Description

Technical field:

[0001] The invention relates to the fields of medicine and biomedical engineering, in particular to a tissue engineered cartilage graft and a preparation method thereof. Background technique:

[0002] Cartilage tissue is a single tissue containing only chondrocytes, without blood vessels inside, and its nutrition mainly depends on the penetration of interstitial fluid. It is a kind of connective tissue that has the functions of supporting, protecting, and dispersing stress. Histologically, it can be divided into three categories: hyaline cartilage (articular cartilage, costal cartilage), elastic cartilage (ear cartilage), and fibrocartilage (meniscus). Structurally, chondrocytes are located within the cartilage lacuna and are surrounded by the surrounding cartilage capsule. The cartilage capsule acts as a barrier separating the chondrocytes from the surrounding tissue. Therefore, cartilage tissue has the characteristics of weak antigenicity and mild immune...
