Osteoblast-Adhesive Peptide (Lys-Arg-Ser-Arg) acetate is an adhesion peptide utilized as a dental or orthopedic biomaterial to facilitate and strengthen the attachment of osteoblasts (anchor-dependent cells). Osteoblast adhesion is mediated through integrin and proteoglycan mechanisms. This peptide acetate may exhibit specificity for osteoblasts or bone cells in the proteoglycan-mediated adhesion process.
