| Karyotype | This is a pseudo-diploid cell line of female origin with a modal chromosome count of 46 and a low-to-moderate rate of polyploidy. However, even though the line generally has 46 chromosomes per cell, several of those 46 were derivative or marker chromosomes. There were two copies of a karyotypically normal X-chromosome present in 50-60% of the cells. Other features included a normal variation in the heterochromatic region of chromosome 1 (1qh+), a consistent derivative-10 marker chromosome (present in most cells) and 2 other markers: del(3)(p24?) and del(16)(q21~23?) (present in approximately 20-30% of the analyzed cells). Overall, approximately 3-8 marker chromosomes were present in the analyzed metaphase spreads and satellite associations appeared sporadically. |

| Derivation | Human mammary epithelium, HME1 cell line, was derived from a 53-year-old patient undergoing reduction mammoplasty surgery (no history of breast cancer). The HME1 cells were immortalized by infection with the retrovirus pBabepuro+hTERT vector and cultured in complete growth medium containing puromycin until stable clones were selected. |
| Antigen Expression | Positive for the cytokeratin epithelial marker (immunocytochemistry) and for the Mucin 1, transmembrane (MUC1) protein (Homo sapiens; detection by flow cytometry). |
| Complete Growth Medium | The base medium for this cell line (MEBM) along with all the additives can be obtained from Lonza/Clonetics Corporation as a kit: MEGM, Kit Catalog No. CC-3150. ATCC does not use the GA-1000 (gentamycin-amphotericin B mix) provided with kit.
Note: Do not filter complete medium
|
| Subculturing | Volumes are given for a 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:6 is recommended.
Medium Renewal: Every 2 to 3 days
Note:For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 12 in Culture of Animal Cells: A Manual of Basic Technique by R. Ian Freshney. |

| Population Doubling Level (PDL) | As part of our quality control, we have tested this cell line for its ability to grow for a minimum of 15 population doublings after recovery from cryopreservation. We have also compared its karyotype, telomerase expression level, growth rate, morphology and tissue-specific markers when first recovered from cryopreservation with that of cells at 10+ population doublings to ensure that there is no change in these parameters and that the cells are capable of extended proliferation. |
