Abstract：Objectives? To investigate the effects of ketamine on the differentiation of bone marrow mesenchymal stem cells (BMSCs) into neural cells in vitro. Methods? SFP-grade rats were sacrificed, and the rat BMSCs were isolated and purified, and then induced with different concentrations of ketamine: 0 μmol/L (control group), 1 μmol/L (experiment group 1), and 10 μmol/L (experiment group 2). Cell proliferation were detected by MTT assay, apoptosis were detected by flow cytometry, and microtubule-associated protein 2 (MAP2) and glial fibrillary acidic protein (GFAP) expression levels were detected by Western blot. Results? The cell survival rates, the relative expression of MAP2 and GFAP protein in the experiment group 2 and the experiment group 1 were significantly higher than those in the control group, and those in the experimental group 2 were significantly higher those in the experimental group 1, at 24 h and 48 h after treatment (P＜0.05). The apoptosis rates of the experiment group 2 and the experiment group 1 were significantly lower than that of the control group (P＜0.05), and that of the experimental group 2 were also significantly lower than that of the experimental group 1 (P＜ 0.05). Conclusions? Ketamine can increase the MAP2 and GFAP proteins of BMSCs, promote the proliferation of BMSCs and inhibit cell apoptosis, thus promote their differentiation into neural cells in vitro.
