Genetics and Development
| Andy Wessels, Ph.D. - Division Director|
The Division of Genetics and Development offers training and research in the field of genetics and developmental biology, which utilizes a variety of animal models to assess the gene functions in embryonic development. Modern developmental genetics has become the central organizing field in all traditional disciplines in biology, such as cell biology, molecular biology, anatomy, evolution, and ecology. It has also contributed greatly to more practical fields such as medicine, environmental science and agriculture. The model systems studied by the faculty members include Drosophila (fruit fly) for oogenesis and vascular system development, zebrafish for environmental impact on embryogenesis, Xenopus (frog) for neurogenesis, chick for the formation of cardiovascular system, mice for a variety of organogenesis such as limb and follicle development, hematopoiesis, heart formation and mammary development, and human familial diseases for genetic linkage studies. In addition to transgenic and knockout technology, a variety of cell culture systems, including those for human stem cells, are utilized in the research.

The picture shows a new-born mouse [top] defective in hair follicle development as compared to the normal animal [bottom]. The defect is induced by Hox gene over-expression.
Genetics & Development Course Descriptions
Cellular signaling during Development MCBP-743
This course is designed to build on the Regulation of Gene Expression, Biomembranes, Receptors and Signaling and Systems Biology units of the first year curriculum for Ph.D., and complement ongoing department-specific seminars and journal clubs. Cellular Signaling during Development will provide the students with an in depth look at ongoing research in the field of developmental biology with a strong focus on the signaling networks that control the important developmental processes. Emphasis will also be placed on the pathology of dysregulated signaling mechanisms in diseases. It will allow for a broad scope of understanding of the techniques, theories and practices involved in the delineation of cellular signaling in complex systems. The course will begin, in the first 2 sessions, with an outline of and introduction to topics to be discussed. Review and discussion of papers by the students will follow. For each paper discussed the presenting student will first provide overviews that will serve as background material. Grades will be based on the quality of presentation and participation.
3 credit hours
Course Director: Robin Muise-Helmericks, Co-Director: Rick Visconti
The course is offered in the Spring Semester of alternate years (starting 2005).
