|I. General information|
|Background:||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 MG (formerly known as U-373 MG)’ and has the new ECACC catalogue number 09063001.
