Endoplasmic Reticulum Stress (ER Stress) and Unfolded Protein Response (UPR) Occur in a Rat Varicocele Testis Model

Figure 3

H&E staining in the left seminiferous tubules of control (a, b) and varicocele (d, e) groups. L: lumen. I: inter seminiferous connective tissue. Se: Sertoli cell. Ps: primary spermatocyte. Sp: secondary spermatocyte. Sg: spermatogonia. M: myoid cell. Sz: spermatozoa. Dc: degraded cell. Le: Leydig cell. IBL: irregular basal lamina. The two asterisks in panels (d, e) point out at intracellular vacuoles. Representative TUNEL staining of left testis sections of control (c) and varicocele (f) groups. Arrows show the TUNEL⁺ germ cells. The graph on the right (g) show comparison of mean TUNEL⁺ germ cells between control and varicocele groups ( each). Independent -test was used for comparison two groups. Data was expressed as .
