In this video, we describe the intravesical procedure of delivering cancer cells into the bladder of a mouse model. This procedure helps generate an orthotopic bladder tumor model that can be used to develop therapeutic strategies.
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
1. Implanting the Tumor
NOTE: Each mouse is implanted with 1 x 105 MB49-PSA cells in 50 µL of DMEM blank media in the bladder. Due to the dead space in the catheter, always prepare extra volume (at least 100 µL extra per mouse). An alternative approach would be to use an air-filled syringe.
The authors have nothing to disclose.
