Jim Petitte

Professor — Avian Reproductive Physiology and Biotechnology


Scott Hall 362


Area(s) of Expertise

Dr. Petitte works on new technologies for the genetic improvement of poultry and the application of avian stem cells to agriculture and human health.

Research interests include

  • avian stem cells,
  • application of transgenic technology to poultry,
  • an avian model of ovarian cancer and
  • in vitro cell model development.

Current research emphasizes developing a novel gene transfer method for chickens and applying avian biotechnology to biomedicine and agriculture. Recent work on the production of germline chimeras suggests that the use of cells from the early blastoderm as well as isolated primordial germ cells could be used to insert DNA into the avian germline. The culture of avian embryonic stem cells and primordial germ cells is now under investigation using several approaches. In addition, investigations on the origin of primordial germ cells in the developing embryo offer additional clues to the development of transgenic poultry.
