Background of 293T-LRP6-KO Cell Line

The Low Density Lipoprotein Receptor Related Protein 6 (LRP6) gene encodes a key co receptor in the Wnt signaling pathway, which plays a critical role in embryonic development, cell proliferation, and tissue homeostasis. LRP6, along with LRP5, forms a family of single pass transmembrane proteins that interact with Wnt ligands to activate the canonical Wnt/β catenin signaling cascade. This pathway is essential for regulating gene expression involved in cell fate determination, organogenesis, and metabolic processes. Mutations in LRP6 have been linked to various human diseases, including osteoporosis, coronary artery disease, and cancer, highlighting its importance in both normal physiology and pathology.

Cell Resuscitation

Prewarm culture medium (DMEM + 10% FBS) 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 1:4-1:8 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.
