| Receptor Expression |
estrogen receptor, negative progesterone receptor, negative |
| Oncogene |
her2/neu +, p53 - |
| Genes Expressed |
Epithelial glycoprotein 2 [EGP2]; cytokeratin 19 |
| Cellular Products |
Epithelial glycoprotein 2 [EGP2]; cytokeratin 19 |
| Comments |
The tumor was classified as TNM stage IIIA, grade 3, invasive ductal carcinoma with 5 out of 5 lymph node metastasis.?
The cells are poorly differentiated.?
The cells overexpress Her2-neu but are negative for expression of p53. HCC1419 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 for expression of progesterone receptor (PR).

| 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 10 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 1:3
Medium Renewal: 2 to 3 times a week.
Note: The line grows as large epithelial attached cells in island-like formation.
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 13 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 5th edition, published by Wiley-Liss, N.Y., 2005.
