Abstract:
During endochondral bone formation, resistance to vascular invasion changes in association with differentiation and maturation of chondrocytes. Just prior to chondrogenesis, the vasculature regresses and avascular cartilaginous bone primodia appear. The anti-angiogenic barrier of cartilage is acquired through coordinate interactions of extracellular matrices and angiogenesis inhibitors. In the process of vascular invasion into cartilage, angiogenesis stimulators and matrix degrading enzymes play important roles. In this review, the association of angiogenesis with endochondral bone formation will be discussed.

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
