<p class="jove_content">This minimally invasive method of establishing orthotopic bladder tumors in female mice can also be applied for cell types other than MB49, although differing results should be anticipated.  When less-aggressive tumor cells are used, increasing the wattage slightly (using 0.5 W increments to establish the new optimum) will yield an area more amenable to tumor cell attachment, and longer bladder incubation times for the instilled cells will yield a greater amount of cell attachment at the burn sites (unpublished data).

an orthotopic model of murine bladder cancer

<p class="jove_content">In this straightforward procedure, bladder tumors are established in female C57 mice through the use of catheterization, local cauterization, and subsequent cell adhesion.  After their bladders are transurethrally catheterized and drained, animals are again catheterized to permit insertion of a platinum wire into bladders without damaging the urethra or bladder.  The catheters are made of Teflon to serve as an insulator for the wire, which will conduct electrical current into the bladder to create a burn injury.  An electrocautery unit is used to deliver 2.5W to the exposed end of the wire, burning away extracellular layers and providing attachment sites for carcinoma cells that are delivered in suspension to the bladder through a subsequent catheterization.  Cells remain in the bladder for 90 minutes, after which the catheters are removed and the bladders allowed to drain naturally.  The development of tumor is monitored via ultrasound.  Specific attention is paid to the catheterization technique in the accompanying video.</p>
