A Excerpt of a mildly degenerated cartilage sample from a nano-holotomography image (0.1 × 0.1 × 0.1 µm3 voxel size) showing two chondrocytes with their nucleus, shadows of cell organelles within their cytoplasm and unmasked fiber bundles, in between interterritorial matrix (scale 10 µm); B–E Transmission electron microscope images of cartilage; B + D chondron with × 3000 magnification (scale 2.5 µm); C Territorial matrix (left of blue line), immediately pericellular matrix (between lines), chondrocyte (on the right of the green line), × 12,000 magnification (scale 0.5 µm); E territorial matrix close up from image D (scale 0.5 µm)
