Figure 2 CD26 promotes cell proliferation, migration, and collagen biosynthesis in vitro. (A) Cell proliferation was remarkably increased in CD26+ WFs (CCK-8 viability assay). (B) The expressions levels of CD26 and Col1 were significantly increased in CD26+ WFs. Representative images of WB are shown. (C) The concentrations of CD26 and Col1 in the supernatant were determined by ELISA (n=5). * P<0.05 vs CD26+ NF group, ** P<0.01 vs CD26+ NF group. (D) Significant enhancement of cell migration in CD26+ WFs as gauged by wound healing assay and quantification (n=5). * P<0.05 vs CD26− NF group, ** P<0.01 vs CD26− WF group. (E) Significant enhancement of cell migration in CD26+ WFs as gauged by transwell assay and its quantification (n=5). ** P<0.01 vs CD26− NF/WF group. Scale bar: 100 μm, t test.
