Abstract

Objective To investigate the role of Mash1 in differentiation of anterior subventricular zone (SVZa) neural stem cells to gamma-aminobutyric acid (GABA) neurons. Methods The neural stem cells derived from SVZa of postnatal Kunming mouse aged 0 day (P0) were separated and cultured in vitro. The rate of GABA neurons in the differentiated cel

ls of neural stem cells of SVZa induced by different plasmids of Mash1 was detected by cell counting and flow cytometry (FCM). Results Double digestions verified the successful construction of Mash1-GFP

+

and Mash1-GFP

-

. The rate of GABA neuron in the group of sense Mash1 was higher than that of blank control group while the rate of GABA neuron in the group of antisense Mash1 was lower than that of blank control group. Conclusion pEGFP-Mash1

-

and pEGFP-Mash1

+

plasmids have been successfully constructed. Mash1 can promote the GABA neuronal differentiation of the neural stem cells of SVZa.
