Although the word chondroblast is commonly used to describe an immature chondrocyte, the term is imprecise, since the progenitor of chondrocytes (which are mesenchymal stem cells) can differentiate into various cell types, including osteoblasts
choanocyte. n. 1. (Zoology) any of the flagellated cells in sponges that maintain a flow of water through the body. A collar of protoplasm surrounds the base of the flagellum. Also called: collar cell.
Chondrocytes are mature cells found in cartilage. They make up the cellular matrix of cartilage, performing a number of functions within the tissue, including facilitating the exchange of fluids through the gelatinous layers. Because cartilage lacks vascularization, it relies on this exchange to receive nutrients and express waste materials.
