  • Induction of differentiation is a therapeutic approach for cancer
  • Treatment of leukemias with differentiation-inducing factors in combination with pro-apoptotic compounds has been shown to be highly effective
  • Ectopic expression of the transcription factor C/EBPα causes reprogramming of leukemia cells, resulting in expression of a normal cell phenotype
  • The BLaER1 cell line is a tamoxifen-inducible derivative of the RCH-ACV B-cell leukemia cell line genetically modified using a retrovirus vector to express C/EBPα fused with the estrogen receptor hormone binding domain (ER) and GFP
  • A study demonstrated that BLaER1 cells could efficiently convert into cells exhibiting increased adherent, phagocytic and quiescent properties with a transcriptome resembling normal macrophages
  • Cells retained their phenotype even when C/EBPα was inactivated, a characteristic of genuine cell reprogramming
  • C/EBPα induction also impaired cell tumorigenicity after transplantation into immunodeficient mice
  • BLaER1 is thus a model for highly efficient transdifferentiation of B-cell-derived human cancer cells
  • The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality
  • Cells are tested negative for infectious diseases by a Human Essential CLEAR panel by Charles River Animal Diagnostic Services
  • Cells are verified to be of human origin and negative for inter-species contamination from mouse, rat, Chinese hamster, Golden Syrian hamster, and non-human primate (NHP) as assessed by a Contamination Clear panel by Charles River Animal Diagnostic Services
  • Cells are negative for mycoplasma contamination
