Basic introduction of cartilage

Cartilage is a dense colloidal substance that is stronger but resilient than bones. It is the main component of many protozoa such as shark bones. On the human body, nose and ears and containing cartilage used to fill tissue. A translucent, elastic tissue that forms the bones of vertebrate embryos and small larvae, and most of the higher vertebrates are transformed into bones, but the original species (such as sturgeon and gill fish) are retained for life , The main ingredient for the bones.

A connective tissue in a human or vertebrate body. In the embryonic period, most of the human bones are composed of cartilage. Adult body only the tip of the nose, the outer ear, the tip of the ribs, vertebral connection surface, etc. have cartilage.

Human and vertebrate-specific embryonic bones. Can be divided into transparent cartilage, elastic cartilage and fibrous cartilage, as a slightly elastic tough tissue, in the body from the support and protection. Composed of chondrocytes, fibers and matrix. The matrix contains 70% of the water, the organic ingredients are mainly a variety of proteins, such as cartilage mucin, collagen and cartilage protein. In the fetus and young age, cartilage tissue distribution is broad, and later gradually replaced by bone tissue. Adult cartilage exists in the articular surface of bone, rib cartilage, trachea, auricle, intervertebral disc, etc.

The composition of cartilage

Cartilage is the only body in the body will not happen cancer, a few years ago was hype, said that because the shark's cartilage does not produce cancer, so the shark has anti-cancer effect .In fact, sharks are cartilage, cartilage is not cancerous , Does not long cancer. (Does not occur cancer does not mean no malignant transformation, cartilage tissue can be malignant, such as: chondrosarcoma).

Cartilage from cartilage tissue and its surrounding perichondrocytes, cartilage tissue from chondrocytes, matrix and j collagen fibers. According to the different components contained in the cartilage tissue, cartilage can be divided into transparent cartilage, elastic cartilage and fibrous cartilage three, in which the distribution of transparent cartilage is wide, the structure is also typical. Cartilage is a support tube with a certain degree of hardness and elasticity. In vertebrates are very well developed, generally seen in the adult part of the bones and respiratory tract and other tubular wall, the friction surface of the joints and so on. The majority of the initial bones were made up of cartilage (Cartilage model), which was later replaced by bone tissue. Most of the bones of cartilage fish are also cartilage. In the invertebrates, the cortical cartilage of the mollusks is well developed. The pericardium is generally coated with fibrous connective tissue pericardium, which is converted into periosteum when the cartilage is replaced by bone.

Cartilage regeneration

1, xenotransplantation. That is, the use of other species of cartilage grafts in the human articular cartilage, but because of its strong immune rejection and other issues, the study is still in the basic experimental stage.

2, autologous cartilage transplantation. The method is mainly through autologous parts of the cartilage transplantation, or through autologous white blood cells, stem cells to cultivate cartilage, eliminating the risk of surgery. But autologous cartilage transplantation source is limited, to patients with secondary trauma and increase patient pain, the technology is not yet mature and limited application.

3, allogeneic cartilage transplantation. Allogeneic cartilage transplantation has a wide range of sources, good biological performance, is expected to become an ideal cartilage graft, and achieved some clinical results, but it still exists immune rejection, disease transmission, bone graft bone graft, joint instability, Cartilage collapse and other issues, affecting the long-term survival of the graft in the body, the current study can not be ignored. In addition, the method requires a higher degree for patients, and is generally not suitable for diffuse degenerative arthritis and rheumatoid arthritis.

4, intake of special cartilage to promote autologous cartilage regeneration. The method uses uptake to promote the proliferation of human chondrocytes, hyperplasia of cartilage nutrition to achieve the purpose of cartilage regeneration, the method is similar to traditional Chinese medicine food homologous, but here the special cartilage is to promote the regeneration of cartilage sawfish spider cartilage powder. As early as the end of the last century, Japan, Europe and the United States long-term clinical research concluded that the intake of pure natural sawfish shark cartilage powder after a certain amount of time to make the majority of patients to achieve cartilage regeneration in Japan to 100 proud shark as an outstanding representative. This method because of its no side effects, simple and easy to remove the pain of surgery, the public can generally accept, now gradually as a substitute for medical use in clinical, and clinical medicine by the cartilage regeneration confirmed. But this method is also a weakness, the recovery of cartilage regeneration time needs a few months to a year or so, the cost of raw materials because of scarcity, process harsh, a large number of market demand than ordinary drugs.

How to protect cartilage tissue in life

Cartilage in the human body to play load-bearing, reduce inter-joint friction and other important role. In daily life, should exercise as much as possible in order to promote the joint blood circulation. However, the movement can not be excessive, and now a lot of joint disease, are caused by cartilage injury. Such as bone hyperplasia, lumbar disc herniation, meniscus injury, degenerative arthritis and so on. In the usual diet, should be a lot of intake of antioxidant foods such as mango, papaya, melon, grapes, oranges, pineapples, bananas, strawberries, tomatoes, cabbage, potatoes and so on. And once the body of the cartilage damage, can take some products can promote the regeneration of cartilage, such as sawfish shark cartilage powder.
