In this video, we demonstrate a technique to isolate whole crypts from a mouse’s small intestine. The isolated whole crypts can be used to propagate long-lived and self-renewing 3D organoids in vitro.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Preparation of Instruments, Culture Media, and Dishes Autoclave one set of intestinal scissors, normal scissors, and forceps in a sterile container. Place a 96-well (flat bottom) dish in an incubator at 37 °C. Prepare 10 mL of complete culture medium with the reagents listed in the Table…
