Peptides for enhanced cell attachment and growth
First Claim
1. A cell culture vessel for culturing adherent cells, said vessel comprising a polymer surface, a hyaluronic acid (HA) layer bonded to said polymer surface, and one or more peptides covalently bound to the HA layer, wherein said peptides promote adherence of cells that do not adhere to the HA layer in the absence of said peptides, and 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;
6 (KKLVY), SEQ ID NO;
8 (AFAFK), SEQ ID NO;
10 (KMLIY), SEQ ID NO;
11 (KSYYY), 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, 10-12, and 14-16, said variant having a conservative substitution of a single amino acid residue, wherein said variant has the ability to promote cell attachment or growth.

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.
