Abstract:
Objective Comparison of induction time on the proliferation of induced adipose-derived stem cells (ADSC) to differentiate into Schwann-like cells (iSC).Methods From March,2017 to October,2018,ADSCs were isolated from inguinal adipose tissue of healthy adult female SD rats.Flow cytometry was performed to detect ADSC positive markers CD29,CD90 and negative marker CD45.iSC induction medium was used to culture ADSC.S-100 and GFAP were detected by immunofluorescence staining to confirm that ADSC had differentiated into iSC.Morphological changes of cells were observed by inverted microscope on day 1st,4th,7th,10th,13rd,16th and 19th after induction.MTS assay was used to evaluate cell proliferation ability.Tunel staining was applied to assess cell apoptosis.Results Both S100 and GFAP were expressed in iSC.On day 7th,the cell proliferation rate was significantly slower than that before induction (A value was 0.330±0.020 vs.0.400±0.004,P<0.05).It was negatively correlated with induction time.On day 19th,the proliferation rate of iSC was lower than 50% of the proliferation rate before induction (A value was 0.016±0.003 vs.0.400±0.004,P<0.05).Apoptosis of iSC was more obvious than ADSC at the same time point.Conclusion The proliferation ability of ADSC-induced iSC is optimal within 7 days after induction.
