osteoblasterna
Osteoblasts are specialized cells responsible for the formation of new bone tissue. They originate from mesenchymal stem cells and play a crucial role in the process of bone remodeling, which is the continuous cycle of bone resorption and formation. Osteoblasts synthesize and secrete the organic components of bone, known as osteoid, which is primarily composed of collagen. This osteoid then undergoes mineralization, where calcium and phosphate ions are deposited, transforming it into mature bone.
These cells are found on the surfaces of bone where growth or repair is occurring. They are
