| Derivation | M4A4 GFP was developed by the transduction of the GFP gene into M4A4 (ATCC CRL-2914?) cell line.
Note: Recent studies have generated questions about the origin of the parent cell line, MDA-MB-435. Gene expression analysis of the cells produced microarrays in which MDA-MB-435 clustered with cell lines of melanoma origin instead of breast. Additional studies have since corroborated a melanocyte origin of MDA-MB-435, to which ATCC has responded by pursuing its own investigation into the identity of this cell line. The cell line to which MDA-MB-435 is reported to have been cross-contaminated with is the M14 melanoma line. |

| Comments | The M4A4 GFP (CRL-2915?) was developed by the transduction of the GFP gene into M4A4 (ATCC CRL-2914?) cell line. One of the isolated cell lines, M4A4 LM3-2 GFP (ATCC CRL-2916?) was derived from a second lung metastasis. M4A4 LM3-4 CL 16 GFP (ATCC CRL-2917?) cell line was derived from a third generation lung metastasis after inoculation of M4A4 GFP cells in a nude mouse mammary gland.
The parental cell lines ATCC CRL-2914? (M4A4) and ATCC CRL-2918? (NM2C5) were derived from the human breast cancer cell line, MDA.MB-435. M4A4 is highly metastatic in immuno-deprived mice, while NM2C5 is weakly or virtually non-metastatic. These well characterized, tumorigenic human isogenic cell lines have dramatically opposite metastatic phenotypes and are ideal for metastatic studies.

| Complete Growth Medium | The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's 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%.
|
| Subculturing | Protocol: To avoid phenotypic drift it is recommended to make frozen aliquots of the cells and use each aliquot for only 10 passages. Note: If more than 5-10% non-fluorescing cells reappear at any time it is recommended to use 600 micrograms/mL G418 for 2-4 weeks to kill off the revertants. Resistance to higher concentrations of G418 depends on the number of copies of the neo resistance gene that the cell has incorporated which is not uniform for the whole population. 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.
Subcultivation Ratio: A subcultivation ratio of 1:20 to 1:40 is recommended Medium Renewal: 2 to 3 times a week |
