Abstract
- This study aimed to investigate the potentials of ex vivo expansion and pluridifferentiation of cryopreserved adult human bone marrow mesenchymal stem cells (hMSCs) into adipocytes and neurocytes. Cryopreserved hMSCs were resuscitated and cultured for 15 passages, and then induced to adipocytes and neurocytes with corresponding induction medium. The induced cells were observed for morphological properties and expression of triglyceride or neuron-specific enolase and nestin was detected. The result showed that the resuscitated cells cultured in induction medium consisting of dexamethasone, 3-isobutyl-1-methylxanthine, indomethacin and insulin-like growth factor I (IGF-I) showed adipogenesis, and lipid vacuole accumulation was detectable after 21days. The resuscitated hMSCs were also induced into neurocytes and expressed nestin and neuron-specific enolase (NSE), which are special surface markers associated with neural cells at different stages. This study suggested that resuscitated hMSCs should still be a population of pluripotential cells and should be accessible for establishing an abundant hMSC reservoir for further experiment and treatment of various clinical diseases.
