چکیده انگلیسی
The purpose of this study was to prepare a monolayer of neural stem/precursor cells (NSPCs) for neural tissue engineering applications. Two components present in serum, fibronectin and epidermal growth factor (EGF) were added into DMEM/F12 medium (termed medium B) to examine the effect of the migration-, proliferation- and differentiation-promoting potential on the cultured NSPCs, isolated from embryonic rat cerebral cortex. Compared with the serum effect, medium B also permitted neurosphere attachment onto the substrate surface and cell migration out of neurospheres extensively, but enhanced more extensive cell division and slowed down NSPC differentiation to generate a confluent NSPC monolayer. It was found the medium B-treated NSPCs possessed the capability to form typical neurospheres or to undergo differentiation into neuron-related cell types on various biomaterial surfaces. Therefore, we proposed a two-stage process for wound healing or nerve conduit preparation. Extensive NSPC division and MAP2-positive neuron differentiation were manipulated in NSPCs cultured in the medium B followed by the neuronal differentiation-favorable medium. These results should be useful for controlling the proliferation and differentiation of NSPCs on various biomaterials and conduits in neuroscience research.
