Cytogenetic Analysis:
|
This is a hyperdiploid (modal number = 49; range = 44 to 50) human cell line with higher ploidies occurring with a frequency of 8.5%. Four marker chromosomes are present in all cells. They are: 11HSR, i(17q), der(22)t(1;22)(q12;p12) and 8q-. There are three copies each of N6 and N18, and single copies each of N11, N17 and N22. The single X chromosome was structurally normal, and the presence of the Y chromosome was confirmed by fluorescence microsopy.

Comments:
|
The D341 Med cell line was established in 1988 by Friedman et al. from tumor tissue taken from a boy with medulloblastoma.
The cells produce tumors in nude mice.
The cell line is positive forexpressionof neurofibrillary proteins, glutamine synthetase and neuron specific enolase but negative for glial fibrillary acidic proteins and S100 (S-100) protein.
The cells are positive for the neuroectodermal antigen recognized by the UJ13A monoclonal antibody.
The c-myc oncogene is amplified in D341 Med cells.

Propagation:
|
ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Eagle's 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 20%.
Temperature: 37.0°C
|
Subculturing:
|
Protocol: 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 10(5) viable cells/ml. Maintain cultures between 4 X 10(5) and 1 X 10(6) cells/ml.
Medium Renewal: 2 to 3 times per week
|
Preservation:
|
Freeze medium: culture medium, 90%; DMSO, 10%
Storage temperature: liquid nitrogen vapor phase
