DIFFERENTIATION OF MESENCHYMAL STEM CELLS INTO NEURON- LIKE CELLS WITH LIGUSTRAZIN HYDROCHLORIDE / 解剖学报

ABSTRACT

Objective To investigate the differentiation of mesenchymal stem cells(rMSCs) of young rat into neuron-like cells with Ligustrazin hydrochloride. Methods rMSCs were separated from femurs marrow flushed out with DMEM(low glucose) by using a needle and syringe, then planted in plastic culture flask. Through expanded to 5 passages, rMSCs were induced to differentiate into neuron-like cells with Ligustrazin hydrochloride. Anti-neurofilament(NF-M), nestin, neuron-specific enolase(NSE), MAP-2,GAP-43 and glial fibrillary acidic protein(GFAP) antibodies were detected by immunohistochemistry. Results rMSCs were comprised a single phenotypic population and displayed a fibroblast-like morphology after 5 passage in culture. With 10*!?g/L bFGF pre-induce for 24*!h, then the medium was replaced with induction medium containing Ligustrazin hydrochloride. The induced-rMSCs exhibited neuronal morphological characteristics from the first half an hour to 5*!h. The neuron-like cells expressed NF-M, NSE, MAP-2,GAP-43 and nestin positive, but didn't express glial astrocyte marker GFAP.Conclusion rMSCs can be induced to differentiate into neuron like cells with Ligustrazin hydrochloride in vitro.
