From: Near-infrared-emitting nanoparticles activate collagen synthesis via TGFβ signaling
Activation of the TGF-β1 signaling pathway and the upregulation of collagen biosynthesis genes. Measurement of collagen biosynthetic genes in HaCaT keratinocytes after (a) Ag2S (left) and Li-doped Ag2S (right) treatment at various concentrations for 24 h. In the same way, (b) Ag2S (left) and Li-doped Ag2S (right) NPs were used to treat HDF cells. The data are expressed as the mean ± SEM. ∗p < 0.05 vs 0 (control).
