Product Description

Bone is a dynamic tissue, being continuously remodeled by thecoordinated actions of osteoclasts and osteoblast. Osteoblasts, the bone-formingcells, are derived originally from pluripotent mesenchymal stem cells. They synthesizeand 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 [1]. Studies show that leukemia inhibitory factor can bind to the osteoblast cell surface and induce bone formation both in vitro and in vivo [2]. The balance between osteoblast recruitment, proliferation, differentiation and apoptosis in sutures between cranial bones is essential for calvarial bone formation [3].

iXCells Biotechnologies provides high quality Human Osteoblasts-Femoral (HOb-f), which are isolated from human femur and cryopreserved at P0, with >0.5 million cells in each vial. HOb-f are characterized by the cytochemical detection of AP and mineral deposition. These HOb-f are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi and can further expand for 12 population doublings in Osteoblast Growth Medium (Cat# MD-0054) under the condition suggested by iXCells Biotechnologies.
