- Cartilage is a connective tissue whose cells, called chondrocytes, secrete a very specialized matrix. The basophilia of the matrix is due to the GAGs in its ground substance, specifically hyaluronic acid, chondroitin sulfate and keratan sulfate.onnective tissue is the most diverse of the four tissue types with a wide variety of functions. It ranges in consistency from the gel-like softness of areolar connective tissue to the hardness of bone. Blood is also a connective tissue.

Cartilage Cartilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of cartilage.Chondroblasts that get caught in the matrix are called chondrocytes. Cartilage does not contain blood vessels (avascular) or nerves (aneural).artilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of cartilage.

Chapter 2: The locomotor system A bone is composed of several tissues, predominantly a specialized connective tissue that is, itself, called “bone.” Bones provide a framework of levers, they protect organs such as the brain and heart, their marrow forms certain blood cells, and they store and exchange calcium and phosphate ions.yaline Cartilage Joints. This type (synchondrosis) is a temporary union. The hyaline cartilage that joins the bones is a persistent part of the embryonic cartilaginous skeleton and as such serves as a growth zone for one or both of the bones that it joins.

I. Cartilage Both bone and cartilage contain living cells embedded in an intercellular matrix. In bone, these cells are called osteocytes, which likewise occupy lacunae. However, the intercellular matrix of bone contains more collagen than found in cartilage and it is heavily mineralized with calcium salts.

I. Cartilage Once the osteoblasts are surrounded by bone matrix, they are referred to as osteocytes. The osteocytes are nondividing cells that sit in lacunae and extend their cytoplasmic processes outward through the canaliculi. Neighboring osteocytes are interconnected through gap junctions in these cytoplasmic processes.yaline cartilage is somewhat pearly-white in appearance. It consists of an intercellular matrix, in which numerous chondrocytes are embedded. During development, the sites in the body where cartilage will form become surrounded by a fibrous connective tissue covering called the perichondrium.

- Aetna considers matrix-induced chondrocyte implantation including the use of Bio-Gide (resorbable bilayer membrane made of porcine collagen) experimental and investigational for the treatment of osteochondral defects/lesions and all other indications because its effectiveness has not been established.here are no adequate prospective clinical studies of the effectiveness of autologous chondrocyte implantation on defects of the patella or talus. Prospective, randomized clinical studies are needed to assess the impact on functional status, disability, and pain.

What does it mean when you dream about bones? Bones consist of bony tissue, periosteum, marrow, blood and lymphatic vessels, nerves, and, in many cases, cartilage. Bony tissue, the main constituent, forms lamellae; the bone is considered compact or cancellous (spongy) according to the density of these lamellae.nder the appropriate stimuli, these primitive stromal cells mature to bone-forming cells at targeted sites in the skeleton. Under different stimuli, they are also capable of developing into adipocytes (fat cells), muscle cells, and chondrocytes (cartilage cells).

- Mesenchymal cells aggregate and begin to secrete matrix that is characterized by bundles of collagenous fibers. The secreted osteoid matrix has a high affinity for calcium salts, that are brought into the area of bone formation by the circulatory system. These deposit within and on the matrix to form calcified bone.. chondroblasts-immature cartilage cells. Secrete extracellular matrix, but are not yet rigidly embedded in that matrix. 3. chondrocytes-mature cartilage cells that are embedded in rigid extracellular matrix. These cells reside in small spaces within the matrix that are called lacunae.

Cartilage Regeneration and Osteoarthritis Chondrocytes are the only cells found in cartilage. Chondrocytes produce and maintain the cartilage matrix. Articular cartilage serves as the cushion and shock absorber within the joint as it lines the ends of the two bones that form the joint. Cartilage damage can be caused by several conditions including:

Chronic Inflammation 1-2 Granulation tissue is an example of fibrovascular proliferation. Granulation tissue contains new small blood vessels, fibroblasts, and mononuclear cells in an edematous extracellular matrix; formation of granulation tissue is part of the repair response. A granuloma is a form of chronic inflammation.

Cartilage They are further classified into loose connective tissues, dense connective tissues, cartilage tissues and other connective tissues, such as bone tissues, blood, and lymphatics. Cartilage is a type of connective tissue whose extracellular matrix contains large amounts of mucopolysaccharide, particularly chondroitin sulphate. The cellular component of cartilage tissues is the chondrocytes. The chondrocytes are chondroblasts that became trapped in the extracellular matrix.

- (Science: pathology) connective tissue dominated by extracellular matrix containing collagen type II and large amounts of proteoglycan, particularly chondroitin sulphate. cartilage is more flexible and compressible than bone and often serves as an early skeletal framework, becoming mineralised as the animal ages.Cartilage is produced by chondrocytes that come to lie in small lacunae surrounded by the matrix they have secreted.Please contribute to this project, if you have more information about this term feel free to edit this page.This page was last modified on 3 October 2005, at 21:16.This page has been accessed 17,927 times.What links here | Related changes | Permanent link.lease contribute to this project, if you have more information about this term feel free to edit this page.

Histology@ Yale Fibroblasts are by far the most common native cell type of connective tissue. The fibroblast synthesizes the collagen and ground substance of the extracellular matrix. These cells make a large amount of protein that they secrete to build the connective tissue layer. Some fibroblasts have a contractile function; these are called myofibroblasts. Chondrocytes and osteocytes form the extracellular matrix of cartilage and bone. More details and chondrocytes can be found later in this laboratory; osteocytes will be covered in the Laboratory on Bone. The macrophage is the connective tissue representative of the reticuloendothelial, or mononuclear phagocyte, system.

- Unlike other connective tissues like bone, cartilage does not contain blood vessels. Therefore, cartilage grows and repairs more slowly. However, this repairing capability is limited. Remember that chondrocytes are bound in a space called the lacunae; therefore, they cannot move to a damaged area to repair it.

Chondroblast Chondroblasts, or perichondrial cells, is the name given to mesenchymal progenitor cells in situ which, from endochondral ossification, will form chondrocytes in the growing cartilage matrix. Another name for them is subchondral cortico-spongious progenitors.[1] They have euchromatic nuclei and stain by basic dyes.
