Effects of weightlessness on chondrocytes and morphology. (A) Alcian blue staining results. (B) Safranin O staining results. (C) Col II staining results, magnified 500 μm on the left and 100 μm on the right. (D) Quantification IOD value for Col II. The black arrows indicate the articular cartilage area, and the red arrows indicate type II collagen-positive cells. “a” indicates a significant difference from the N group and “b” indicates a significant difference from the S2 group. N, ground group; S2, 14-day hindlimb unloading group; S4, 28-day hindlimb unloading group; Col II, Collagen Type II; IOD, integrated optical density.
