Sigma-Aldrich Product Name TF1 Cell Line human, 93022307, Erythroleukemic cell line from blood.

Human erythroleukaemia

TF-1 have been derived from a patient with erythroleukaemia. They show complete growth dependency on GM-CSF or IL-3, and carry a homogeneous chromosomal abnormality (54,X). Constitutive expression of globin genes indicate commitment of TF-1 to the erythroid lineage, although glycophorin A or carbonyl anhydrase I are not expressed. On incubation with hemin or delta-aminolevulinic acid haemoglobin synthesis was induced, whereas TPA induced differentiation into macrophage-like cells. Erythroprotein also sustains short-term growth, but does not induce differentiation.

TF1 cell line has been used-

• for tumorigenic studies
• to study the effect of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) on proliferation and TNFR2 expression in TF1 cells[1]
• in a cell-based proliferation assay to study the biological activities of anti-IL-6R Nanobody ALX-0061[2]
• to study the induction of STAT5 phosphorylation by IL-3[3]
