Origine de la lignée cellulaire

Human erythroleukaemia

Description de la lignée cellulaire

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.

Application

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]

Questions

1–7 of 7 Questions  

  1. Why is Vapor Phase Liquid Nitrogen preferred for storage of Cell Line cells?

    1 answer

    1. If ampules are immersed into liquid phase of liquid nitrogen, it increases the risk of the liquid seeping into the vial. This could lead to problems of cross-contamination and increased risk of the ampule exploding when thawed.

      Helpful?

  2. How many Cell Line cells are in the vial?

    1 answer

    1. Each vial of cells contains 2-3 x 106 cells in 1 ml of freezing media. This is in a 1.8 mL ampule.  For exceptionally large cells, counts may decrease. Suspension cells, generally smaller cells, may contain as many as 4-5 x 106 cells/vial to assure optimal viability upon thaw.

      Helpful?

  3. Are the Cell Line cells tested for viral pathogens?

    1 answer

    1. HPA Cultures does not perform any viral testing on the cell lines.

  4. What medium should I use when I thaw the Cell Line cells?

    1 answer

    1. The medium for each cell line is listed on the product page. It is specific to each cell line. If not visible on the Sigma-Aldrich website product page, the HPA website also contains the same information (www.hpacultures.org.uk). The product number for the cell line is the same on either site.

      Helpful?

  5. How do I handle Cell Line frozen cells upon arrival?

    1 answer

    1. Upon receipt, frozen ampules should be transferred directly to vapor phase liquid nitrogen without delay (-135°C) or liquid phase liquid nitrogen if vapor phase is not available. DO NOT use a -80°C freezer as an alternative; this will result in loss of viability.

      Helpful?

  6. Are my Cell Line cells mycoplasma tested?

    1 answer

    1. ECACC routinely tests all manufactured cell banks for mycoplasma.

      Helpful?

  7. What passage are my Cell Line cells?

    1 answer

    1. If the passage of the cells is known, it is listed on the product page at the HPA website (www.hpacultures.org.uk).
