Effect of LMAPs on the expression of procollagen type I in fibroblasts. LMAP treatment had no effect on fibroblast viability (A). LMAPs increased the secreted protein and cellular protein levels of type I collagen in UVR-induced fibroblasts (B). Data are presented as mean ± S.D. n = 3; # p < 0.05 vs. untreated control, * p < 0.05. LMAP: low-molecular-weight anionic peptide; UVR: UVA 2 J/cm2 + UVB 15 mJ/cm2.
