There are three cartilage types in the human body. Chondroblasts are actively dividing immature cells which form extracellular matrix and the chondrocytes. Elastic cartilage’s role is purely structural, offering flexibility and resilience due to a mixture of elastic fibers and type II collagen fibers. 5. Chondroblasts, also called chondroplasts, are immature cells, that are essential for cartilage development. Wiley Subscription Services, Inc., A Wiley Company, 26 Sept. 2005. Fibroblasts are found in all types of connective tissue. CONTENTS The ECM of cartilage contains three characteristic elements: A protein-based collagen matrix gives form and strength to cartilage tissue through a mesh-like structure of fibrils. In cartilage, these cells produce type I collagen. 5. At growth plates, chondrocytes regulate epiphyseal plate growth. The matrix is produced by fibroblasts (or related cell types -- chondroblasts in cartilage and osteoblasts in bone). Accordingly, each type has a particular location. They are present at the edges of the cartilage below the perichondrium, and at that place, the cell division comes about as two oppositional areas. Chondrocytes malfunction can lead to a disease called osteoarthritis. Therefore, to maintain the structure and function of the cartilage, chondrocytes should obtain nutrients from the matrix. With a pliable structure composed primarily of water, this tissue type is also extremely tough. The extracellular matrix of cartilage is secreted by chondroblasts, (chondro = cartilage), which are found in the outer covering layer of cartilage. What are the three characteristic elements of the ECM? For instance, 3NA tibia chondroblasts were surrounded by less cartilage extracellular matrix and were expressing Agc1 at a lower level than control cells at E13.5 (Fig. They are located along the edges of the cartilage under the perichondrium where the cell division occurs as two oppositional areas. Although there are many different forms of collagen in the human body, the collagen found in cartilage is primarily type II, with an attached FACIT (short for fibril-associated collagen with interrupted triple helix) XIV collagen which determines the diameter of these fibers. Chondrocytes produce components of the extracellular matrix and maintain the cartilage structure and function. Upon continued culture these cells spread onto the plastic surface and dedifferentiate. Chondroblasts produce extracellular matrix. 1. Cartilage is composed of specialized cells called chondroblasts and, unlike other connective tissues, cartilage does not contain blood vessels.
