Derivation
This breast tumor line was established by E.Y. Lasfargues and L. Ozzello in 1958 by isolation and cultivation of cells spilling out of the tumor when it was cut in thin slices. ­
Clinical Data
Caucasian
female
74 years
Antigen Expression Antigen expression: HLA A1, Bw16 (+/-)
Tumorigenic Yes
Effects
Yes, in nude mice
Comments
The cells express the WNT3 and the WNT7B oncogenes [PubMed: 8168088].
A mycoplasma contaminant was discovered and eliminated early in 1972.
Growth of BT-20 cells is inhibited by tumor necrosis factor alpha (TNF alpha).
BT-20 cells are negative for estrogen receptor, but do express an estrogen receptor mRNA that has deletion of exon 5.
Complete Growth Medium The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. 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 are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that 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.
