Uberon definition : Skeletal tissue that is avascular, rich in glycosaminoglycans (GAGs) and typically
includes chondrocytes within isolated lacunae. Cartilage tissue is deposited by chondroblasts.;
Uberon related term : portion of cartilage tissue; cartilages; cartilage;
Uberon Homology note : Phylogenetic analysis suggests that cartilage arose independently in cnidarians, hemichordates,
vertebrates, arthropods, annelids, brachiopods, and molluscs - or a common ancestor
of brachiopods and molluscs (...). Analyses of cartilage as a tissue and of the development
of invertebrate cartilages are consistent with homology between invertebrate and vertebrate
cartilage. From the discussion above, it will be clear that understanding genetic
changes underlying cartilage evolution is key to determining whether the multiple
origins of cartilage represent parallel evolution.[well established][VHOG];
