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.

Rarely ever does a week go by in the Hermann lab without some new and exciting experimental results – a testament to the hard work and dedication by all of our staff and students. Ultimately, our hard work culminates in successful competition for grants and publication of manuscripts in scientific journals. Found below are lists of some significant news and milestones for the laboratory, as well as some links to professional societies and resources relevant to our research (and some that aren't so relevant, but definitely entertaining).

Science is nothing but trained and organized common sense differing from the latter only as a veteran may differ from a raw recruit: and its methods differ from those of common sense only as far as the guardsman's cut and thrust differ from the manner in which a savage wields his club.

– Thomas Henry Huxley (1825-95) English biologist

A few days after presenting her research at the Society for Study of Reproduction annual meeting in Montreal, Dawn Lovelace passed her qualifying exams and advanced to candidacy in the Cell and Molecular Biology PhD Program at UTSA. Congratulations Dawn!

June 27, 2013
The Hermann Lab is featured in an article by the San Antonio Express News detailing our participation in a summer research program funded by the Presidential Awards for Excellence in Science, Mathematics and Engineering Mentoring Program (PAESMEM) and UTSA College of Sciences. We welcomed Rose Joachim from UMass-Boston for the summer. Rose worked on our current Fertility Preservation research project.

December 15, 2012 – Lab Christmas Party
We had fun trying to unwrap a gift while impeded by oven mitts. Also, rather than just decorating gingerbread men, we decorated GFP+ colonies of spermatogenesis in SSC transplant recipient testes!
