| Disease： | malignant pluripotent embryonal carcinoma |
| Age： | 22 years |
| Gender： | male |
| Ethnicity： | Caucasian |
| Applications： | This cell line is a suitable transfection host. |
| Karyotype： | This is a hypotriploid human cell line with the modal chromosome number of 63 in 48% of cells examined. However, cells with 62 chromosome counts also occurred at a rather high frequency (24%). The rate of polyploidy was 1.6%., About 12 marker chromosomes are constantly found in most cells. They include: der(9)t(1;9)(q25;q34.3); del(1)(q25); der(13)t(11;13)(q13;q34); t(Xq1q); and eight others., At least two markers are found only in some cells. The normal Y chromosome was found in all cells. Only single copies of normal chromosomes 1, 10, 11 and 13 were present. Others were mostly in two or three copies per cell. |
| Derivation： | The parental NTERA-2 lines was established in 1980 from a nude mouse xenograft of the Tera-2 cell line (see ATCC HTB-106). The NTERA-2 cl.D1 cell line is a pluripotent human testicular embryonal carcinoma cell line derived by cloning the NTERA-2 cell line. |
| Clinical Data： | 22 years Caucasian male |
| Virus Resistance： | UNTREATED CELLS: human cytomegalovirus (HCMV); human immunodeficiency virus (HIV-1, HTLV-III) |
| Comments： | This clone differentiates along neuroectodermal lineages after exposure to retinoic acid (RA) or hexamethylene bisacetamide (HMBA). The RA induced differentiation is characterized by glycolipid changes, appearance of neurons, and induction of homeobox (HOX) gene clusters. The cells exhibit high expression of N-myc oncogene activity. To induce differentiation, the cells should be trypsinized and seeded at a density 1 X 10 exp6 cells per 75 sq. cm. in medium containing 0.01 mM trans-retinoic acid. Stock solutions of trans-retinoic acid (10 mM, dissolved in DMSO) should be stored frozen (preferably under a nitrogen atmosphere). |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Dulbeccos Modified Eagles Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
|
| Subculturing： | Subcultures are prepared by scraping. Cells from confluent cultures (approximately 20 million cells per 75 cm2) are dislodged from the flask surface, aspirated and dispensed into new flasks. Cultures should be maintained at high density. Seed new flasks at a density of at least 5 X 106 viable cells per 75 cm2 flask.
Medium Renewal: Every 2 to 3 days
