What are osteoprogenitor cells?

osteoprogenitor cells are types of cells that work in bone growth or repair. These cells come from stem cells and are formed by progenitor cells. Also known as prereseoblasts, osteoprogenitor cells are found in the bone marrow. The bone marrow consists of several cell layers and is one of these layers that are located these prereseoblastic cells.

Osteoblastic cells play a major role in bone formation and repair. They exclude collagen fibers that help to harden the bone. Osteoprogenitors cells have the ability to evolve on osteoblasts. Each cell begins as a mesenchymal cell in the pulp. It then grows from a progenitor cell to an osteoprogenitor cell. From now on, the cells develop into osteoblasts and begin to grow or repair through intramembranous ossification or endochondral ossification.

Intramembranous ossification uses osteoprogenitor cells to direct bones. Many bones are formed during the child. Into whichThe groups include bones that are formed, while the child is still in the womb, such as the skull. Some forms of bone repair will also use intramembranous ossification, depending on the level of movement they need the bones.

Endochondral ossification uses osteoprogenitor cells to form cartilage. This method forms long bones of the body, such as the bones of the femur in the thigh. Chondrocytes that are cartilage cells regenerate quickly and calcify to strengthen the extracellular matrix of existing cartilage cells. The osteoprogenitarian cell cannot create or repair the bones that are calcified. In order to allow access, other cells are brought by blood cells to break the calcified matrix sufficiently so that the group of osteoprogenitor cells form bones.

osteoprogenitor cells are found in the inner layer of periostea. Periosteum is part of the bone used for the HEPAchy, ligaments and muscles. This external membrane provides a connection point. There is also a concentration of osteoprogenitor cells in the endoste. The endosteum limits the inner surfaces in the bones.

Some bone grafts rely on mesenchymal progenitor cells. The embryo contains these cells that contribute to the development of blood and lymphatic vessels, connective tissues and blood. Progenitor cells are used to stimulate osteoprogenitor cells when the patient does not have a large number of progenitor cells to heal the bones properly. One example of this application is dental reconstruction and patients suffering from extreme or chronic bone damage can also benefit from stimulation using progenitor cells.
