The mammalian cerebellum is indispensable in the coordination of voluntary movement (i.e. balance and locomotion), muscular tonus and equilibrium. The cerebellar blood brain barrier (BBB) helps maintain the homeostasis of the cerebellum microenvironment and its integrity is often connected to many disorders of the central nervous system (CNS). The Immortalized Mouse Cerebellar Capillary Endothelial Cell Line (cerebEND) provides a useful model for studies involving the differentiation and regulation of BBB as it shares principal features of the BBB?n vivo, specifically in that 1) it retains endothelial markers VE-Cadherin and PECAM-1; 2) it displays tight junction associated markers such as occludin, claudin-3, -5, -12, 3) it expresses the BBB marker protein Glut-1 and 4) it shows high electrical resistance, representing barrier properties. This cell line is also responsive to glucocorticoid, estrogen-treatment and pro-inflammatory mediator such as TNF?, making this cell line valuable in elucidating cellular responses of endothelial cells to different stimuli. Compared to the Immortalized Mouse Cerebral Capillary Endothelial Cell Line (cEND), the cerebEND shows a higher fragility of the cerebellar BBB to inflammatory stimuli; together the two cell lines represent important model systems for these different brain regions.

Disclaimer
1. All test parameters provided in the CoA are conducted using abm's standardized culture system and procedures. The stated values may vary under the end-user's culture conditions. Please verify that the product is suitable for your studies by referencing published papers or ordering RNA (0.5 ?g, Cat.# C207, $450.00) or cell lysate (100 ?g, Cat.# C206, $600.00) to perform preliminary experiments, or alternatively use our Gene Expression Assay Service (Cat# C138). All sales are final. 2. We recommend live cell shipments for ease of cell transfer and this option can be requested at the time of ordering. Please note that the end-user will need to evaluate the feasibility of live cell shipment by taking into account the final destination's temperature variation and its geographical location. In addition, we thoroughly test our cell lines for freeze-thaw recovery. If frozen cells were received and not recovered in your lab under the exact, specified conditions (using recommended culture vessel, media, additional supplements, and atmospheric conditions), a live cell replacement is possible at a cost (plus shipping). 3. All of abm's cell biology products are for research use ONLY and NOT for therapeutic/diagnostic applications. abm is not liable for any repercussions arising from the use of its cell biology product(s) in therapeutic/diagnostic application(s).

Notes
1. Visually examine the packaging containers for signs of leakage or breakage. 2. Immediately transfer frozen cells from dry ice packaging to a temperature below -130?, preferably in liquid nitrogen vapor phase storage, until ready for use.To ensure the highest level of viability, thaw the vial and initiate culture as soon as possible upon receipt. If continued storage is desired, the vial should only be stored below -130? or in liquid nitrogen vapor phase. Do not store at -70?, as it will result in loss of viability.

Propagation
Use of PriCoatTMT25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. Grow cells inECM-coated culture vessels unless otherwise specified in the Propagation Requirements below.The base medium for this cell line is Prigrow III medium available at abm (TM003). To make the completed growth medium, add the following components to the base medium: heat-inactivated fetal bovine serum to final concentration of 10% and Penicillin/Streptomycin Solution (G255) to a final concentration of 1% Carbon dioxide (CO2): 5%, Temperature: 37.0
Cryopreservation
Cryopreservation Medium (TM024), or complete growth media with 10% DMSO.
Applications Range
Research Use Only.
Shipping
Ship with dry ice.

Product Use
This product is intended for laboratory research use only. It is not intended for any animal or human therapeutic use, any human or animal consumption, or any diagnostic use.
Storage
Vapor phase of liquid nitrogen, or below -130?.
Thawing Protocol
1. Thaw cells quickly in a 37? water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination. 2. Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions. 3. Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 125xg for 5-7 minutes. 4. Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask. 5. Incubate the cells at the recommended conditions.
Subculture Protocol
Volumes given below are for a T75 flask; proportionally increase or decrease the volume as required per culture vessel size. Subculture cells once the culture vessel is 80% confluent. 1. Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel. 2. Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37?, for several minutes to facilitate detachment. 3. Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel. 4. Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type. 5. Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired. 6. Incubate the cells at the recommended conditions.
