FIGURE 1.
The expression of vitamin D receptor (VDR) in rhesus macaque follicles developed in vivo. Immunohistochemistry was performed without (A) or with (B,C) counterstain hematoxylin to allow for visualization of the VDR nuclear and cytoplasmic staining. Mouse non-immune IgG was used as the negative control (C insert). PM, primordial follicle; PR, primary follicle; SD, secondary follicle; SA, small antral follicle; LA, large antral follicle. Scale bar = 100 μm for (A,C), and 50 μm for (B).
