Background of Ba/F3-DDR1 Cell Line

DDR1 encodes discoidin domain receptor tyrosine kinase 1 and is also known as CAK. Receptor tyrosine kinases play a key role in the communication of cells with their microenvironment. These kinases are involved in the regulation of cell growth, differentiation and metabolism. The protein encoded by this gene belongs to a subfamily of tyrosine kinase receptors with homology to Dictyostelium discoideum protein discoidin I in their extracellular domain, and that are activated by various types of collagen. Expression of this protein is restricted to epithelial cells, particularly in the kidney, lung, gastrointestinal tract, and brain. In addition, it has been shown to be significantly overexpressed in several human tumors. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

Cell Resuscitation

  1. Pre-warm complete culture medium (basal medium and 10% FBS) in a 37°C water bath.
  2. Rapidly thaw the cryovial in a 37°C water bath for 1-2 minutes with gentle agitation.
  3. Transfer the vial to a biosafety cabinet, and disinfect the exterior with 70% ethanol.
  4. Aseptically transfer the cell suspension dropwise into a sterile centrifuge tube containing 9.0 mL of pre-warmed complete medium.
  5. Centrifuge at approximately 125 × g for 5–7 minutes at room temperature, carefully aspirate the supernatant without disturbing the cell pellet.
  6. Gently resuspend the pellet in an appropriate volume of complete medium and transfer the suspension into a T25 flask.
  7. Incubate the flask in a 37°C in a humidified 5% CO₂ incubator.
  8. Assess cell viability and morphology after 24 hours. If cells appear healthy, replace the medium with fresh medium supplemented with the appropriate selective antibiotic.
  9. Subculture the cells at a ratio of 1:10 every 2–3 days upon reaching 80%–90% confluency.

Cell Freezing

  1. Prepare the freezing medium (70% basal medium, 20% FBS and 10% DMSO) freshly before use.
  2. Pre-chill the freezing medium on ice and label the cryovials accordingly.
  3. Transfer the cell suspension to a sterile conical tube and perform a cell count to determine total viability and density.
  4. Centrifuge the cells at 250×g for 5 minutes at room temperature; carefully aspirate the supernatant.
  5. Gently resuspend the pellet in chilled freezing medium, ensuring a minimum cell density of 3×10⁶ cells/mL.
  6. Aliquot 1 mL of the cell suspension into each pre-labeled cryovial.
  7. Place the cryovials into a CoolCell® container and store at -80°C overnight for controlled-rate cooling.
  8. Transfer the cryovials to the liquid nitrogen for long-term storage the following day.
