| Disease： | medulloblastoma |
| Age： | 6 years juvenile |
| Gender： | male |
| Ethnicity： | Caucasian |
| Storage Conditions： | liquid nitrogen vapor phase |
| Karyotype： | The karyotype is 45, XY, -7, -8, -17, -20, der(20)t(1;20)(q12;q13), 8q+, 17p+ (range = 41 to 46). This is a hypodiploid cell line with a frequency of higher ploidies of 5.4%. Three marker chromosomes are present in all cells. They are: der(20)t(1;20)(q12;q13), 8q+ and 17p+. N7, N17 and N20 have single copies. The single X is structurally normal, and the Y chromosome is present as confirmed by fluorescence microscopy. |
| Derivation： | The D283 Med cell line was established in 1985 by Friedman et al. from malignant ascites cells and a peritoneal metastasis from a boy with medulloblastoma. xad Derived from metastatic site, peritoneum |
| Clinical Data： | 6 years juvenile Caucasian The D283 Med cell line was established in 1985 by Friedman et al. from malignant ascites cells and a peritoneal metastasis from a boy with medulloblastoma. male |
| Genes Expressed： | The cells produce tumors in nude mice, and the resulting tumors are positive for expression of neurofibrillary proteins, glutamine synthetase and neuron specific enolase but negative for glial fibrillary acidic proteins and S100 (S-100) protein. The cells express elevated levels of four biochemical markers of SCLC (neuron specific enolase, the brain isoenzyme of creatine kinase, L-DOPA decarboxylase and bombesin-like immunoreactivity. |
| Cellular Products： | neurofilament proteins (NFP) |
| Tumorigenic： | Yes |
| Effects： | Yes, in nude mice (The cells form serially transplantable intercranial and subcutaneous tumors.) Yes, in soft agar |
| Comments： | The cells produce tumors in nude mice, and the resulting tumors are positive for expression of neurofibrillary proteins, glutamine synthetase and neuron specific enolase but negative for glial fibrillary acidic proteins and S100 (S-100) protein. |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Eagles Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
|
| Subculturing： | Cultures can be maintained by addition or replacement of medium. Adherent cells can be dislodged by scraping, and cultures can be established by resuspending a cell pellet at 5 X 105viable cells/mL. Maintain cultures between 4 X 105 and 1 X 105 cells/mL.
Medium Renewal: 2 to 3 times per week |
