Cell Line Origin
Primary Human Chondrocytes (HCH) are isolated from normal human articular cartilage from the knee and hip joints (lot specific source information is available on request) and are provided in a cryopreserved format. HCH are routinely tested for their capacity to differentiate in 3D spheroids.The articular cartilage covers the joints between bones and contains no blood vessels, lymphatic vessels, or nerve fibers. It is composed of only one specialized cell type, the chondrocytes, which produce and maintain the extracellular matrix of cartilage, i.e. collagen (mostly type II) and proteoglycans (primarily aggrecan).
Rigid quality control tests are performed for each lot of Human Chondrocytes. They are tested for cell morphology, adherence rate, and cell viability. Furthermore, each lot is routinely tested for the capacity to differentiate in 3D spheroids. Growth performance is tested through multiple passages up to 10 population doublings (PD) under culture conditions without antibiotics and antimycotics. In addition, all cells have been tested for the absence of HIV-1, HIV-2, HBV and HCV, and microbial contaminants (fungi, bacteria, and mycoplasma).
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.
