人心房成纤维细胞-胎儿

Cardiac fibroblasts (CF) provide structural support for cardiac myocytes and are responsible for extracellular matrix synthesis in the heart during growth and pathophysiological conditions. CF are an important cellular component of myocardial responses to injury and the source of paracrine growth factors. Their proliferation and synthesis of matrix is essential for scar formation at sites of myocardial infarction and cardiac fibrosis. CF cultures have been widely used as a model to study the cardiac matrix remodeling by physiological (exercise) and pathological (hypertension) stressors. CF also has been found to form electric coupling with myocytes through gap junctions exerting electrotonic influences on the cells. These electronic couplings are suggested to play an important role in genesis of complex fractionated atrial electrogram sites and thus are a perfect model for study of atrial fibrillation.HCF-fa from AcceGen Research Laboratories are isolated from the human fetal atrium. HCF-fa are cryopreserved at secondary culture and delivered frozen. Each vial contains >5×10^5 cells in 1 ml volume. HCF-fa are characterized by immunofluorescence with antibody specific to fibronectin. HCF-fa are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HCF-fa are guaranteed to further expand for 15 population doublings under the conditions provided by AcceGen Research Laboratories.
