Detailed explanation-1: -The cartilages are elastic in nature and are made up of connective tissues. The important protein present in the cartilage is chondrin. It is a gelatinous substance and forms a complex with carbohydrates.
Detailed explanation-2: -Chondrin is a bluish-white gelatin-like substance, being a protein-carbohydrate complex and can be obtained by boiling cartilage in water. The cartilage is a connective tissue that contains cells embedded in a matrix of chondrin. Chondrin is made up of two proteins chondroalbunoid and chondromucoid.
Detailed explanation-3: -Chondroitin is the protein found in cartilage. Ossein is the protein that makes up much of the organic matter in the bone.
Detailed explanation-4: -Among all the protein receptors expressed by chondrocytes, RDC1, Histamine receptors, TLR9, LRP5, LRP6, CCR7, CCR7 have the most important role in OA development, whereas VEGF-R, 1 integrin, EP and Gi are the major activators of chondrocyte differentiation.
