"New research from scientists at Huntsman Cancer Institute (HCI) at the University of Utah and collaborators at University of Utah Health (U of U Health) sheds light on the complex process that occurs in the development of human sperm stem cells. This is the first study to characterize the changes human sperm stem cells undergo as they mature. The results have implications for understanding male infertility as well as cancer development and were published in the journal Cell Stem Cell.
Previous studies of sperm stem cells have been limited to model systems, including mice. But this first study of developing human sperm stem cells revealed this process was much more complex in humans than had been previously understood. Using genome analysis tools, scientists outlined the multistage process that sperm stem cells undergo during their normal development.
"This information yields new insights into how sperm stem cells function and develop under normal circumstances," says the study's lead author Bradley Cairns, PhD, senior director of basic science at HCI and professor and chair of oncological sciences at the U of U. "We have built a very important framework we can now use to help us understand what happens when things go wrong, resulting in issues like infertility and cancer in men..."
