T Cell-Related Rejection of Transplanted iPSC-CMs
(A) H&E, CD3, or CD4 staining of the harvested iPSC-CM grafts 1 month after transplantation. Scale bars, 500 μm (4×), 100 μm (20×).
(B) Semi-quantitative scoring of the number of CD3- or CD4-positive cells in the graft 1 month after transplantation. The results are shown as the means ±SD for group I (nos. 1 and 2) and group II (nos. 3–5). ∗p < 0.05.
