Transplant associated SCC (TSCC) shows diffuse Ki-67 staining and increased numbers of Ki-67+ cells.

<p>Representative immunohistochemistry at (a) 10X and (b) 20X, with (c) mean cell count values of Ki-67+ cells in SCC (n = 5) and TSCC (n = 5). T indicates tumor. Only cells along or within tumors were counted. Asterisks (*) indicate statistical significance, where *P<0.05. Bar = 100 µm. (d) Ki-67 (red) did not colocalize with CD3 (green) in SCC and TSCC. (e) Intracytoplasmic staining of CK5/6 (red) colocalizes with intranuclear staining of KI-67(green).
