osteoblasts secrete matrix; bone deposition
A protein secreted by osteoblasts during bone deposition is collagen. The collagen is put down in layers parallel to the long axis of the bone alternating with layers at right angles to the long axis of the bone, kind of in a cross-hatching pattern.
Osteoclasts (Osteo - bone, clast - make or create)
Osteoblasts are needed to create bone. Osteoclasts destroy bone.
The cells that build bone are called OSTEOBLASTS.
The cell type that is responsible for bone matrix is the Osteoblast. Osteoblast's form a protein mixture known as osteoid, which materializes to become bone. They also manufacture hormones to act on the bone itself.
Cells that form bones are called osteoblasts.
Osteoblasts
Bone building cells are called osteoblasts. These osteoblasts are responsible for both building and repairing the bone tissues in the body.
