Supplemental Figure S6 from Treatment-Induced Tumor Cell Apoptosis and Secondary Necrosis Drive Tumor Progression in the Residual Tumor Microenvironment through MerTK and IDO1

Supplemental Figure S6. Tumors harvested on treatment d 7 were assessed by IHC for FoxP3 and Arg-1. Representative images are shown. Original magnification = 400X. Asterisks represent areas of acellular debris. Black arrows indicate tumor infiltrating lymphocytes (TILs).
