The PL@GM hydrogel can promote the viability and migration of HDFs. (A) Live and dead stain assay for GM and PL@GM hydrogel. Scale bar = 200 μm. (B) Wound healing assay of HDFs with different concentration gradient PL treatment for 24 h. Scale bar = 200 μm. (C) Quantitative analysis for live and dead stains and cell viability is represented as the total ratio of live cells to live and dead cells. (D) CCK8 assay shows HDFs viability under the treatment of PL@GM for 24 h. (E) Quantitative analysis for wound healing assay and HDFs migration is represented as the ratio of the scratched wound area of HDFs with PL@GM treatment (24 h) to the area without treatment. All the above data are expressed as mean ± SD. *p < 0.05 or **p < 0.01 vs. Control group by one-way ANOVA followed by LSD multiple comparison. We repeated the experiments three times to ensure the accuracy of the experiments.
