Background of 293T-cyno-CDH3 Cell Line

Cadherin 3 (CDH3), also known as P-cadherin, is a calcium-dependent transmembrane cell-cell adhesion glycoprotein of the classical cadherin family. It is expressed in placental, basal epithelial and myoepithelial tissues, where it mediates adherens junctions, cell sorting and tissue architecture. CDH3/P-cadherin is upregulated in a subset of breast, lung, gastric, colorectal and other carcinomas, where its expression correlates with cancer stem-cell features, epithelial plasticity, invasion and adverse prognosis. As a cell-surface antigen with restricted normal-tissue distribution, CDH3 is being developed as a target for antibody-drug conjugates, T-cell-engaging bispecific antibodies and other precision cancer therapies, including conjugates designed to deliver cytotoxic payloads to CDH3-positive tumor cells.

Cell Line Generation

The 293T-cyno-CDH3 cell line was generated using a lentiviral vector expressing the cyno CDH3 sequence.

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 1:4–1:6 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.
