Abstract:

BACKGROUND: Currently, bone marrow mesenchymal stem cells can differentiate into nerve cells via many approaches. Different methods for inducing bone marrow mesenchymal stem cells differentiating into nerve cells have different ratios.
OBJECTIVE: To investigate the difference between chemical method and co-culture method to induce the differentiation of rat bone marrow mesenchymal stem cells into nerve cells.
METHODS: Rat bone marrow mesenchymal stem cells were isolated and purified using whole bone marrow culture method, and then randomly divided into two groups: chemical group, β-mercaptoethanol was added; co-culture group, co-cultured in a Transwell chamber.
RESULTS AND CONCLUSION: Visible protrusions from induced cells showed radiation growth at 1 week of induced culture, and neuron-specific enolase staining was positive at 2 weeks of culture. Star-like structure of nerve cells was visible in the co-culture group within 4-5 days of culture, and then more protrusions formed. Meanwhile, the positive rate of neuron-specific enolase was (70.82±2.46)%. After 6-7 days of culture, neuron-like cells formed and were interconnected in the chemical group; while, the positive rate of neuron-specific enolase was (52.37±1.83)%. These findings suggest that cell microenvironment plays a leading role in the differentiation of bone marrow mesenchymal stem cells into nerve cells, and chemical induction method is inferior to the co-culture method.
