Abstract:

BACKGROUND: Mesenchymal stem cells can differentiate into nerve cells by chemical induction or co-culture method, but whether mesenchymal stem cells co-cultured with Schwann cells differentiate into neuronal-like cells or Schwann-like cells is still controversial.

OBJECTIVE: To explore the inductive role of Schwann cells derived from rats in the differentiation of human umbilical cord mesenchymal stem cells.
METHODS: Cocultures of human umbilical cord mesenchymal stem cells (1×109/L) and Schwann cells (1×109/L) from neonatal rats were performed using transwell culture dishes. After 2 weeks of cocultures, morphology of the cultured human umbilical cord mesenchymal stem cells was observed, and the phenotypic changes of cells were also detected with immumocytochemistry techniques.
RESULTS AND CONCLUSION: After 2 weeks of cocultures, some differentiated cells showed neuron-like morphology, and expressed nestin, NF-200 and β-III-tubulin, but did not express Schwann cell special marker S100 and oligodendrocytes special marker MAB1580. These findings indicate that human umbilical cord mesenchymal stem cells can transdifferentiate into neuronal-like cells by cocultures with rat’s Schwann cells.
