| Comments： | This is a leukemic cell line with an 8;21 chromosome translocation. This translocation juxtaposes the AML1 with ETO (or MTG8) gene, giving rise to the fusion gene AML1-ETO (also known as AML1-MTG or RUNX1-CBF2T1), hence the cells produce chimeric AML1-ETO protein. This protein down-regulates CEBPA mRNA, protein and DNA binding activity, which is crucial for the differentiation of granulocytes. The cells are positive for myeloperoxidase showing a morphology of myeloid maturation.
In proliferation assay the cells in culture showed response to interleukin-3 (IL-3), IL-6, granulocyte colony-stimulating factor (G-CSF), and granulocytemacrophage CSF (GM-CSF), but not to IL-1 or IL-5. Neither granulocytic nor eosinophilic maturation was observed in the in vitro liquid culture by the addition of dimethyl sulfoxide, G-CSF, or IL-5, respectively. Induction of macrophagelike cells was seen by the addition of phorbol ester. Proliferation is inhibited by 1,25S-(OH)2-16,23-diene-26-F3-10-nor D3. |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 20%.
|
| Subculturing： | Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 3 x 105 viable cells/mL.
Interval: Maintain cell density between 3 x 105 and 3 x 106 viable cells/mL. Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density)
|
| Cryopreservation： | Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
