Conceptual illustration of PDGF-mimicking peptide hydrogel promotes wound healing. PDGF-mimicking peptide hydrogelators contain assembling motif, linker, and PDGFR binding domain. PDGFR binding domain is residues 153-162 displayed in orange, which binds and activates PDGF receptor. Designed peptide can self-assemble to form nanofibrils/hydrogel, which exhibits injectable properties and promotes wound healing
