Studies show that esophageal microvascular endothelial cells exhibit a strong inflammatory immune response to LPS, cytokines, and pH exposure, thus playing a critical regulatory role in esophageal inflammation [1]. When exposed to acidic pH, HEMEC express some proteins, such as VCAM-1, but not others, such as ICAM-1, which is speculated to selectively recruit leukocytes to the esophagus [2]. This could play a role in the cellular response triggered by gastroesophageal reflux disease. In vitro cultures of HEMEC have enabled scientists to observe leukocyte binding, upregulation of cell adhesion molecules, and other cellular responses to LPS, cytokines and pH exposure that indicate that HEMECs are intrinsically different from lower gastrointestinal endothelial cells in regards to an inflammatory immune response [3]. HEMEC from ScienCell Research Laboratories are isolated from human esophageal tissue. HEMEC are cryopreserved at passage one and delivered frozen. Each vial contains >5 x 105 cells in 1 ml volume. HEMEC are characterized by immunofluorescent method with antibodies to vWF/Factor VIII and CD31 (P-CAM) and by uptake of DiI-Ac-LDL. HEMEC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HEMEC are guaranteed to further culture in the conditions provided by ScienCell Research Laboratories.
It is recommended to use Endothelial Cell Medium (ECM, Cat. No. 1001) for the culturing of HEMEC in vitro.
HEMEC are for research use only. It is not approved for human or animal use, or for application in in vitro diagnostic procedures.
Directly and immediately transfer cells from dry ice to liquid nitrogen upon receiving and keep the cells in liquid nitrogen until cell culture needed for experiments.
Dry ice.
