|Keywords:||Human glioblastoma astrocytoma|
|Cell Line Description:||
Derived from a malignant glioblastoma tumour by explant technique. U-251 was formerly distributed as U-373 MG (ECACC catalogue number 89081403) until short tandem repeat (STR)-PCR profiling confirmed identity with U-251. A new deposit of U-373 MG known as U-373 MG (Uppsala) is now available (ECACC catalogue number 08061901).
Background to the identity query for the cell line U-373 MG: The American Type Culture Collection (ATCC) reported that their stock of U-373 MG had been shown to have differing genetic properties to stock from the originator’s laboratory, and to share similarities with another glioblastoma cell line, U-251. In light of this, ECACC undertook an investigation into the authenticity of its own stock of the U-373 MG cell line. ECACC found similar results to the ATCC i.e. the stock held as U-373 MG was found to be identical by STR-PCR profiling to U-251. The U-373 MG cell line listed under catalogue number 89081403 has been re-named as ‘U-251 (formerly known as U-373 MG)’ and has the new ECACC catalogue number 09063001.

Unless specified otherwise, at the European Collection of Authenticated Cell Cultures (ECACC) we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines. ACDP = Advisory Committee on Dangerous Pathogens (UK)
All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country.

The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.
Cultures supplied by Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line.
