| Strain： | C57BL/6 |
| Applications： | This cell linexa0is useful for the study of signal transduction of angiogenic factors. This cell linexa0is the only line known that can give rise to benign hemangiomas. xa0 |
| Storage Conditions： | liquid nitrogen vapor phase |
| Derivation： | MS1 is a pancreatic islet endothelial cell line established in 1994. Primary islet endothelial cells were transduced with a temperature sensitive SV40 large T antigen (tsA-58-3) constructed and screened for resistance to G418. Resistant colonies were isolated in cloning rings and screened for uptake of diI-Ac-LDL. |
| Receptor Expression： | vascular endothelial growth factor (VEGF), expressed |
| Genes Expressed： | tissue inhibitor of bioreactive matrix metalloproteinase (high levels) |
| Cellular Products： | tissue inhibitor of bioreactive matrix metalloproteinase (high levels) |
| Comments： | The line retains many properties of endothelial cells including uptake of acetylated LDL and expression of both Factor VIII related antigen and VEGF receptor. The expression of high levels of the tissue inhibitor of bioreactive matrix metalloproteinase makes the behavior of this cell line more like that of normal macrophages from some commonly used strains of mice. |
| 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 5%.
|
| Subculturing： | Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Subculture Ratio: 1:4 to 1:8 Medium Renewal: 2 to 3 times a week.
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.
