CRC Organoid Culture: A Method to Obtain 3D Organoids from Colorectal Cancer Cells
Overview
This video describes the detailed protocol for generating 3D organoids from murine-model derived colorectal cancer cells by propagating them on artificial extracellular matrix coated plates. These CRC organoids can be used as a model to study the primary growth of human tumor cells and metastasis.
Protocol
All procedures involving animals have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
1. Extraction of PDXs into the Cell Suspension for the CRC Organoid Culture
Experimental procedures for dissociation of CRC PDXs are outlined in Figure 1B (step 3).
- Place the tumor fragments derived from NOD/Shi-scid IL2Rγ null (NOG) mouse on a 10 cm Petri dish.
- Mi.......

The CRC tissue surgically dissected from the patient was cut into pieces and implanted subcutaneously into NOG mice. s.c.: subcutaneous implant.......
