Differentiation of neural stem cells in three-dimensional growth factor-immobilized chitosan hydrogel scaffolds

The adult central nervous system (CNS) contains adult neural stem/progenitor cells (NSPCs) that possess the ability to differentiate into the primary cell types found in the CNS and to regenerate lost or damaged tissue. The ability to specifically and spatially control differentiation is vital to enable cell-based CNS regenerative strategies. Here we describe the development of a protein-biomaterial system that allows rapid, stable and …
