ESC-Rep-CM retention in both PI and IR hearts after cell transplantation. a Representative in vivo bioluminescence images of PI and IR mice on the indicated days after ESC-Rep-CM transplantation. b Quantitative analysis of BLI signals in the PI and IR groups. n = 4 for each group. c Immunofluorescence of heart sections from the PI and IR groups at day 7 for human nuclear antigen (HNA, red), cardiac troponin I (TNNI3, gray), and cell nuclei (Hoechst 33342, blue). n = 3 per group.
