Abstract:
:Hair follicle stem cells (HFSCs) are able to differentiate into neurons and glial cells. Distinct microRNAs (miRNAs) regulate the proliferation and differentiation of HFSCs. However, the exact role of miR-124 in the neural differentiation of HFSCs has not been elucidated. HFSCs were isolated from mouse whisker follicles. miR-9, let-7b, and miR-124, Ptbp1 , and Sox9 expression levels were detected by real-time polymerase chain reaction (RT-PCR). The influence of miR-124 transfection was evaluated using immunostaining. We demonstrated that miR-124 and let-7b expression levels were significantly increased after the neural differentiation. Sox9 and Ptbp1 were identified as the target of miR-124 in the HFSCs. During neural differentiation and miR-124 mimicking, Ptbp1 and Sox9 levels were decreased. Moreover, the miR-124 overexpression increased MAP2 (58.43 ± 11.26) and NeuN (48.34 ± 11.15) proteins expression. The results demonstrated that miR-124 may promote the differentiation of HFSCs into neuronal cells by targeting Sox9 and Ptbp1.
