What are osteoblasts? What are osteoclasts?

Expert Solution

Osteoblasts are bone forming cells. They are cells with single nucleus that synthesize bone. They also come from the bone marrow and related to structural cells. They work in teams to build bone. They produce newbone called osteoid which is made of bone collagen and other protein. Then they control calcium and mineral deposition. They are found on the surface of the newbone. When the team of osteoblasts has finished filling in a cavity, the cells become flat and line the surface of the bone. These old osteoblasts are called Lining cells. They regulate passage of calcium into and out of the bone, and they respond to hormones by making special proteins that activate osteoclasts.

Osteoclasts are larger cells that dissolve the bone. They come from the bone marrow and related to white blood cells. They are formed from two or more cells which fused together so they have more than one nucleus. They are found on surface of bone mineral next to the dissolving bone.

Deposition of osteoid by osteoblasts – the first step in establishment of the ECM of bone – requires a suitable substrate as well as presence of nearby blood vessels. These requirements suggest some features of the substrate and blood vessels are necessary to activate osteoblasts; although I do not know what these features are, presumably they include some sort of signal molecules necessary to activate osteoblasts. Given the manner in which developing bone increases in size – particularly through appositional...

Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity. They are derived from precursors in the myeloid/ monocyte lineage that circulate in the blood after their formation in the bone marrow. These osteoclast precursors (OCPs) are attracted to sites on bone surfaces destined for resorption and fuse with one another to form the multinucleated cells that resorb calcified matrixes under the influence of osteoblastic cells...
