Effect of GSE4-nanoparticles on the development of bleomycin-induced skin fibrosis. C3H mice received daily subcutaneous injections of bleomycin, and were also injected with either scramble (Bleo + Scr) or GSE4 (Bleo + GSE4) nanoparticles every other day for 4 weeks. Control mice were daily injected with saline. A Representative image of Masson’s stained skin biopsy for each group. B Fibrosis was measured as the fold increase in the collagen Masson stained area adjusted to the normal area (saline group). Quantification of mRNA expression by quantitative RT-PCR of Acta2 (C) and Ctgf (D). *p < 0.05, **P < 0.01, ***p < 0.001 (Median and IQR, Mann-Whitney test). Graphic shows data of 3 independent experiments with 10 mice per group. Bar 50 μm
