A F-actin cytoskeleton staining of NSCs cultured on the control, GelMA and GelMA/ECM scaffolds (blue arrows represent the linear direction). B Live/dead staining of NSCs cultured on the control, GelMA, and GelMA/ECM scaffolds. C The proliferation of NSCs cultured on the control, GelMA, and GelMA/ECM scaffolds. Control: tissue cell plates. n = 3.
