RZ10-RGD hydrogels were cytocompatible. (A) LIVE/DEAD images of NIH/3T3 fibroblasts cultured for 24 h on TCP or RZ10-RGD hydrogels. Live cells were stained green, and dead cells were stained red. Scale bars represent 100 μm. (B) High cell viability (>95%) was observed on both TCP and RZ10-RGD. No significant difference in cell viability was observed between the two groups (unpaired two sample t-test, p > 0.05).
