Abstract:
AIM: To investigate the differentiation from human mesenchymal stem cells(hMSC) into neuron-like cells by the increase in intracellular cyclic AMP. METHODS: hMSC were separated from human marrow with Ficoll-Paque reagent and expanded in culture medium. hMSC were induced to differentiate into neurons with Forskolin and 3-isobutyl-1-methyl-xanthine (IBMX). Neuron-specific enolase(NSE), neurofilament(NF), glial fibrillary acaidic protein(GFAP) were detected by immunohistochemistry. RESULTS: hMSC were expanded as undifferentiated cells in culture for more than 10 passages. Forskolin/IBMX can induce hMSC to exhibit a neuronal phenotype, expressing NSE and NF-M in 5 hours. But the neuron-like cells didn't express the glial astrocyte marker GFAP. CONCLUSION: hMSC can be induced to differentiate into neurons by increase in the intracellular cAMP.
