An injectable, self‐healing hydrogel (≈1.5 kPa) is developed for healing nerve‐system deficits. Neurosphere‐like progenitors proliferate in the hydrogel and differentiate into neuron‐like cells. In the zebrafish injury model, the central nervous system function is partially rescued by injection of t...
