Laminin (925-933)(CDPGYIGSR), is the sequence of Laminin on the B1 chain. YIGSR is active in promoting the adhesion of a variety of epithelial cells[1]. Laminin binds to colagen IV, heparan sulfate proteoglycan, and nidogen-entactin,and it mediates cellular interactions with this ma-trix[2].
A laminin-derived synthetic peptide, Cys-Asp-Pro-Gly-Tyr-Ile-Gly-Ser-Arg-NH2 (CDPGYIGSR-H2), containing an active site for cell binding inhibited both angiogenesis and solid tumor growth[3].
In vitro, at concentrations of 100 and 300 µg/ml, Laminin (925-933) can stimulate the attachment of HT-1080 and CHO cells to culture plates[2].
In vitro, the oligopeptide domain Laminin (925-933) covalently linked to an agarose gel as a bioartificial 3D substrate successfully supports neurite outgrowth from dorsal root ganglia (DRG)[2]. In vitro, a 78% reduction in cell attachment was observed on films containing Laminin (925-933) in the cell plating medium[4].
In vivo experiments revealed the capability of a Laminin (925-933)-derivatized gel to enhance nerve regeneration in a transected rat dorsal root model compared to an underivatized gel, a Laminin (925-933) gel, and saline-filled nerve guidance channels[3].
