摘要
Introduction: The aim of the study was to explore an effective method to induce adipose-derived stem cells (ADSCs) to differentiate into Schwannlike cells in vitro. Material and methods: Reagents were applied in two different ways (Dezawa inducing method and modified inducing method) in which inducers including beta-mercaptoethanol (beta-ME), all-trans-retinoic acid (ATRA), type I collagenase, forskolin, heregulin, basic fibroblast growth factor (BFGF) and brain-derived neurotrophic factor (BDNF) were used in different ways to induce ADSCs of rats to differentiate into Schwann-like cells. After induction, the cell morphologic characteristics and the cellular immunohistochemical staining positive rate of anti-S100 and anti-GFAP (glial fibrillary acidic protein) antibodies and the gray value of immunocytochemical dye with anti-S100 and anti-GFAP antibodies and cell activity measured by the MTT method were compared with each other to evaluate the induction effects. Results: Both methods can induce differentiation of ADSCs of rats into Schwann-like cells, but the cellular morphology of the modified method was more similar to Schwann cells than that of the Dezawa inducing method, there was a higher cellular immunohistochemical staining positive rate and staining grey value in immunocytochemical dye with anti-S100 and antiGFAP antibodies, and less damage in the cell activity of the modified inducing method than that of the Dezawa inducing method. Conclusions: The effect of the modified method to induce ADSCs to differentiate into Schwann-like cells in vitro is superior to that of the Dezawa inducing method.
