Figure 1From: Association of radiotherapy with preferential depletion of luminal epithelial cells in a BRCA1 mutation carrier Irradiated breast tissue has a diminished luminal compartment. A. Flow cytometry analysis of cancer-free tissue from the non-irradiated and irradiated breasts of a BRCA1 mutation carrier. (B). Immunohistochemistry shows more prominent basal/myoepithelial cells (brown) than luminal cells (red) in irradiated vs. non-irradiated breast glands.Back to article page
