Osteoblasts are bone-forming cells that descend from osteoprogenitor cells. They form a protein mixture known as osteoid, which mineralizes to become bone. Osteoid is primarily composed of Type I collagen.Osteoblasts also manufacture hormones, such as prostaglandins, to act on the bone itself.steocytes: Osteocytes are mature bone cells that originate from osteoblasts, which have migrated into and become trapped and surrounded by bone matrix, produced by themselves. The spaces they occupy are known as lacunae.
In bone, there are osteoblasts (cells which build bone) and osteoclasts (cells which break down bone). In the bone marrow and spongy bone, there are hematopoietic cells (cells â¦ which make blood). Bone is a type of connective tissue that is made of specialized cells that all work together for a common function.Their cellular and extracellular matrix is what makes bone cells so unique.   Yes.Bones contain tissues and cells. They have cells called chondrocytes, osteoblasts, and osteocytes.one is a type of connective tissue that is made of specialized cells that all work together for a common function.
