Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Disease： | glioblastoma; classified as grade IV as of 2007 |
| Age： | 47 years |
| Gender： | male |
| Ethnicity： | Caucasian |
| Karyotype： | Hyperdiploid to pentaploid with several markers; the stemline chromosome number is near triploid with the 2S component occurring at 9.8%., Five markers t(11;5), t(8q;4), t(19;?18), M1 and M2 were common to most S metaphases. One chromosome 4 could be found in every S metaphase. Chromosome composition was very uniform among cells. |
| Derivation： | This is one of a number of cell lines derived from malignant gliomas (see also ATCC HTB-14 and ATCC HTB-15 ) by J. Ponten and associates from 1966 to 1969.xad |
| Clinical Data： | 47 years Caucasian male |
| Antigen Expression： | Blood Type A; Rh+ |
| Tumorigenic： | No |
| Effects： | No, in immunosuppressed mice Yes, in semisolid medium |
| Comments： | It differs from ATCC HTB-14 in morphology and it has a slower proliferation rate. Mycoplasma contamination was observed and cured by March 1974. NOTE: The two glioblastoma cell lines, U-118 MG (HTB-15) and U-138 MG (HTB-16), reportedly from different individuals have identical VNTR and similar STR patterns. U-118 MG and U-138 MG are very similar cytogenetically and share at least six derivative marker chromosomes. |
| 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： | Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 mL of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37°C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks.xa0xa0 Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended Medium Renewal: 2 to 3 times per week |
| Cryopreservation： | Culture medium, 95%; DMSO, 5% |
| Culture Conditions： | Temperature: 37°C
Atmosphere: air, 95%; carbon dioxide (CO2), 5% |
