Fibroblasts are mesenchymal cells derived from the embryonic mesoderm. They have been extensively used for a wide range of cellular and molecular studies as they are one of the easiest types of cells to grow in culture. Their durability also makes them amenable to a variety of manipulations ranging from studies employing gene transfection to microinjection. There is evidence showing that fibroblasts in various organs are intrinsically different . Specifically, human pulmonary artery adventitial fibroblasts (HPAAF) are important modulators of vascular wall function . During pathological conditions, such as hypoxia-induced pulmonary hypertension, HPAAF become proliferative which contributes to adventitial thickening .
iXCells Biotechnologies provides high quality HPAAF, which are isolated from human pulmonary artery and cryopreserved at P1, with >0.5 million cells in each vial. HPAAF express fibronectin and are characterized by their spindle-shaped morphology. They are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi and can further expand for 16 population doublings in Fibroblast Growth Medium(Cat# MD-0011) under the condition suggested by iXCells Biotechnologies.
