Human Osteoblasts-femoral

Bone is a dynamic tissue, being continuously remodeled by the coordinated actions of osteoclasts and osteoblast. Osteoblasts, the bone-forming cells, are derived originally from pluripotent mesenchymal stem cells. They synthesize and secrete organic extracellular matrix, osteoid, which is composed primarily of type I collagen. Osteoid is calcified by osteoblasts and during this process the cells become encased in lacunae within the calcified material and become osteocytes. Osteoblasts express protease-activated receptor-1 and vascular endothelial cell growth factor. Studies show that leukemia inhibitory factor can bind to the osteoblast cell surface and induce bone formation both in vitro and in vivo. The balance between osteoblast recruitment, proliferation, differentiation and apoptosis in sutures between cranial bones is essential for calvarial bone formation.

HO-f from ScienCell Research Laboratories are isolated from human femur. HO-f are cryopreserved at passage one and delivered frozen. Each vial contains >5 x 10^5 cells in 1 ml volume. HO-f are characterized by the cytochemical detection of Alkaline Phosphatase staining and/or mineral deposition. HO-f are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HO-f are guaranteed for 15 population doublings under the conditions provided by ScienCell Research Laboratories.

Recommended Medium

It is recommended to use Osteoblast Medium (OsM, Cat. #4601) for the culturing of HO-f in vitro.
