Smooth muscle tissue is found in the tunica media layer of large and small blood vessels and in the walls of hollow organs like the bladder and the uterus. Smooth Muscle Cells (SMC) possess all the same types of filaments, but, depending on the tissue of origin, differ significantly in mechanical and physiological properties. Therefore, AcceGen Biotech offers a range of Human Smooth Muscle Cells produced at AcceGen Biotech's cell culture facility from normal human tissue of different origins. The cells are isolated from the aorta, the coronary artery, the pulmonary artery, the umbilical artery,the trachea, the bronchi, the bladder,the prostate, and the uterus. Shortly after isolation, all AcceGen Biotech Human Smooth Muscle Cells are cryopreserved at passage 2 (P2) using AcceGen Biotech's proprietary, serum-free freezing medium, Cryo-SFM. Each cryo vial contains more than 500,000 viable cells after thawing.Proliferating cell cultures are made from 500,000 cryopreserved cells that have been thawed and cultured for three days at AcceGen Biotech.
