WebJul 29, 2024 · Osteoblasts are bone-forming cells whereas osteoclasts are degradative cells that break down and reabsorb bone. During bone formation, the osteoblasts secrete materials that make up the bone matrix, and as they secrete them some of them are eventually trapped and buried in the bone matrix. WebThe fully differentiated osteoblast may be easily recognized in bone tissue. Its cuboidal shape, its position directly opposed to the bone surface and its capacity to produce calcified bone matrix are characteristic. Three other differentiation stages are also reasonably well defined--the preosteoblast, the osteocyte and the lining cell.
