Which cells are responsible for bone formation?

Explanation:
Osteoblasts are the cells that build bone. They produce the organic matrix (osteoid) and drive mineralization with calcium phosphate to form new bone tissue. They originate from mesenchymal stem cells and act as the builders in bone formation. Once they finish forming bone, some become embedded in the matrix as osteocytes, which maintain the bone. Osteoclasts, by contrast, break down bone tissue, enabling remodeling. Chondroblasts form cartilage rather than bone, and cartilage can serve as a template that is later replaced by bone in development, but the direct bone-forming cells are osteoblasts.
