Chondrocyte
The chondrocytes (of the Greek : χονδρο, cartilage, and χντος, cell) are the cells composing the Cartilage.
They are round and bulky cells (of a diameter from 20 to 40 µm) present in the cartilage. They have a bulky, round core and nucleole in its central area. They synthesize and degrade the components of the extracellular Matrice of the cartilage Collagène of the type II and IX in particular and Glycosaminoglycanne S, etc… and by certain aspects have functions close to those of the fibroblasts (cells of the Périchondre), principal cells of the conjunctive Tissu. The chondrocytes take part in the synthesis and of the maintenance of cartilagineux fabric.
The chondroplastes are small small boxes in the extracellular matrix, located at the base of the hard cartilagineuse mass, close to the head of the bone. The chondroplastes contain the chondroblastes which are futures chondrocytes in the course of cellular Différenciation, which express in particular many receivers with the Vitamine has and Vitamine D, with the parathyroidal Hormone (or PTH), with the estrogen S, with the Glucocorticoïde S.
