TRANSCRIÇÃO
The overall goal of this experiment is to prepare either unmodified or oligopeptide or extra-cellular matrix-grafted polyvinyl alcohol-co-itaconic acid hydrogels with the optimal elasticity for culturing and passaging stem cells. This method can h

A protocol is presented to prepare polyvinyl alcohol-co-itaconic acid hydrogels with varying stiffness, which were grafted with and without oligopeptides, to investigate the effect of the stiffness of biomaterials on the differentiation and proliferation of stem cells. The stiffness of the hydrogels was controlled by the crosslinking time.
