From: Concentric lamellae – novel microanatomical structures in the articular calcified cartilage of mice
TEM micrographs of the medial femoral condyle from a 53 week old BALB/c AKU mouse. (a) HAC and ACC with the tidemark, which separates the two types of articular cartilage, have been labelled. A hypertrophic chondrocyte can be seen deep in the ACC. (b) Chondrocytes undergoing chondroptosis were visible in the ACC. Concentric lamellae were also visible surrounding the cells (dashed lines). The cement line which separates the ACC from the underlying SCB is highlighted (x1250). Tissue fixed in glutaraldehyde. Scale = 10 µm.
