Blood vessels with their cellular cargo invade the extracellular matrix; chondroclasts and osteoclasts digest the extracellular matrix that has been degraded by proteolysis by matrix metalloproteinases, and crystals of calcium phosphate are deposited in the debris. These are later reabsorbed by osteoclasts...
Inside the cavities of cancellous bone is soft, fatty tissue composed of an irregular network of blood vessels and cells called bone marrow. There are two types of marrow: red and yellow. Red marrow contains stem cells, unspecialized cells that can grow into different types of specialized cells...

Layers of calcium and phosphate salts build up and enclose the cartilage cells during ossification. Eventually, the cartilage cells perish. The cartilage cells leave behind microscopic spaces in the bone. Osteoblasts are specialised cells deposited into empty areas by blood vessels. ...
