Karyotype Chromosome number range = 65 to 71 (Pauley RJ, et al. Immortal human mammary epithelial cell sublines. US Patent 5,206,165 dated Apr 27 1993)
Derivation The MCF-12A cell line is a non-tumorigenic epithelial cell line established from tissue taken at reduction mammoplasty from a nulliparous patient with fibrocystic breast disease that contained focal areas of intraductal hyperplasia. The line was produced by long term culture in serum free medium with low Ca++ concentration. MCF-12A was derived from adherent cells in the population.
Clinical Data 60 years adult Caucasian female
Genes Expressed epithelial mucin, milk fat globule membrane antigen, sialomucin
Cellular Products epithelial mucin milk fat globule membrane antigen sialomucin
Tumorigenic No
Effects No, in immunosuppressed mice Yes, in semisolid medium.
Comments MCF-12A cells exhibit typical luminal epithelial morphology, three dimensional growth in collagen, and form domes in confluent cultures.

The cells are positive for epithelial cytokeratins 8, 14 and 18, and negative for cytokeratin 19.

Cells derived from a floating population are available (see MCF-12F, ATCC CRL-10783).

 

Complete Growth Medium A 1:1 mixture of Dulbecco's modified Eagle's medium and Ham's F12 medium, 20 ng/ml Human epidermal growth factor, 100 ng/ml cholera toxin, 0.01 mg/ml bovine insulin and 500 ng/ml hydrocortisone, 95%; horse serum, 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.

  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.03% (w/v) EDTA solution to remove all traces of serum which contains trypsin inhibitor.
  3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually with 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 37°C to facilitate dispersal.
  4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. 
  5. To remove trypsin-EDTA solution, transfer cell suspension to   centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes.
  6. Discard supernatant and resuspend cells in fresh culture medium.  Add appropriate aliquots of cell suspension to new culture vessels. 
  7. Place culture vessels in incubators at 37°C.
