    Biosafety Level: 1
    Shipped: frozen
    Medium & Serum: See Propagation
    Growth Properties: adherent
    Organism: Homo sapiens
    Morphology: epithelial

    Source: Organ: mammary gland; breast
    Tissue: epithelium
    Disease: normal

    Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material.

    THO1: 9.3

    vWA: 18,19
    Cytogenetic Analysis: 45, XX
    Age: 21 years
    Gender: female
    Comments: The 184A1 cell line was established from normal mammarytissue obtained from a normal reduction mammoplasty.
    Cells derived from the tissue were exposed to benzo(a)pyrene, and a transformed line was established.
    The line appears to be immortal, but is not malignant.
    When seeded at low density, the cells grow as single cells.
    Propagation: ATCC complete growth medium: The base medium for this cell line (MEBM) along with the additives can be obtained from Lonza/Clonetics Corporation as a kit: MEGM, Kit Catalog No. CC-3150. ATCC does not use the GA-1000 (gentamycin-amphotericin B mix) provided with kit. To make the complete growth medium, you will need to add the following components to the kit (sold separately):
    • 0.005 mg/ml transferrin
    • 1 ng/ml cholera toxin
    Note: Do not filter complete medium
    Temperature: 37.0°C
    Subculturing: Protocol:
    • Remove and discard culture medium.
    • Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution.
    • 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 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 37�C to facilitate dispersal.
    • Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
    • To remove trypsin-EDTA solution, transfer cell suspension to centrifuge tube and spin at approximately 125 xg for 5 to10 minutes.Discard supernatant and resuspend cells in fresh serum-free growth medium. Add appropriate aliquots of cell suspension to new culture vessels.
    • Place culture vessels in incubators at 37�C.

    Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:6 is recommended
    Medium Renewal: Every 2 to 3 days
    Preservation: Culture medium, 75%; fetal bovine serum, 15%; glycerol, 10%
