Synthetic surfaces capable of supporting culture of cells in culture, particularly cells that will be used therapeutically, are disclosed. The synthetic cell culture surfaces have a functionalized peptide, a peptide that has been functionalized to contain a polymerization moiety, and optionally a spacer, grafted to a hydrophilic polymeric base material. Methods of making the surfaces and methods of using the surfaces are also disclosed. 1. A functionalized peptide comprising:{'sub': m', 'p', 'ap, 'a composition of the formula R—S—C'}wherein R is a polymerization moiety selected from the group consisting of acrylate, methacrylate, acrylamide, methyacrylamide, maleimide, fumarate and epoxide and combinations, and m is an integer equal to or greater than 1; and,{'sub': p', '2', 'm2', '3', 'n, 'wherein Sis a spacer moiety wherein the spacer moiety comprises polyethylene oxide or polypropylene oxide having the formula (O—CHCHR′)where R′ is H or CHand m2 is an integer from 1 to 20, or Xaawherein Xaa is independently any amino acid and n is an integer from 0 to 20, or a combination; and'}{'sub': 'ap', 'wherein Cis a peptide comprising a cell adhesive sequence.'}2. The functionalized peptide of wherein Scomprises a Lys or Arg amino acid.3. The functionalized peptide of wherein the cell adhesive peptide (C) comprises the sequence: KGGGQKCIVQTTSWSQCSKS (SEQ ID NO:1); GGGQKCIVQTTSWSQCSKS(SEQ ID NO:2); KYGLALERKDHSG (SEQ ID NO:3); YGLALERKDHSG (SEQ ID NO:4); KGGSINNNRWHSIYITRFGNMGS (SEQ ID NO:5); GGSINNNRWHSIYITRFGNMGS (SEQ ID NO:6); KGGTWYKIAFQRNRK (SEQ ID NO:7); GGTWYKIAFQRNRK (SEQ ID NO:8); KGGTSIKIRGTYSER (SEQ ID NO:9); GGTSIKIRGTYSER (SEQ ID NO:10); KYGTDIRVTLNRLNTF (SEQ ID NO:11); YGTDIRVTLNRLNTF (SEQ ID NO:12); KYGSETTVKYIFRLHE (SEQ ID NO:13); YGSETTVKYIFRLHE (SEQ ID NO:14); KYGKAFDITYVRLKF (SEQ ID NO:15); YGKAFDITYVRLKF (SEQ ID NO:16); KYGAASIKVAVSADR (SEQ ID NO:17); YGAASIKVAVSADR (SEQ ID NO:18); KGGNGEPRGDTYRAY (SEQ ID NO:19); GNGEPRGDTYRAY (SEQ ID NO:20); ...
