Figure 3From: Effect of in uteroexposure to diethylstilbestrol on lumbar and femoral bone, articular cartilage, and the intervertebral disc in male and female adult mice progeny with and without swimming exercise Representative safranin O-fast green-stained histologic sections. (a) Normal articular cartilage from female swim control. Single-headed arrow shows chondrocytes clones. Double-headed arrow demonstrates subchondral bone thickness. (b) Male swim 1.0 DES limb; note abundant chondrocyte clones (single-headed arrow) and fibrillation (arrowhead). (c) Male swim, 1.0 DES. Note paucity of staining, chondrocytes proliferation, and duplication of tide mark (white arrowhead).Back to article page
