Purification of pluripotent stem cell (PSC)-derived cardiomyocytes is critical for the application of cardiomyocytes both in clinical and basic research. Finding a specific cell marker is a promising method for purifying induced cells. The present study employed phage display technology to search for particular cell markers that could bind specifically to PSC-derived cardiomyocytes. After three rounds of biopanning, several peptides were obtained. The ELISA results show the no. 3 sequence peptide (QPFTTSLTPPAR), and other four sequences having a consensus motif [SS(Q)PPQ(S)], no. 9, 11, 14, and 10, have relatively high affinity and specificity to cardiomyocytes. Immunofluorescence confirmed that the selected peptides could bind specifically to the PSC-derived cardiomyocytes. Competition tests with chemically synthesized peptides revealed the binding ability was caused by the peptide itself. Western blot analysis proved the phages were both bound to two 17 kDa cardiomyocyte membrane proteins and the no. 9 sequence showed a 55 kDa protein that was not observed in the no. 3 sequence. These results suggest that the selected peptides specifically target receptors on PSC-derived cardiomyocyte membranes. The results will pave the way for further studies of cell surface markers and their applications, such as labeling, purification, and as vehicles for drug delivery.
