Abstract

Transgenic mice are useful tools for studying gene function and regulation but can be difficult to successfully breed. To 'rescue' transgenic lines that are difficult to propagate, researchers use a variety of techniques. One method is ovarian transplant, in which researchers remove ovaries from a donor transgenic mouse, cryopreserve the ovarian tissue, transplant this tissue into histocompatible female mice and breed these recipient females. Though it is a useful technique, cryopreservation can potentially damage ovarian tissue, which could reduce fertility. In this article, the authors describe how they carried out ovarian transplants without cryopreservation to rescue a line of transgenic C57BL/6 mice. Other researchers who have experience with mouse reproductive surgery should be able to use this technique to rescue infertile transgenic lines of mice.
