Ultrastructure of chondrocytes in DNOAP group and Toluidine blue staining of chondrocytes in two groups. (a) The chondrocytes are located in the cartilage vortex (4x) under transmission electron microscope; (b–d) they were amplified by 10×, 30× and 50×, respectively, showing the formation of a large number of vesicles in the cytoplasm, significant mitochondrial swelling, intima rupture, mitochondrial crest arrangement disorder (c, red arrow), and obvious swelling of the Golgi apparatus and endoplasmic reticulum (d, yellow arrow). (e) Representative pictures of chondrocytes of toluidine blue staining in DNOAP group and control group.
