Abstract

We developed the photocrosslinkable hydrogel microwell arrays for uniform-sized neurosphere-mediated motoneuron differentiation. Neural stem cells (NSCs) were obtained from embryonic cerebral cortex and spinal cord. To generate uniform-sized neurospheres in a homogeneous manner, the dissociated cells were cultured in the hydrogel microwell arrays for 3 days. Uniform-sized neurospheres harvested from microwell arrays were replated into laminin-coated substrate. In parallel, uniform-sized neurospheres cultured in microwell arrays were encapsulated by photocrosslinkable gelatin methacrylate hydrogels in a three-dimensional manner. We demonstrated the effect of hydrogel microwell sizes (e.g., 50, 100, 150 μm in diameter) on motoneuron differentiation, showing that the largest uniform-sized neurospheres derived from embryonic spinal cord efficiently differentiated into motoneurons. Therefore, this hydrogel microwell array could be a powerful array to regulate the uniform-sized neurosphere-mediated motoneuron differentiation.
