Description

Origine de la lignée cellulaire

Human glioblastoma astrocytoma

Description de la lignée cellulaire

Derived from a malignant glioblastoma tumour by explant technique. U-251 was formerly distributed as U-373 MG (Sigma product no. 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 (Sigma product no. 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 product no. 89081403 has been re-named as ′U-251 (formerly known as U-373 MG)′ and has the new Sigma product no. 09063001.

Application

U-251 MG cell line human has been used:

• for the extraction of cancer stem cells from U-251 human glioblastoma cell line
• to study the mechanism of Pax6 (paired box protein)-associated increase in expression of Dkk3 (Dickkopf 3)
• to study the role of JARID1B (jumonji AT-rich interactive domain 1B) in the pathogenesis of glioma
• to study the therapeutic efficacy of Irinophore C combined with temozolomide in glioblastoma tumor model
