Addition of a functional bioactive peptide can induce beneficial properties for wound healing. It can facilitate the adhesion and survival of stem cells, and promote the differentiation of stem cells to cardiomyocytes, as in the case of addition of RGDSP peptide . Alternatively, it can be used to prepare cultures of human umbilical cord mesenchymal stem cells (hUC-MSCs) and cultured astrocytes for treatment of traumatic brain injury, as in the case of covalently bonded RGIDKRHWNSQ peptide .
