ABSTRACT
BACKGROUND:
Studies have shown that mesenchymal stem cells can participate in the repair of wound injury caused by diabetes, but the high glucose environment obviously inhibits the function of mesenchymal stem cells and the effect of transplantation.OBJECTIVE:
To observe the effect of conditioned medium of bone marrow mesenchymal stem cells intervened by rosiglitazone on the proliferation and migration of endothelial progenitor cells in high glucose environment.METHODS:
(1) The bone marrow mesenchymal stem cells from the logarithmic growth period were cultured in three groups. The normal group was cultured with alpha-MEM medium containing 10% fetal bovine serum. The high glucose group was cultured with alpha-MEM medium containing 10% fetal bovine serum and 25 mmol/L glucose. The rosiglitazone group was cultured with alpha-MEM medium containing 10% fetal bovine serum, 25 mmol/L glucose and 10 μmol/L rosiglitazone. After 48 hours of culture, the culture supernatant was extracted as conditioned medium. The levels of vascular endothelial growth factor and matrix cell derived factor 1 in conditioned medium were detected by ELISA. (2) The endothelial progenitor cells from the logarithmic growth period were divided into three groups. The control group was cultured with the EGM-2 MV medium containing 10% fetal bovine serum. The model group was cultured with the EGM-2 MV medium containing 10% fetal bovine serum, 30 mmol/L glucose and conditioned medium of the high glucose group. The experimental group was cultured with EGM-2 MV medium containing 10% fetal bovine serum, 30 mmol/L glucose and conditioned medium of the rosiglitazone group. After 24 hours of culture, the ability of cell proliferation and migration was detected. RESULTS ANDCONCLUSION:
(1) The levels of vascular endothelial growth factor and matrix cell derived factor 1 in the conditioned medium of high glucose group were significantly lower than that of the normal group (P < 0.05). The levels of vascular endothelial growth factor and matrix cell derived factor 1 in the conditioned medium of the rosiglitazone group were significantly higher than in the high glucose group (P < 0.05). (2) The proliferation and migration ability of endothelial progenitor cells in the model group was lower than that in the control group (P < 0.05). The proliferation and migration ability of endothelial progenitor cells in the experimental group was higher than that in the model group (P < 0.05). (3) It is suggested that the conditioned medium of rosiglitazone intervened bone marrow mesenchymal stem cells can promote the proliferation and migration of endothelial progenitor cells.
