Karyotype This is a hyperdiploid human cell line. The modal chromosome number is 52, occurring at 40% with polyploidy at 3.8%., Over 2/3 of the chromosome complement consist of those with structural rearrangements (or markers) including 1q, t(1p,16q), del(3)(p13), t(5;14)(q35;q11), t(9q;?)1, t(9q;?)2, 12p+, 20p+, t(Xq,7p)., Twenty-one other markers are common to most cells. The normal chromosomes 1,3,5,9,14,15 and X are absent. All three E group chromosomes are paired., Y chromosome not detected by Q staining.
Genes Expressed
hCG; human chorionic gonadotropin (alpha subunit only); estradiol; progesterone; mucin (apomucin, MUC-1, MUC-2)
Cellular Products
hCG; human chorionic gonadotropin (alpha subunit only); estradiol; progesterone; mucin (apomucin, MUC-1, MUC-2)
Comments
The cells produce high levels of MUC-1 mucin mRNA, low levels of MUC-2 mRNA but do not express the MUC-3 gene.
Complete Growth Medium The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
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-0.53mM 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 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.
  4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
  6. Incubate cultures at 37°C.

Subcultivation Ratio: 1:4 to 1:6
Medium Renewal: Every 2 to 3 days

Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a Manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.

Cryopreservation Culture medium, 95%; DMSO, 5%. Cell culture tested DMSO is available as ATCC Catalog No. 4-X.
