cases.

BACKGROUND: A Pressure Ulcer (PU) is a severe event and could create discomfort to newborns. In newborns, one of mostly stricken location by PU is occipital area. Recent studies have highlighted that Cord Blood Platelet Gel (CBPG) might be a better alternative compared to traditional treatment. We report two cases of occipital PU treated with CBPG. CASE REPORT: Two male infants showing occipital PU were treated with standard local treatment, but no improvement was observed. After parental informed consent was obtained, CBPG application on PU was performed every 48 h. In these two cases of PU, a fast improvement in healing was observed since the first application of CBPG. The PU healed resulted in a scar after 53 and 50 days (Case 1 and Case 2, respectively) from development. No complications or infections were reported. CONCLUSIONS: CBPG contains many angiogenetic and growth factors, these characteristics make it indicated in treating soft tissue injuries. It would seem to be safe and an effective treatment of neonatal PUs reducing the time of the healing and the hospitalization and the infectious risks. Further studies are needed to evaluate long term aesthetic and functional results of PU treated with CBPG.

The role of cord blood platelet gel in the management of a diabetic foot with tendon exposure.

Diabetic foot infection is frequent in diabetic patients and is due to neuropathy, trauma or peripheral arterial disease. The presence of an abscess requires urgent drainage and specific antibiotic therapy. Patients with critical limb ischemia need revascularization and, subsequently the intervention of a plastic surgeon is often required in cases of exposure of tendons and ligaments. During the COVID-19 pandemic, a patient was refered to our department with an abscess on the dorsum of the left foot. After urgent drainage with tendon exposure, he started specific antibiotic therapy and underwent tibial vessels angioplasty. After infection healing cord blood platelet gel was applied, accelerating the healing process, with injection of its liquid part into the exposed tendons, thus retaining the vital functions of the tendons.

Selection Criteria of Cord Blood Units for Platelet Gel Production: Proposed Directions from Hellenic Cord Blood Bank. Comment on Mallis et al. Short Term Results of Fibrin Gel Obtained from Cord Blood Units: A Preliminary in Vitro Study. Bioengineering 2019, 6, 66.

This article provides additional knowledge for cord blood platelet gel (CBPG) production. Recently, it has been shown that CBPG exerts beneficial properties in wound healing applications. CBPG is produced after a two-step centrifugation process, following the addition of calcium gluconate. Clinical-grade CBPG can be produced in public cord blood banks, worldwide. However, standardization of the CBPG production process must be established in order to reduce discrepancies that occurred due to different platelet gel preparations. This article aims to provide an update regarding the selection criteria of cord blood units (CBUs), and to provide evidence for the improvement of the CBPG production process. (Comment on "Short Term Results of Fibrin Gel Obtained from Cord Blood Units: A Preliminary in Vitro Study" Bioengineering 2019, 6, 66).

Current applications of platelet gels in wound healing-A review.

Human platelets play important roles in several physiologic and pathologic processes. Platelet concentrates are activated with thrombin or calcium, resulting in a viscous coagulum (platelet gel [PG]), composed of 95% platelets at least. PG is increasingly used for the treatment of a variety of soft and hard tissue defects, most notably in the management of chronic non-healing wounds. During wound healing, platelets not only play a critical role in primary hemostasis and thrombosis, but also release growth factors and cytokines to promote tissue regeneration, enhance collagen synthesis, and trigger an immune response. This review addresses a variety of aspects relevant to the functions of well-known platelet growth factors, animal and clinical studies of PG in the last decade, and different sources of platelets for PG. PG is used for non-healing chronic wounds, such as oral ulcerations related to epidermolysis bullosa and chronic graft-versus-host disease, for those, the traditional treatment effect is poor. PG maybe provide a new therapeutic direction for these diseases. Nevertheless, some uncertainty is present, the number of clinical studies is not enough. Hence, randomized controlled trials are still required to study the potential of the use of PG in the near future.

Recycling Apparent Waste Into Biologicals: The Case of Umbilical Cord Blood in Italy and Spain.

Most public cord blood banking programs are currently facing financial difficulties due to a progressive decline in the number of cord blood transplants performed worldwide and to a high discard rate of the donated units caused by progressively increasing thresholds of the stem cell dose required to perform safe and effective hemopoietic cord blood transplants. Recycling a proportion of unused cord blood units to prepare novel cord blood components obtained with minimal manipulation (platelets, plasma, red blood cells) and to develop more technologically complex products regulated in the US as Cellular and Gene Therapy Products and in Europe as Advanced Therapy Medicinal Products [e.g. virus-specific T cells (VST), natural killer (NK) cells, induced pluripotent stem cells (iPSCs) is a promising strategy to increase the therapeutic value and reduce the financial deficits of public cord blood banking. Based on encouraging preliminary evidences reported in the literature, additional laboratory studies, large multicenter clinical trials and international regulatory harmonization are necessary to achieve these important goals. This article describes organizational, methodological and regulatory advancements developed in Italy and Spain to promote the clinical use of cord blood platelets, plasma and red blood cells.

