Figure 8. Immunohistochemical localization of ATM in nonretinal cells of adult mouse ocular tissue sections. ATM immunolabeling was observed in corneal epithelial (CEp), corneal stromal (CS), and corneal endothelial (CEn) cells (A); in the lens epithelium (Le), transitional zone (Tz) and lens fiber (Lf; B); in iridal cells (C) and in the pigmentary ciliary epithelium (PCE) and nonpigmentary ciliary epithelium (NPCE) cells (D). ATM immunoreactivity is primarily detected in the nucleus of nonretinal ocular cells
