Abstract
Abstract Polypeptides derived from domain VI of the amino terminal globule of the A chain of laminin and having sequences of at least about 5 amino acids, and which exhibit cell adhesion and cell spreading capacity are described. Medical devices such as prosthetic implants, percutaneous devices and cell culture substrates coated with a composition including the described polypeptides are also provided.
