BLaER1 Human B-cell Precursor Leukemia Cell Line
BLaER1 human B-cell precursor leukemia cell line may be transdifferentiated and used to model human monocytes.

General description
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/EBPa 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/EBPa 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/EBPa was inactivated, a characteristic of genuine cell reprogramming. C/EBPa 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.

Source:
BLaER1 cells are a single subclone isolated from C/EBPaER-GFP-transfected RCH-ACV acute lymphoblastic leukemia (ALL) cells sorted for GFP expression. The parental cell line was obtained from the bone marrow of a female with chromosome translocation 1;19 and trisomy 8 .

Biosafety Level 2:
BLaER1 cells contain squirrel monkey retrovirus (SMRV) and should be handled under biosafety level 2.
