Background of HEK293T-mouse-TF-Cell-Line

TF, also known as CD142, is a type I transmembrane glycoprotein, which is expressed on the surface of a variety of cells that are physically separated from the circulating blood which include smooth muscle cells, fibroblasts, keratinocytes, glomerular epithelial cells (cytoplasmic inclusions), astrocytes, myocardium, liver stromal cells, pancreas cells, and is also expressed on activated monocytes and stimulated endothelial cells. TF is a high-affinity receptor for coagulation factor VII and initiates the extrinsic pathway of blood coagulation. TF also plays an important role in a variety of diseases such as sepsis, atherosclerosis, and cancer.

Cell Line Generation

293T mouse TF cell line was generated using a lentiviral vector expressing the mouse TF sequence.

Characterization

Cell Resuscitation

Prewarm culture medium (DMEM + 10% FBS + 1μg/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 1:3-1:6 every 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
