to keep the incision in the eardrum open without the need for tube insertion is application of a medication called mitomycin C, which was originally developed to treat bladder cancer. The mitomycin prevents the incision from sealing over.

For those who do not know, mitomycin finds use as a chemotherapeutic agent by virtue of its antitumour antibiotic activity. Mitomycin is a potent DNA crosslinker. A single crosslink per genome has shown to be effective in killing bacteria. This is accomplished by reductive activation, followed, by two N-alkylations. Because the chemical can cause genetic damage to bacteria, it is possible that mitomycin can also crosslink human DNA, resulting in genetic damage.

Mouse embryonic fibroblasts are inactivated by either chemical (Mitomycin-C) or radioactive (Cs-137) means before culturing with embyronic stem cells to prevent the fibroblasts from merging with the stem cells and creating a chimeric cell.
