摘要： Umbilical cord mesenchymal stem cel s were isolated by a double enzyme digestion method. The third passage of umbilical cord mesenchymal stem cel s was induced with heparin and/or basic fi-broblast growth factor. Results confirmed that cel morphology did not change after induction with basic fibroblast growth factor alone. However, neuronal morphology was visible, and microtu-bule-associated protein-2 expression and acetylcholine levels increased fol owing induction with heparin alone or heparin combined with basic fibroblast growth factor. Hb9 and choline acetyl-transferase expression was high fol owing inductive with heparin combined with basic fibroblast growth factor. Results indicate that the inductive effect of basic fibroblast growth factor alone was not obvious. Heparin combined with basic fibroblast growth factor noticeably promoted the differen-tiation of umbilical cord mesenchymal stem cel s into motor neuron-like cel s. Simultaneously, um-bilical cord mesenchymal stem cel s could secrete acetylcholine.
