Background
Leukemia cell lines are utilized as tools for molecular analysis. Their implementation in therapy will require standards for quality control, including appropriate selection criteria for functional analysis and efficacy determination. Materials and
Conclusion
Our study gives a useful guideline of standards for appropriate usage of leukemia cell lines for examining novel targets in vitro.
Methods
Characteristics of six human leukemia cell lines -Kasumi-1, NB-4, MOLM-13, MV-4-11, K562, and Jurkat cells-were investigated using multiple color analysis of surface antigen expression and comparative analysis of gene expression.
Results
Differentiation states of Kasumi-1 and MOLM-13 cells are colony-forming units-granulocyte/macrophage equivalent cells to myeloblasts with comparatively high Growth factor independent-1(GFI1) and Transcription factor PU.1 (PU.1) expression, respectively. NB4 and MV-4-11 express high levels of CCAAT/enhancer-binding protein-alpha (CEBPα) and differentiate from myeloblasts to pro-monocytes and myeloblasts, respectively. K562 cells are colony-forming units-erythroid equivalent cells to erythroblasts, with the highest expression of GATA-binding factor 2 (GATA2), GATA1 and Friend of gata-1 (FOG1). Jurkat cells are pro-T to mature T-cells with the highest Neurogenic locus notch-1 homolog protein 1 (NOTCH1) expression.