Application of allogeneic platelet gel in surgical operation for giant aortic aneurysms, one case / 中国输血杂志

【Objective】 To explore the effect of allogeneic platelet gel on hemostasis and repair of vascular anastomoses and wounds in patients with giant aortic aneurysms during surgery. 【Methods】 One adult dose of allogeneic platelets, applied as platelet rich plasma (PRP), was prepared as platelet gel (PG) (about 220 mL) for spraying or smearing at the vascular anastomosis and thoracic wound during the surgery of giant aortic aneurysms. 【Results】 The gel formation was presented about 30 seconds after spraying or smearing with PG on the anastomotic and wound surface. The hemostatic effect is good, with less postoperative drainage fluid from pericardium and mediastinum than usual, and the ICU stay was 4 days. 【Conclusion】 Allogeneic platelets as a source of PRP to prepare PG may be applied to obtain the clotting and healing during surgical operation.

Use of cord blood platelet gel to enhance healing of deep surgical site dehiscences after peripheral bypass.

Surgical site dehiscence after lower limb revascularization through bypass represents a serious postoperative complication, especially in diabetic and obese patients, with subsequent risk of early graft failure, infection, sepsis, hemorrhage, major amputation and sometimes death. To prevent bypass exposure and subsequent complications, physicians recur to reoperation, antibiotic therapy, advanced dressing and vacuum-assisted closure therapy. To improve the process of wound healing, cord blood platelet gel can be used to fill deep and large wounds. Growth factors released from platelets in the cord blood platelet gel stimulate the process of healing and allow patients to be followed up in Outpatient Surgery, thus reducing hospital stay and costs, while providing excellent results.

Leucocyte-Rich Platelet-Rich Plasma Enhances Fibroblast and Extracellular Matrix Activity: Implications in Wound Healing.

BACKGROUND: Platelet-rich plasma (PRP) is an autologous blood product that contains a high concentration of platelets and leucocytes, which are fundamental fibroblast proliferation agents. Literature has emerged that offers contradictory findings about leucocytes within PRP. Herein, we elucidated the effects of highly concentrated leucocytes and platelets on human fibroblasts. METHODS: Leucocyte-rich, PRP (LR-PRP) and leucocyte-poor, platelet-poor plasma (LP-PPP) were compared to identify their effects on human fibroblasts, including cell proliferation, wound healing and extracellular matrix and adhesion molecule gene expressions. RESULTS: The LR-PRP exhibited 1422.00 ± 317.21 × 103 platelets/µL and 16.36 ± 2.08 × 103 white blood cells/µL whilst the LP-PPP demonstrated lower concentrations of 55.33 ± 10.13 × 103 platelets/µL and 0.8 ± 0.02 × 103 white blood cells/µL. LR-PRP enhanced fibroblast cell proliferation and cell migration, and demonstrated either upregulation or down-regulation gene expression profile of the extracellular matrix and adhesion molecules. CONCLUSION: LR-PRP has a continuous stimulatory anabolic and ergogenic effect on human fibroblast cells.

Umbilical cord blood: Current uses for transfusion and regenerative medicine.

The past 20 years of experience with umbilical cord blood transplantation have demonstrated that cord blood is effective in the treatment of a spectrum of diseases, including hematological malignancies, bone marrow failure, hemoglobinopathies, and inborn errors of metabolism. However, only a few number of umbilical cord blood units collected have a cell content adequate for an allogenic hematopoietic stem cell transplantation. In the meanwhile, there is an increasing interest in exploiting cord blood derivatives in different fields. In this review, we will summarize the most recent updates on clinical applications of umbilical cord blood platelet derivatives for regenerative medicine, and we will revise the literature concerning the use of umbilical cord blood for autologous or allogeneic transfusion purposes. The methodological aspect and the biological characteristics of these products also will be discussed.

Evaluation of safety and efficacy of autologous topical platelet gel vs platelet rich plasma injection in the treatment of venous leg ulcers: A randomized case control study.

