Comments:
The M4A4 LM3-2 GFP (CRL-2916x99) was derived from a second generating lung metastasis after inoculation of M4A4 GFP cells in a nude mouse mammary gland. M4A4 LM3-4 CL 16 GFP (ATCC CRL-2917x99) cell line was established from a third generation lung metastasis. The M4A4 GFP (ATCC CRL-2915x99) was developed by the transduction of the GFP gene into M4A4 (CRL-2914x99) cell line. The parental cell lines xa0ATCC CRL-2914x99 (M4A4) and ATCC CRL-2918x99 (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.
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.
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%.
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.
  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 1.0 to 2.0 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 approximately 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 3 X 10(3) to 5 X 10(3) viable cells/sq. cm is recommended.
  7. Incubate cultures at 37C. We recommend that you maintain cultures at a cell concentration between 2 X 10(5) and 3 X 10(5) cells/sq. cm.
