BRANCHED POLYPEPTIDES AND THEIR USE IN PROMOTING ADHESION OF CELLS TO SOLID SURFACES

摘要

Disclosed are novel poly{Lys(c[Arg-Gly-Asp-D-Phe-Cys(CH2CO)]i-Serj-DL-Alam)} branched peptide polymers wherein m is 1 to 7, j is 0.7 to 1.0 and i is 0.01 to 0.5. The use of said polypeptides in serum-free attachment of cells to solid surfaces is also disclosed. The herein-disclosed novel polypeptides are especially useful for serum- free attachment of stem cells to solid surfaces.
