The CESS cell line is a B lymphoblastoid cell line derived from a human patient with leukemia. This cell line is commonly used to study immunoglobulin production, particularly IgG secretion, due to its strong response to cytokine stimulation. CESS cells are EBV-transformed and exhibit surface markers characteristic of mature B cells, such as CD19 and CD38. They express the sIgG1 class of immunoglobulins and serve as a model for studying B cell differentiation and function, including immune responses regulated by cytokines like interleukin-6 (IL-6), also known as B-cell stimulation factor 2 (BSF-2). IL-6 plays a crucial role in stimulating immunoglobulin production in CESS cells, making them a valuable model for investigating B cell responses in immunological research. Additionally, CESS cells have been instrumental in studies focusing on cell signaling and apoptosis. Notably, these cells have been shown to produce and respond to Nerve Growth Factor (NGF) through an autocrine signaling mechanism, expressing both high- and low-affinity NGF receptors. Blocking NGF signaling with antibodies or specific inhibitors induces apoptosis in CESS cells, characterized by Bcl-2 phosphorylation and activation of the p38 MAPK pathway. This makes CESS cells an important model for understanding the molecular mechanisms of B cell survival and apoptosis, particularly in the context of NGF signaling and its regulation of the Bcl-2 family proteins.

  • Viruses: Transformed by EBV
  • Products: IL-2 after induction with TRF (T cell-replacing factor)
  • cultureMedium: RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a)
  • supplements: Supplement the medium with 10% FBS
  • subculturing: Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.
  • seedingDensity: 1 x 104 cells/cm2 is recommended
  • fluidRenewal: 2 to 3 times per week
  • postThawRecovery: Allow the cells to recover from the freezing process for at least 48 hours.
  • freezeMedium: 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.
