Background of CT26-GDF15-Cell-Line

GDF15, also named MIC-1, is a member of TGF-beta superfamily proteins, and plays an important role in tumorigenesis and metastasis. the expression of GDF-15 is dramatically increased in many types of cancers, such as colorectal, breast, and prostate. GDF-15 also mediates cancer-induced anorexia and weight loss through the modulation of neuronal pathways important in the regulation of appetite and energy homeostasis.

Cell Line Generation

CT26 human GDF15 Cell Line was generated using a retroviral vector expressing human GDF15 sequence.

Characterization

Cell Resuscitation

Prewarm culture medium (DMEM + 10% FBS + 10μg/mL Puromycin) in a 37°C water bath.
Thaw the frozen vial in a 37°C water bath for 1-2 minutes.
Transfer the vial into biosafety cabinet, and wipe the surface with 70% ethanol.
Unscrew the top of the vial and transfer the cell suspension gently into a sterile centrifuge tube containing 9.0mL complete culture medium.
Spin at ~ 125 × g for 5-7 minutes at room temperature, and discard the supernatant without disturbing the pellet.
Resuspend cell pellet with the appropriate volume of complete medium and transfer the cell suspension into a T25 culture flask.
Incubate the flask at 37°C, 5% CO₂ incubator.
Split saturated culture 1:4-1:10 every 2-3 days; seed out at about 1-3 × 10⁵ cells/mL.

Cell Freezing

Prepare the freezing medium (70% DMEM + 20% FBS + 10% DMSO) fresh immediately before use.
Keep the freezing medium on ice and label cryovials.
Transfer cells to a sterile, conical centrifuge tube, and count the cells.
Centrifuge the cells at 250×g for 5 minutes at room temperature and carefully aspirate off the medium.
Resuspend the cells at a density of at least 3×10⁶ cells/mL in chilled freezing medium.
Aliquot 1 mL of the cell suspension into each cryovial.
Freeze cells in the CoolCell freezing container overnight in a -80°C freezer.
Transfer vials to liquid nitrogen for long-term storage
