Cytogenetic Analysis: 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.
Age: 23 years adult
Gender: female
Ethnicity: Caucasian
Comments: This cell line was initiated from a primary ductal carcinoma on October 13, 1995, and took 11.5 months to establish
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
Propagation: ATCC 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%.
Temperature: 37.0°C
Subculturing: Protocol: Remove medium, rinse with 0.25% trypsin, 0.03% EDTA solution, add an additional 1 to 2 ml of trypsin solution and allow the flask to set at room temperature （or incubate at 37C） until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks.
Subc*tion Ratio: A subc*tion ratio of 1:2 to 1:4 is recommended
Medium Renewal: Every 2 to 3 days
Preservation: Freeze medium: Complete growth medium 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
