Immunohistochemical staining showing intratumoral and intrastromal FOXP3+ T regs in breast cancer tissues. Representative micrographs at × 530 magnification of CD3+ (red color membranous expression) and FOXP3+ (brown color nuclear expression) TIL of (A) intrastromal (left) and intratumoral (right) sections. Solid arrow indicates a CD3+/FOXP3+ Treg cell and dashed arrow indicates a CD3+/FOXP3- cell. (B) Intratumoral FOXP3+ TIL with different staining intensity (Intense, Medium, and weak). Cells were counterstained with hematoxylin.