Various management options were tried for Chronic venous leg ulcers (VLUs) with no satisfactory results. Platelet-rich plasma (PRP) is promising in enhancing chronic wound healing by releasing various growth factors. We evaluated the safety and efficacy of topical platelet gel (PG) vs PRP injection in treatment of venous leg ulcers. 20 patients were treated with topical PG (group I), 20 patients received PRP injection (group II), and 20 patients were treated with saline dressing and compression as controls (group III) weekly for 6 weeks. Ulcer improvement was evaluated by pressure ulcer scale for healing (PUSH). Histopathological evaluation and immunohistochemical staining using anti-CD34 were performed before and after treatment. There was significant improvement in PUSH score in group (I) and (II) compared to group (III; P value: .001). However, there was no statistically significant difference in improvement between group I and II (P value = .83). However, topical PG was more effective in diabetics and PRP was more effective in long standing fibrosed ulcers. Histopathology showed reduction of the inflammatory cells infiltrates and well-formed granulation tissue with no difference in immunostaining. So, both topical PG and PRP injection were effective, low cost, and safe procedures in enhancing healing of chronic VLUs.

Evaluation of platelet-rich plasma gel as an angiogenesis-inducing agent in canine advancement skin flaps / Avaliação do gel de plasma rico em plaquetas como agente indutor da angiogênese em flapes cutâneos de avanço em cães

This work aimed to evaluate the effect of platelet-rich plasma (PRP) on advancement skin flaps in dogs regarding improvement of vascularization, with focus on increasing its viable area, since there are reports that it is a potential angiogenesis stimulator. The experimental group was composed of eight adult bitches, in which two advancement skin flaps were made in the ventral abdominal region. No product was applied in the control flap (CF), while PRP was used in the contralateral flap, called treated flap (TF). The areas were clinically evaluated every two days until the 7th postoperative day regarding skin color and presence of necrosis. At 10 days, both flaps were removed and submitted to histological examination and blood vessel morphometry. The vessels counted in each group were statistically analyzed by the F-test at 1% probability. Results showed no significant difference in macroscopic changes in the wound, or CF and TF vascularization, thus suggesting that PRP gel did not improve advancement skin flap angiogenesis in bitches under the experimental conditions in which this research was developed.(AU)

Objetivou-se com o presente artigo avaliar a ação angiogênica do gel de plasma rico em plaquetas (PRP) em flapes cutâneos de avanço em animais da espécie canina, visando aumentar a viabilidade da pele após o procedimento, uma vez que existem relatos de que o produto é um potente estimulador da angiogênese. O grupo experimental foi composto por oito cadelas adultas, onde foram confeccionados dois flapes de avanço (de padrão subdérmico) na região abdominal ventral. Em um dos flapes, considerado controle (FC) não foi aplicado nenhum produto, enquanto que no flape contralateral, denominado tratado (FT), foi usado o gel de PRP. As áreas foram macroscopicamente avaliadas a cada dois dias até o 7º dia de pós-operatório em relação à coloração da pele e presença de área de necrose, e com 10 dias ambos os flapes foram coletados por biópsia e submetidos ao exame histológico e morfometria dos vasos sanguíneos. Os vasos contados em cada grupo foram estatisticamente analisados pelo teste de F ao nível de 1% de probabilidades. Os resultados demonstraram que não houve diferença significativa nas alterações macroscópicas das feridas e na morfometria vascular dos FC e FT, sugerindo dessa maneira que dentro das condições experimentais nas quais a pesquisa foi executada, que o gel de PRP não incrementou a angiogênese de flapes de avanço em cadelas.(AU)

Effect of Cord Blood Platelet Gel on wound healing capacity of human Mesenchymal Stromal Cells.

BACKGROUND: Wound healing is a dynamic process, involving the recruitment of growth factors, cytokines, chemokines and cellular populations. Recently, the Cord Blood Platelet Gel (CBPG) has been applied successfully in wound closure and tissue regeneration. Moreover, its proper combination with stem cell populations such as Mesenchymal Stromal Cells (MSCs) may positively improve the wound healing process. Based on the above data, this study aimed to the evaluation of wound healing capacity of MSCs combined with CBPG under in vitro conditions. METHODS: Initially, CBPG was developed from Cord Blood Units (CBUs). The determination of wound healing ability of MSCs was performed using the scratch wound assay. In addition, the morphological features, immunophenotypical characteristics and differentiation capacity of MSCs were evaluated. RESULTS: Scratch wound assay results showed, that CBPG could positively stimulate the MSCs migration. Moreover, MSCs cultured in presence of CBPG were characterized by elongated shape and improved stemness properties as it was indicated by flow cytometric analysis and differentiation process. CONCLUSION: These results clearly showed the beneficial effect of CBPG in combination with MSCs in wound healing. The proper combination of CBPG with stem cells strategy may enhance the healing process in patients with skin erosions.
