CRL-2922 EA.hy926 人臍靜脈細胞融合細胞
Comments: The human umbilical vein cell line, EA.hy926, was established by fusing primary human umbilical vein cells with a thioguanine-resistant clone of A549 by exposure to polyethylene glycol （PEG）. Hybrid clones were selected in HAT medium and screened for factor VIII-related antigen. EA.hy926 cells have been maintained for more than 100 population doublings （PDLs）. Electron photomicrographs demonstrate cytoplasmic distribution of Weibel-Palade bodies and tissue-specific organelles, characteristics of differentiated endothelial cell functions such as angiogenesis, homeostasis/thrombosis, blood pressure and inflammation.

Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbeccos Modified Eagles Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10.
Atmosphere: air, 95; carbon dioxide （CO2）, 5
Temperature: 37.0°C
Subculturing: Protocol: Volumes used in this protocol are for 75 sq cm flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
1.Remove and discard culture medium.
2.Briefly rinse the cell layer with Ca++/Mg++ free Dulbeccos phosphate-buffered saline （D-PBS） or 0.25 （w/v） Trypsin - 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
3.Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed （usually within 5 to 15 minutes）.

Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37C to facilitate dispersal.
4.Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
5.Transfer cell suspension to a centrifuge tube and spin at approximay 125 X g for 5 to 10 minutes. Discard supernatant.
6.Resuspend the cell pellet in fresh growth medium. Add appropriate aliquots of the cell suspension to new culture vessels. An inoculum of 2 X 10（3） to 3 X 10（3） viable cells/sq. cm is recommended.
7.Incubate cultures at 37C. Subculture when cell concentration reaches between 8 X 10（4） and 1 X 10（5） cells/sq. cm.
Interval: Twice a week
Subc*tion Ratio: A subc*tion ratio of 1:6 to 1:10 is recommended
Medium Renewal: Every 2 to 3 days
Preservation: Freeze medium: Complete Growth medium, 95; DMSO, 5
Storage temperature: liquid nitrogen vapor phase
Related Products: Recommended medium （without the additional supplements or serum described under ATCC Medium）:ATCC 30-2002
