T1D ASCs enhance the migration, proliferation, and α-SMA and collagen I/III expression of fibroblasts in vitro. A Representative images of “wounds” in the scratch assay before and 24 h after co-culture with T1D or control ASCs. B Migration rates of fibroblasts. C Representative images of mice fibroblasts before and 5 days after co-cultured with T1D or control ASCs. D Cell numbers of fibroblasts co-cultured with T1D ASCs or ASCs for 5 days. E Gene expression of α-SMA, collagen I, and collagen III. Bars = 200 μm. Each bar represents the mean ± SD of three independent experiments. *p < 0.05, **p < 0.01, Student’s t test
