Primary Human Brain Microvascular Endothelial Cells (ACBRI 376)⎢Cell Systems

Regular price $735.00

Primary Human Brain Microvascular Endothelial Cells (ACBRI 376) were initiated by elutriation of dispase dissociated normal human brain cortex tissue.

ACBRI 376 3 days after plating, plated with Attachment Factor™, fed using Cell Systems Complete Medium Kit With Serum and CultureBoost-R™ (4Z0-500-R)

Digital Fluorescence Images (direct flourescence 400X, indirect immunofluoresence 6300X) @ Passage 5


Digital Immunofluorescence ZO-1 mAb (6300X) @ Passage 5


Response to recombinant human IL-1ß stimulation in a PMN adherence assay @ P5 in vitro.

Cell Initiation

These cells were originated using Cell Systems Complete Serum-Free Medium (SF-4Z0-500), and subsequently grown and passaged in Cell Systems Complete Medium (4Z0-500). They are available at Passage 3 [< 12 cumulative population doublings] cryopreserved in Cell Systems Cell Freezing Medium™ (4Z0-705). This vial will initiate a Passage 4 cell culture in a 75cm2 flask.

In addition to cryopreserved vials, these cells also are available in 25cm2 and 75cm2 proliferating cell culture flasks (US domestic market only).

Additional Information

These cells are involved in the blood-brain barrier, HIV-Aids pathology, inflammation, and interact in vivo with astrocyte cells (ACBRI 371) and pericyte cells (ACBRI 499)

Functional Test: IL-1ß Stimulated Leukocyte Adherence 

Primary Brain Microvascular Cells can provide a useful tool for adherence, transport and permeability studies of the blood-brain-barrier (BBB).  ACBRI 376 cells demonstrate particular markers of differentiation (interdigitated cell contact, desmosomes, (Z0-1 protein epitopes) similar to those observed in vivo.  The morphological and immunofluorescent markers detailed for ACBRI 376 are suggestive of a differentiated cell monolayer that can be used to study properties of the human BBB.  These cells are extensively used in studies of HIV transmission and AIDS-related BBB dynamics.

In a functional test, ACBRI 376 monolayers in Cell Systems Serum-Free Medium were tested for IL-1ß stimulated leukocyte adherence.  Human leukocyte adherence was specific and dose-dependent as demonstrated by pretreatment of the microvascular monolayer with soluble IL-1ß receptor.  Nonspecific leukocyte adherence caused by phorbol ester was the positive control.  Polymorphonuclear leukocytes (PMN) were freshly isolated from peripheral blood by elutriation.
