MCF7 Cell Line

General Information
OrganismHomo sapiens, human
Cell Line DescriptionMCF-7 is a human breast cancer cell line which was first isolated in 1970 from the malignant adenocarcinoma breast tissue of a 69-year old woman. Cells exhibit some features of differentiated mammary epithelium including estradiol synthesis and formation of domes. Cells can carry B or C type retrovirus and are thought to represent a category 2 pathogen (P2 containment). Cells express the wild-type and variant estrogen receptors as well as progesterone receptor.

Culture Conditions and Handling
Subculturing

Volumes are given for a 75 cm2 flask. Proportionally increase or reduce the amount of dissociation medium for culture vessels of other sizes.

  1. Remove culture medium to a centrifuge tube.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
  3. Add 2.0-3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5-15 minutes). Cells that are difficult to detach can be placed at 37°C to facilitate dispersal.
  4. Add 6.0-8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  5. Transfer the cell suspension to the centrifuge tube with the medium and cells from step 1, and centrifuge at 125 x g for 5-10 minutes. Discard the supernatant.
  6. Resuspend the cell pellet in the fresh growth medium. Add appropriate aliquots of the cell suspension to new culture vessels.
  7. Incubate cultures at 37°C.
Subcultivation RatioThe ratio of 1:3 to 1:6 is recommended.
Fluid Renewal2 to 3 times per week
Freeze MediumComplete growth medium 95%; DMSO, 5%
Culture Temperature37°C
AtmosphereAir, 95%; carbon dioxide (CO2), 5%
