“…In addition, this hydrogel matrix is beneficial because bioactive agents, such as RGD, can be incorporated into this matrix to interact with the cells released from the degradable microbeads. 61 Although soluble RGD peptide is related with cell death, 31,62 immobilized RGD peptide is important for cell adhesion, [63][64][65] migration, 19,66 and differentiation. 37,55 In the present study, when macropores were created within the matrix with the degradation of microbeads, cells were released into the macroporous matrix, thus allowing the RGDmodified AM to help enhance myogenic differentiation.…”
