PROBLEM TO BE SOLVED: To provide a substrate material for culturing cell aggregates, hardly causing apoptosis, and capable of producing the cell aggregates having a high survival rate of the cultured cells.SOLUTION: This substrate material consists of a polypeptide (P) and a substrate material (B) and used for culturing the cell aggregates of adherent cells (S), wherein the (P) is the polypeptide having an amino acid sequence (X), and the (X) is at least one kind selected from the following pentapeptide sequence, the following hexapeptide sequence, Ala Gly Val Pro Gly Phe Gly Val Gly sequence (12) and Ala Gly Val Pro Gly Leu Gly Val Gly sequence (13), The pentapeptide sequence is: Gly Val Gly Val Pro sequence (1) or the like. The hexapeptide sequence is: Gly Val Gly Val Ala Pro sequence (6) or the like. |
