Final answer:
Osteoblasts are the cells capable of migrating and depositing new bone. They initiate the formation of bone and differentiate into osteocytes, while osteoprogenitor cells divide to produce new osteoblasts.
Step-by-step explanation:
The type of cell capable of migrating and depositing new bone is the osteoblast. These are critical cells active in bone formation during growth and remodeling. Osteoblasts synthesize and secrete both the organic and inorganic parts of the extracellular matrix of bone tissue and are essential in the development of bone from fibrous membranes and hyaline cartilage, known as ossification. After depositing bone material, they become trapped in the matrix and differentiate into osteocytes, found in the lacunae of bone. Furthermore, osteoprogenitor cells, which are undifferentiated with high mitotic activity, are the only bone cells that divide, and they eventually differentiate and develop into osteoblasts.
