Brain microvascular endothelial cells (BMEC), the major component of the blood-brain barrier, limit the passage of substances, both soluble and cellular, from the blood into the brain. BMEC utilize unique features to distinguish themselves from peripheral endothelial cells, such as 1) intercellular tight junctions that display high electrical resistance and slow paracellular transport, 2) the absence of fenestrae and a reduced level of pinocytic activity, and 3) the expression of specialized pumps that can transport compounds out of the brain via the blood-brain barrier [1- 3]. Similar to peripheral endothelial cells, BMEC express, or can be induced to express, cell adhesion molecules on their surface that regulate the extravasation of leukocytes into the brain. Cultured bovine BMEC have been used for studying the molecular and cellular properties of blood-brain barrier because of their unique functions .
BBMEC are characterized by immunofluorescence with antibody specific to vWF/Factor VIII. BBMEC are negative for mycoplasma, bacteria, yeast, and fungi.
BBMEC are guaranteed to further expand for 5 population doublings under the conditions provided.
It is recommended to use Endothelial Cell Medium (ECM, Cat. SC1001) for culturing BBMEC in vitro.
BBMEC are for research use only. They are not approved for human or animal use, or for application in in vitro diagnostic procedures. HA are for in vitro laboratory science research use only. They are not approved for use in humans or animals, or for application in in vitro diagnostic procedures.
Upon receiving, directly and immediately transfer the cells from dry ice to liquid nitrogen and keep the cells in liquid nitrogen until they are needed for experiments.
Cells are only warranted if ScienCell media and reagents are used and the recommended protocols are followed.
