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.

Primary Human Brain Microvascular Endothelial 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.

ACBRI 376 Primary Human Brain Microvascular Endothelial Cells 

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

ACBRI 376 cells express endothelial cell markers including CD31 and von Willebrand Factor. They also take up DiI-Ac-LDL in an endothelial cell functional assay.

ACBRI 376 cells express ZO-1 indicating the formation of tight junctions.

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. Each vial contains more than 1 x 10cells.

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

Companion Products

Each vial of cells is shipped with vials of Bac-Off® (antibiotic) and CultureBoost™ (animal derived growth factors) or CultureBoost-R™ (human recombinant growth factors) at no additional cost.

These cells are qualified for use with:

(A) HBMVECs (ACBRI 376) were cultured on Matrigel coated plates in EBM, EGM, or EBM supplemented with U87-GFP cells. Scale bar  = 450 µm. Inhibition of EZH2 in HBMVECs, either by transfection with pre-miR-101, EZH2 siRNA, or treatment with DZNep significantly reduced tubule formation as compared to control cells. Tubule formation was assessed as tubule length and branching. (B) Quantitation of tubule length and branching using ImageJ software. (n = 3) Error bars indicate s.d. *p<0.05, ***p<0.001, t test.

(A) HBMVEC (ACBRI 376) monolayer cultures were scratched. Images were acquired directly after scratching (t = 0) and 24 h later (t = 24). The migration front is indicated by the dashed lines. Scale bar  = 450 µm. Inhibition of EZH2 in HBMVECs, either by transfection with pre-miR-101, EZH2 siRNA or treatment with DZNep significantly reduced migration as compared to control. (B) Quantitation of endothelial cell migration into the scratched area using ImageJ software. (C and D) HBMVECs were transfected with pre-miR-101, EZH2 siRNA, non-related control molecules, or treated with DZNep, incubated on a Transwell system and subsequently analyzed for invasion capability. EZH2 inhibition, either through pre-miR-101, EZH2 siRNA or DZNep, significantly decreased invasion as shown by Hoechst staining. Scale bar  = 225 µm. (n = 3) Error bars indicate s.d. *p<0.05, ***p<0.001, t test.
