For 5 animals:
1. Thaw a single vial of 3,000,000 cells 2. Add to 9 ml of warmed 10% FBS DMEM 3. Spin at 1,000 RPM for 3 min 4. Discard supernatant 5. Resuspend to 10 ml 6. Plate this volume on a single 100 mm non-tissue culture treated petri dish 7. Place at 37*C (with 5% CO2) for 72 h 8. Recover the cells by pipetting and then ejecting the media onto the plate * repeat this twice and do it VERY GENTLY to ensure you don't disturb the clumps 9. Split 1:3 (put 1/3 volume back onto original plate, and the other 1/3 onto two new plates) 10. Bring the volume up to 10 ml with 10% FBS DMEM 11. Place at 37*C (with 5% CO2) for 24 h 12. Collect cells as in step 8 into 50 ml falcon tubes 13. Use an additional 5-10 ml of 10% FBS DMEM to pick up the remaining cells 13. Spin tubes at 1,000 RPM for 3 min 14. Discard supernatant, gently resuspend pellet by tapping 15. Combine resuspended pellets into a single ependorrf 16. Spin at 1,000 RPM for 1 min, discard supernatant, and bring up to final volume of approximately 150-200 ul 17. Gently tap the vial to resuspend the cells
Ensure viability of 60-80% using trypan blue. Use 25 ul of cells (+25 ul of cytokine) to perform intubations.
