Description	The Kasumi-1 cell line was derived from the peripheral blood of a 7-year-old Japanese boy with acute myeloid leukemia (AML), specifically the FAB M2 subtype, during a relapse following bone marrow transplantation. This cell line is a valuable resource for researchers studying hematologic malignancies, especially those involving the t(8;21) chromosomal translocation. This translocation leads to the formation of the AML1-ETO fusion gene, a critical factor in certain subtypes of AML. Kasumi-1 cells thus serve as an essential model for investigating the molecular mechanisms of AML and testing potential therapeutic approaches. Kasumi-1 cells possess characteristics of both myeloid and macrophage lineages, making them particularly useful for studies on myeloid differentiation. These cells can be induced to differentiate into macrophage-like cells when cultured with phorbol 12-myristate 13-acetate (TPA), providing a robust system for exploring the pathways involved in myeloid lineage commitment and differentiation. This differentiation capacity enhances the utility of Kasumi-1 cells in research focused on both AML biology and broader myeloid cell development processes.

Culture Medium	RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a)
Doubling time	40 to 45 hours
Subculturing	Maintain cultures by periodically adding or replacing the medium. Initiate cultures with a density of 2 x 10^5 cells/ml and keep the cell concentration within the range of 1 x 10^5 to 1 x 10^6 cells/ml for optimal growth.
Split ratio	A ratio of about 1:2 to 1:3 every 3 to 4 days is recommended
Seeding density	1 x 10^5 cells/ml
Fluid renewal	Add fresh medium (20 to 30% by volume) every 2 to 3 days
Freeze medium	As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.

Sterility	Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.
