Abstract

Here, we report a unique method to quantify the effects of in vivo-like extracellular matrix (ECM) for guiding differentiation of neural stem cells (NSCs) in three-dimensional (3D) microenvironments using quantitative real-time polymerase chain reaction (qRT-PCR). We successfully monitored and quantified differentiation of NSCs in small volume ECMs and found that differentiation of NSCs, especially those differentiating towards neuronal and oligodendrocytic lineages, is significantly enhanced by 3D microenvironments reconstituted in the microfluidic channels.
