α1β1 Ligand

GFOGER peptide is an artificially synthesized collagen-mimetic sequence. GFOGER peptide acts as a ligand for α2β1, α11β1 and α1β1 integrins, thereby supporting integrin-mediated cell adhesion to collagen. GFOGER peptide triggers signaling pathways mediated by the α2β1 integrin receptor and upregulates osteoblast differentiation. GFOGER peptide accelerates and enhances bone formation at sites of refractory femoral defects. GFOGER peptide can be passively adsorbed onto polymer scaffolds for cell-free/growth factor-free bone formation. GFOGER peptide is used in biomaterials such as hydrogels and 3D bioinks for tissue engineering research including bone formation.

Collagen (bovine skin) is a three-dimensional cell culture matrix and morphoregulator extracted from bovine skin, which binds to integrins (such as α1β1, α2β1, α11β1) and discoidin domain receptors (DDR1 and DDR2). Collagen (bovine skin) can be reconstituted into a three-dimensional fibrous network to mimic the in vivo tissue environment. It can not only be modified through cross-linking or concentration adjustment, but also interact with fibronectin to enhance matrix-associated cellular activities. Collagen (bovine skin) mediates the proliferation, aggregation, durotactic migration and differentiation of fibroblasts, regulates the synthesis, remodeling and contraction of extracellular matrix, and modulates the expression, activation of MMP as well as cell apoptosis, etc. Collagen (bovine skin) can be used in studies related to the mechanisms of cancer occurrence and development.
