Compare Osteoblast and Osteoclast

Osteoblast vs Osteoclast
(Similarities and Differences between Osteoblast and Osteoclast)

Osteoblasts and Osteoclasts are the two types of bone cells which constitute the bone tissue or the osseous tissue. The bone is a metabolically active tissue consisting of several types of cells among which the Osteoblasts and Osteoclasts are the most important ones. Osteoblasts are responsible for the formation of bone whereas the osteoclasts are responsible for the breakdown of the bones. The coordinated actions of these two cells are required for the formation and resorption (breakdown) of bones. This coordinated action between osteoblasts and osteoclasts is known as Bone Remodeling. Bone remodeling also ensures the maintenance of bones and the regulation of mineral levels, particularly calcium and phosphorous, in the body.

Similarities between Osteoblasts and Osteoclasts

Ø  Both osteoblasts and osteoclasts are bone cells.

Ø  Both are involved in bone remodeling.

Ø  Both are involved in the repair of bones.

Ø  Both are living cells with nucleus.

Ø  Both are metabolically very active cells.

Ø  Both cells are located on the surface of osteon seam.

Ø  Both are connective tissues.
