the study of human and animal disease may be a little easier in the future, thanks to a breakthrough in Guelph's Animal Biotechnology Embryo Laboratory (ABEL) in the Department of Biomedical Sciences.
PhD Student Nucharin Songsasen, working with supervisor Prof. Stanley Leibo, has developed a simple and reliable method to freeze mouse semen. The reasons mouse spermatozoa is so difficult to freeze are only partly known, but may have to do with the peculiar long, hooked shape and sensitive membrane of these cells.
This development was an international imperative for researchers studying transgenic mice. These are mice that carry foreign genes on their chromosomes.
