The Hermann Lab

Our laboratory is part of the group of stem cell and developmental biologists at the University of Texas at San Antonio. We study the stem cell system underlying spermatogenesis which are essential for male fertility. A primary interest of the lab is understanding the fundamental biology of these spermatogonial stem cells, normal male germline development, and how stem cells might be used to regenerate spermatogenesis and promote animal transgenesis in nonhuman primates. We are also actively pursuing approaches to preserve fertility in prepubertal male cancer patients.

About Us

The Hermann Laboratory group is part of the Department of Neuroscience, Developmental and Regenerative Biology at the University of Texas at San Antonio. Established in July 2011, our laboratory group has grown from one lonely PI to a productive group of postdocs, students, and technicians. The lab is always buzzing with exciting experiments, humming equipment, and the chatter of busy scientists. We are also proud to be part of a growing group of UTSA investigators who share a common interest in stem cell biology. Our stem cell lab group meets regularly through the academic year to discuss research, journal articles, and critique funding applications.

Our research interests include the fundamental biology of spermatogonial stem cells in a variety of laboratory animal models, including rodents and non-human primates, as well as humans. We also use non-human primates for preclinical studies of spermatogonial stem cell transplantation and transgenesis in marmosets. Because of these interests, we are affiliated with the UTSA Institute of Regenerative Medicine (IRM), which biologypromotes collaborative research among scientists and engineers at UTSA and around San Antonio to address issues of health and disease from a regenerative medicine standpoint.

A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.
