Fig. 9: The relationship between the self-healing properties of hydrogels and the functional recovery.

A Relation between the metabolic rate of cells in hydrogels and the self-healing properties of hydrogels observed in this study. B Relation between the in vivo neural regeneration and the self-healing properties of hydrogels observed in this study. The symbol “x” indicates the data points of the extent (%) of functional recovery plotted against the minimal strain (%) for structure destruction (an index of self-healing) of hydrogel. C Relation between the in vivo neural regeneration and the metabolic rate of cells in hydrogels observed in this study
