Abstract:
A composition which can bind heparin and promote cellular adhesion and neurite outgrowth is provided which consists essentially of a polypeptide of the formula:
tyr-glu-lys-pro-gly-ser-pro-pro-arg-glu-val-val-pro-arg-pro-arg-pro-gly-val
lys-asn-asn-gln-lys-ser-glu-pro-leu-ile-gly-arg-lys-lys-thr-asp-glu-leu,
lys-asn-asn-gln-lys-ser-glu-pro-leu-ile-gly-arg-lys-lys-thr,
leu-ile-gly-arg-lys-lys-thr,
tyr-arg-val-arg-val-thr-pro-lys-glu-lys-thr-gly-pro-met-lys-glu,
ser-pro-pro-arg-arg-ala-arg-val-thr,
trp-gln-pro-pro-arg-ala-arg-ile,
or mixtures thereof. Medical devices such as prosthetic implants, percutaneous devices and cell culture substrates coated with the polypeptide composition are also provided. Cell culture substrates provided can be made of a synthetic resin and in the form of a bead, microporous fiber or well of a microtiter plate.
