TM40D-COX2 tumors have increased apoptotic CD8+ T cells.

<p>Histological sections of TM40D and TM40D-COX2 tumors were stained with AlexaFluor 594 for CD8 (RED) AlexaFluor 488 for Cleaved Caspase 3 (ClCasp3+) (GREEN), and Dapi for nucleus (BLUE) (A and B, respectively). C. Quantitative analysis of panels A and B measuring the percent of CD8+ cells that have cleaved Caspase 3 co-localized to the cell. N = 3 samples per group, 8–10 sections per sample. *p<0.01 compared to TM40D.
