This video demonstrates a strategy to split and propagate spheroids developed from small bowel neuroendocrine tumor cells. These spheroids have small bowel neuroendocrine tumor markers and can be propagated and further used to test anti-cancer drugs.
Protocol
1. Splitting SBNET Spheroids NOTE: This is done for expansion and for sharing with other researchers. Use a P1000 pipette to mechanically break the ECM and aspirate the ECM with SBNET spheroids to a sterile 1.5 mL tube. Centrifuge at 1,000 x g at 4 °C, remove all the supernatant and place the tube on ice. Add 2-4x the volume of the new ECM to the pellet. Mix the new ECM with the old ECM and SBNET spheroid…
