Germ Cells
In the adult mouse testis, all germ cells are labeled with DAZL (green) while only the undifferentiated germ cells express YBX1 (red). All cell nuclei are labeled with DAPI (blue). Image from MGDB Alum Bart Phillips, from Dr. Orwig's lab.

The Molecular Genetics and Developmental Biology (MGDB) graduate program provides an exceptionally exciting and vigorous academic environment for highly motivated and qualified students to prepare for a rewarding career in biomedical research.  The members of the faculty have a wide diversity of interests and are pursuing research projects that address fundamental, contemporary issues in biology and medicine.  We are also committed to postgraduate education and share as a major objective the integration of students into the most important aspects of our investigative work. 

MGDB research is at the cutting edge of many emerging fields, including developmental and reproductive biology, stem cell biology, proteomics, computational biology and geonomics. Our work has direct relevance to acute injury, congenital disorders, cancer, diabetes, muscular dystrophy...
