ABSTRACT
Fluoxetine is a common antidepressant which selectively inhibits serotonin reuptake at synaptic level. Some research findings have proposed the effect this drug on neurogenesis, neuronal survival as well as proliferation of the neural progenitor cells. Endometrium is a part of uterus which harbors mesenchymal stem cells. This source of stem cells can be differentiated into neural cells which may potentially be used in treating many diseases. Given the above, this study was designed to assess the effect of fluoxetine on neural cells differentiation from endometrial stem cells. Endometrial stem cells obtained from stem cell banking were cultured in Dulbecco's modified eagle's medium [DMED] containing fetal bovine serum [FBS] in the presence of Retinoic Acid, fluoxetine and Retinoic Acid+fluoxetine for 10 days. To assess the differentiation of endometrial stem cells into neural-like cells, we used immunocytochemistry and RT-PCR. The viability of cells was assessed using the trypan blue test. Data analysis revealed that 61% of endometrial stem cells differentiated to neural-like cells. Moreover, the biopotency of neural-like cells on fluoxetine treatment was more pronounced across differentiation days. Based on our findings, fluoxetine was shown to be a suitable inducer for the differentiation of neural-like cells from endometrial stem cells
ABSTRACT
Due to increasing clinical demand for adipose tissue, a suitable cell for reconstructive adipose tissue constructs is needed. In this study, we investigated the ability of Human Endometrial-derived stem cells [EnSCs] as a new source of mesenchymal stem cells to differentiate into adipocytes. EnSCs are the abundant and easy available source with no immunological response, for cell replacement therapy. Single-cell suspensions of EnSCs were obtained from endometrial tissues from 10 women experiencing normal menstrual cycles, and were cultured at clonal density [10 cells/cm[2]] or limiting dilution. Endometrial mesenchymal stem cell markers were examined flow cytometry. These cells were treated with adipogenicinducing medium for 28 days. The adipogenic differentiation of the EnSC was assessed by cellular morphology and further confirmed by Oil Red O staining and RTPCR. The BM-MSC differentiated into adipocytes in the presence of adipogenic stimuli for 3 weeks. The flow cytometric analysis showed that the cells were positive for CD90, CD105, CD146 and were negative for CD31, CD34.We showed that the key adipocytes marker PPARa was expressed in mRNA level after 28 days post treatment [PT]. According to our finding, it can be concluded that EnSCs represent a useful in vitro model for human adipogenesis, and provide opportunities to study the stages prior to commitment to the adipocyte lineage
