The NMBR immunostaining results in the kidney (A), testis (B), epididymis (C), ductus deferens (D), ovary (E), uterus (F). High magnification of NMBR-positive cells in the proximal tubule and the distal tubule of the renal cortex (a); the leydig cells (1) (denoted by an arrow) (b); the pseudostratified columnar epithelium of the epididymal duct (1) (denoted by an arrow) (c); the pseudostratified epithelium (1) (denoted by an arrow) and muscular layer of the ductus deferens (d); the primary follicle, the secondary follicle (1) (denoted by an arrow) and the granulosa cells (2) (denoted by an arrow) (e1 and e2); the myometrium (1) (denoted by an arrow) (f1) and endometrium (2) (denoted by an arrow) (f2). Negative controls in the kidney (A0), testis (B0), epididymis (C0), ductus deferens (D0), ovary (E0), uterus (F0). Scale bars in (E, F and F0) = 100 μm, (A, B, C, D, A0, B0, C0, D0 and E0) = 50 μm, (a, b, c, d, e1, e2, f1 and f2) = 20 μm.
