Comments:
SVEC4-10 is an endothelial cell line derived by SV40 （strain 4A） transformation of endothelial cells from axillary lymph node vessels. These fully transformed small vessel murine endothelial cells were cloned in 1987 by limiting dilution. They grow indefiniy without special additives and are well differentiated, responding like normal endothelial cells to some interleukins and to extracellular matrix signals for tube-like differentiation. When grown on a synthetic basement-like membrane, SVEC4-10 forms branching tube-like networks. They specifically bind mouse lymphocytes in vitro. The cells express the cell surface major histocompatibility complex class I antigen, H-2 k, and are susceptible to lysis by anti SV40 H-2 k CTL clones. Interferon gamma （IFN-gamma） induces expression of MHC class II antigen in a time course identical to that of normal endothelial cells. The cells express vascular cell adhesion molecule （VCAM）, and stain positively for SV40 T antigen. Tumor necrosis factor alpha （TNF alpha） induces SVEC4-10 to undergo reversible transition to a spindle shaped morphology. SVEC4-10 is the parental line for a series of endothelial cell clones （ATCC CRL-2160, ATCC CRL-2161, ATCC CRL-2162, ATCC CRL-2163, ATCC CRL-2167, ATCC CRL-2168 and ATCC CRL-2171.
Propagation:
ATCC complete growth medium: Dulbecco's modified Eagle's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and 4.5 g/L glucose, 90%; heat-inactivated fetal bovine serum, 10% Temperature: 37.0°C Atmosphere: air, 95%; carbon dioxide （CO2）, 5%
Subculturing:
Subc*tion Ratio: A subc*tion ratio of 1:4 to 1:6 is recommended Medium Renewal: Every 2 to 3 days Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature （or at 37C） until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks.
