Comparison between Injectable Platelet-Rich Fibrin and Platelet-Rich Plasma in Ameliorating UVA-Induced Photoaging in Human Dermal Fibroblasts via the Activation of TGF-β/Smad Signaling Pathway

Researchers compared the anti-photoaging effects of injectable platelet-rich fibrin in UVA-irradiated human dermal fibroblasts with those of platelet-rich plasma by examining cell proliferation, migration, and apoptosis, ROS generation, matrix metalloproteinase and collagen I levels.
