First Claim
1. A cell adhesion promoting (CAP) peptide-modified polymer composition useful for promoting cell attachment or growth, comprising a polymer surface comprising a cell adhesion resistant (CAR) material to which one or more peptides are covalently bound, forming a peptide-modified CAP surface, which peptides/surface promote attachment of cells, which cells substantially do not attach to said CAR surface in the absence of said peptides, wherein each of said one or more peptides comprises:
- (a) one or more peptide sequences selected from the group consisting of SEQ ID NO;
2 (EFIKY), SEQ ID NO;
3 (EEEKV), SEQ ID NO;
4 (GHK), SEQ ID NO;

12 (AKKMV), SEQ ID NO;
14 (AFIPV), SEQ ID NO;
15 (KKMYY), and SEQ ID NO;
16 (AIKKK);
(b) a chemically or recombinantly prepared peptide multimer that includes at least two repeats of any one or a combination of SEQ ID NOs;
2–
4, 6, 8, 10–
12, and 14–
16;
or(c) a cell adhesion promoting variant of any one or more of SEQ ID NOs;
2–
4, 6, 8, 10–

Abstract
The present invention relates to cell adhesion promoting (“CAP”) peptide combinations that promote cell attachment or cell adhesion to culture surfaces that are otherwise cell adhesion resistant “CAR”. The invention provides combination of peptides that, when covalently coupled to a CAR layer such as hyaluronic acid that has been created on a polystyrene surface, promote cell attachment, growth differentiation, and execution of other desired cellular functions in culture.
