Bladder Tumor Organoid Model: A Method for Orthotopic Transplantation of Bladder Organoids into Recipient Murine Bladder
Overview
In this video, we describe the orthotopic transplantation of cultured bladder tumor organoids into the murine bladder to study the role of the organ environment on developing tumors.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
1. Subculture Bladder Tumor Organoids
NOTE: Passage of bladder tumor organoids when they reach 100–150 µm in diameter is recommended.
- Add 500 µL of collagenase/dispase to the organoid medium in a 24-well plate with tumor organoids. Pipette up and down th.......
