Abstract
Provided are a composition for cell transplant and a method for cell transplant, both of which enable a myocardial tissue to favorably retain cardiac myocytes and/or cardiac progenitors and can improve the persistence and proliferation of transplanted cells. The composition for cell transplant of the present invention is a composition for cell transplant, containing cells and an aqueous solution containing a protein (A), the cells including a cardiac myocyte and/or a cardiac progenitor, the protein (A) having a degree of hydrophobicity of 0.2 to 1.2, the protein (A) containing a polypeptide chain (Y) and/or a polypeptide chain (Y′), the protein (A) containing 1 to 100 polypeptide chains as a total of the polypeptide chain (Y) and the polypeptide chain (Y′), the polypeptide chain (Y) being a polypeptide chain having 2 to 100 continuous amino acid sequences (X), the amino acid sequence (X) having any one of a VPGVG sequence (1) corresponding to an amino acid sequence of SEQ ID NO: 1, a GVGVP sequence (2) corresponding to an amino acid sequence of SEQ ID NO: 2, a GPP sequence, a GAP sequence, and a GAHGPAGPK sequence (3) corresponding to an amino acid sequence of SEQ ID NO: 3, the pol…
