  • EXPERIMENTAL INVESTIGATION ON CHARACTERISTICS OF C3H1OT1/2 CELL INDUCED DIFFERENTIATIONINTO NEURONLIKE CELLS

    Objective To explore the method that can inducethe mesenchymal stem cells (MSCs) to differentiate into the neuronlike cells in vitro.Methods The neuron-like cells were isolated froman SD rat (age, 3 months; weight, 200 g). They underwent a primary culture; theinduced liquid supernatant was collected, and was identified by the cell immunohistochemistry. The C3H1OT1/2 cells were cultured, as an MSCs model, and they were induced into differentiation by β-mercaptoethanol (Group A) and by the liquid supernatant of the neuron-like primary cells (Group B), respectively. The cells were cultured without any induction were used as a control (Group C). Immunohistochemistrywas used to identify the type of the cells. Results The result of the immunochemistry showed that the cells undergoing the primary culture expressed the neurofilament protein (NF) and the neuronspecific enolase (NSE), and they were neuron-like cells. β-mercaptoethanol could induce the C3H1OT1/2 cells toexpress NF and NSE at 2 h, and the expression intensity increased at 5 h. The liquid supernatant of the primarily-cultured neuron-like cells could induce theC3H1OT1/2 cells to express NF and NSE at 1 d, but the expression intensity induced by the liquid supernatant was weaker than that induced by β-mercaptoethanol. The positivity rate and the intensity expression of NSE were higher than those of NF. Conclusion MSCs can differentiate into the neuron-like cells by β-mercaptoethanol and the microenvironment humoral factor, which can pave the way for a further study of the differentiation of MSCs and the effectof the differentiation on the brain trauma repair. 
