CS-IGF-1C hydrogel increased hP-MSCs retention in vivo. a The fate of hP-MSCs after transplantation was tracked by BLI. Mice received 1 × 106 hP-MSCs alone, hP-MSCs with CS, or hP-MSCs with CS-IGF-1C hydrogel. b Quantitative analysis of BLI signals demonstrated that cell survival was improved by the application of CS-IGF-1C hydrogel. Data are expressed as mean ± SEM. *P < 0.05 versus hP-MSCs; #P < 0.05 versus hP-MSCs co-transplanted with CS hydrogel
