Cartilage tissues

TGF-Ps are pleiotrophic cytokines. They are capable of inhibiting the cell cycle and, hence, cell growth of several cell types, most notably epithelial and haematopoietic cells. These factors, however, stimulate the growth of other cell types, most notably cells that give rise to connective tissue, cartilage and bone. They induce the synthesis of extracellular matrix proteins and modulate the expression of matrix proteases. They also serve as a powerful chemoattractant for monocytes... 

In contrast to milk, where samples are primarily derived from cows, meat analysis has to be performed in samples of a widely different animal origin including cattle, lamb, swine, poultry, and fish. Muscle is a complex matrix with a pH of 5.7, composed of muscle fibers, various types of connective tissue, adipose tissue, cartilage, and bones. Sarcoplasmic proteins such as myoglobin, and glycolytic enzymes are soluble in water while the myofibrillar proteins such as myosin and actin are soluble in concentrated salt solutions (14). The connective tissue proteins, collagen and elastin, are insoluble in both solvents. 

Structure. Collagen is a widespread protein that provides a structural framework of intercellular tissue support in connective tissue, cartilage, bone and other tissues. Elastin is a stretchable support protein. Keratin is the tough protein of fingemails and hair.

Fibrous proteins, being insoluble in water often have a structural or protective function. The most familiar fibrous proteins are the keratins and collagen. a-Keratin (Figure 25.18) is based on the a-helix secondary structure and is the protein structural component of hair, wool, nails, claws, quills, horns, and the outer layer of skin. P-Keratin is based on the P-sheet secondary structure and occurs in silk as fibroin. L-Cysteine is especially abundant in keratins, where it can account for more than 20% of the amino acids present. Collagen occurs mainly in connective tissue (cartilage and tendons) and has a triple helix structure.

Due to the child s more flexible skeleton and increased amount of stretch allowed by the soft tissues, the majority of childhood fractures are undisplaced. Greater strength of the joint capsule and ligaments compared with the metaphyseal bone also means that fractures occur much more readily than dislocations. In the infant, hard tissues (cartilage and bone) may be considered as soft, while soft tissues (tendons and ligaments) should be considered as hard. 

PHA have been studied for medical implants applications such as heart valves, vascular tissues, bone tissues, cartilage replacements, nerve conduits, as well as esophagus tissues.

Many tissues have been produced in the lab, including heart, lung, liver, and kidney tissues cartilage and bone. Technologies such as three-dimensional printing of biomaterials have been demonstrated to produce a variety of tissues in the lab. 

The internal framework in mammals consists of connective tissue, cartilage and bone. These structures contain and bound the groupings of specialized epithelial cells—which are localized into organs which is turn are integrated to form the complete organism. From a biochemical point of view, the body framework is a network of connective tissue modified in certain regions to form cartilage and bone.
