Application

Primary Human Osteoblasts (HOB) are isolated from femoral trabecular bone tissue from the knee or hip joint region (lot specific source information is available on request). They stain positive for alkaline phosphatase and can be mineralized using PromoCell Mineralization Medium.Osteoblasts are of mesenchymal origin and are mainly responsible for bone formation and remodeling. In vivo, they produce a collagen type I rich extracellular matrix called the osteoid. During their development, osteoblasts undergo a maturation process called osteogenesis. When they become encased in the bone matrix, they stop proliferating and become osteocytes.

Other Notes

The Cell Pellets can be stored indefinitely at -20°C, and for up to 1 month at 4°C. Note: The Cell Pellets will not freeze at -20°C. Always centrifuge product briefly before opening vial.

Physical form

Pellet is dissolved in RNAlater^® for downstream analysis of DNA, RNA or protein profiles. Cells are not revivable.

Quality

Rigid quality control tests are performed for each lot of the corresponding cells. They are tested for cell viability, cell morphology, growth performance and for cell-type specific markers. In addition, all cells have been tested for the absence of HIV-1, HIV-2, HBV, HCV, HTLV-1, HTLV-2 and microbial contaminants (fungi, bacteria, and mycoplasma).

Warning

Although tested negative for HIV-1, HIV-2, HBV, HCV, HTLV-1 and HTLV-2, the cells – like all products of human origin – should be handled as potentially infectious. No test procedure can completely guarantee the absence of infectious agents.
