Fig. 3From: Successive Release of Tissue Inhibitors of Metalloproteinase-1 Through Graphene Oxide-Based Delivery System Can Promote Skin RegenerationThe effect of TIMP-1-GO on rat fibroblast cell proliferation and viability. a The viability of fibroblasts cultured in different groups show no significant differences in different time points (p > 0.05). b The cell cycle of fibroblast was not significantly different than that of cells grown in different groups (p > 0.05). c The cell apoptosis of fibroblast was not significantly different than that of cells grown in different groups (p > 0.05)Back to article page
