Clonetics Human Lung Blood and Lymphatic Microvascular Endothelial Cell Systems are pure, optimized microvascular endothelial cells for use in bioresearch. Lung Blood (BECs) and Lymphatic Microvascular Endothelial Cells (LECs) are implicated in a variety of physiological processes such as immune response, pulmonary and vascular function as well as the formation of blood vessels in tumors. Clonetics Human Lung BECs and LECs are more biologically relevant for investigating disease conditions involving microvasculature and deliver consistent and meaningful results. Utilizing a unique isolation process, >90% pure populations of blood and lymphatic lung microvascular endothelial cells can be obtained. Optimized media and supplements are also available to ensure growth and performance of the cells in culture.
