15.1/15.2 POJA-L7018+7033 Electron micrographs of hyaline cartilage versus elastic cartilage
Title: Electron micrographs of hyaline cartilage versus elastic cartilage
Description:
Differences between hyaline cartilage (A) and elastic cartilage (B).
(A): Hyaline cartilage (rat, costa).
(1): Perichondrial chondroblast.
(2): The first chondrocyte producing fibrillar matrix.
(3): Electron-dense chondrocyte with increased microvillar projections.
(4a to 4b): Gradient of increasing fibrillar matrix.
(B): Elastic cartilage (gerbil, auricle).
(5): Chondrocyte with nucleus, the cytoplasm with organelles partly visible. The chondrocyte is embedded in a matrix with varying amounts of young/mature elastin and bundles of collagen fibrils longitudinal as well as cross-sectioned. Immature elastin is recognisable as so-called oxytalan (pre-elastic) fibres while mature elastin displays a whitish-grey amorphous mass with denser stained microfibrils.
(6): Mature elastin. Close to the mature elastin at the lower bottom (6) dark grey fluffy spots crossed by fibrils reflects young elastin or so-called oxytalan (pre-elastic fibres).
Keywords/Mesh: locomotor system, cartilage, hyaline, elastic, matrix, chondrocyte, collagen fibril, oxytalan fibril, electron microscopy, POJA collection
