Effects of different doses of freeze-dried RJ on the histoarchitecture of seminiferous tubules at Post-Natal Days (PNDs 07, PNDs 14, PNDs 21 and PNDs 35) in mice. The images pasted with letter “CON” represent mice in control group, showing the normal features, the images pasted with letter “L-RJ”, ”M-RJ” and ”H-RJ” represent low dose of freeze-dried royal jelly treatment group, moderate dose of freeze-dried royal jelly treatment group and high dose of freeze-dried royal jelly treatment group, respectively. For each group and each stage, we captured three representative images. At PNDs 07, images were captured at the magnification of 40×. Bar 20 μm. Testis images of PNDs 14, PNDs 21 and PNDs 35 mice captured at the magnification of 20×. Bar 50 μm. Red arrows in PNDs 14 indicate the space of seminiferous tubules. Red arrows in PNDs 21 (L-RJ, M-RJ) indicate the seminiferous epithelium. Red arrows in PNDs 21 (H-RJ) indicate the abnormal space in the basal part of the seminiferous epithelium. Red arrows in PNDs 35 (H-RJ) indicate the un-synchronously seminiferous epithelium. Different markings inside the images were inserted through Adobe Photoshop CS5.
