Velvet antler polypeptide is able to induce differentiation of neural stem cells towards neurons in vitro

To investigate the neural differentiation capacity of water extraction of velvet antler. Methods Velvet antler (Cervus Nippon Temminck) polypeptide (VAP) was used to differentiate neural stem cells (NSCs) towards neurons in the study. Firstly, we obtain the polypeptides of VAP by water extraction. Secondly, we observed the morphology, assayed the factors in the media by enzyme-linked immunosorbent assay, and detected the special neural molecules by immunofluorescence staining. NSCs were cultured on the cell climbing film. After neuronal differentiation, differentiated NSCs were mounted for immunocytochemistry with immunofluorescence technique. Results The differentiating cells look like neuron, some special factors, such as Glial cell line-derived neurotrophic factor, nerve growth factor, in the media can be detected while differentiated neuron -like cells can express the special neural molecules. Conclusion Differentiation of NSCs towards neurons can be induced by velvet antler polypeptide.
