| Karyotype |
CRL-2336 is highly transformed which is evident from the chromosome count and karyotype description. The modal chromosome number is 100. At least forty-three marker chromosomes, involving nearly every chromosome, were found. Chromosome 1 and chromosome 3 derivative chromosomes were verified using commercial whole chromosome paint (fluorescent in-situ hybridization (FISH)) probes. An acrocentric chromosome with an extra C-band at qter was detected (2 copies per metaphase). There were no normal X chromosomes however at least one derivative X was seen in each cell. The absence of a Y chromosome was verified by QM staining and C-bands. Normal copies of N1, N4, N15, N16 and N18 were absent. More detailed cytogenetic information is available upon request. |
| Derivation |
This cell line was initiated from a primary ductal carcinoma on October 13, 1995, and took 11.5 months to establish

| Clinical Data |
23 years adult An EBV transformed lymphoblastoid cell line (HCC1937BL) from the same patient is available as ATCC CRL-2337 BRCA1 analysis revealed that the cell line is homozygous for the BRCA1 5382C mutation, whereas the lymphoblastoid cell line derived from the same patient is heterozygous for the same mutation Caucasian female |

|
| Cellular Products |
Epithelial glycoprotein 2 (EGP2)

| Comments |
The tumor was classified as TNM Stage IIB, grade 3
BRCA1 analysis revealed that the cell line is homozygous for the BRCA1 5382C mutation, whereas the lymphoblastoid cell line derived from the same patient is heterozygous for the same mutation
This mutation was present in two other family members; an identical sister also developed breast cancer
The cell line has an acquired mutation of TP53 with wild-type allele loss; an acquired homozygous deletion of the PTEN gene, and loss of heterozygosity at multiple loci known to be involved in the pathogenesis of breast cancer
The cells are negative for expression of Her2-neu and for expression of p53.
HCC1937 is positive for the epithelial cell specific marker Epithelial Glycoprotein 2 (EGP2) and for cytokeratin 19
The cells are negative for expression of estrogen receptor (ER) and progesterone receptor (PR)
An EBV transformed lymphoblastoid cell line (HCC1937BL) from the same patient is available as ATCC CRL-2337

| Complete Growth Medium |
The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) 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.
- Remove and discard culture medium.
- 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.
- 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.
- Add appropriate aliquots of the cell suspension to new culture vessels.
- Incubate cultures at 37°C
Subculture Ratio: 1:2 to 1:4
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.
