Osteoblasts lay down the inorganic components
WebA fairly comprehensive view of osteoclastic ontogeny and function is emerging from recent studies. Osteoclasts dissolve bone mineral by massive acid secretion and secrete specialized proteinases that degrade the organic matrix, mainly type I collagen, in this acidic milieu.

Osteoblasts lay out a lot of bone matrix called osteoid. Osteoblasts that don’t produce matrix anymore but simply maintain it are called osteocytes. WebOsteoblasts within the cartilage secrete a matrix material called osteoid, a gelatinous substance made up of collagen and mucopolysaccharide, an organic glue. Soon after the osteoid is laid down, inorganic salts are deposited in it to form the hardened material recognized as bone.
