Scientific Sessions


Keynote Address

Saturday 21 July, 5:30–6:30 p.m., Salons E–F, immediately following the Opening Ceremony and Awards Presentations.

Haifan Lin, Ph.D. (Professor, Department of Cell Biology, Director of Stem Cell Program, Yale University, New Haven, Connecticut): Stem Cells, Small RNAs, and Self-Renewal.

Dr. Lin’s research has centered on the identification of genes critical to stem cells of the germ cell line. He has used Drosophila and the mouse for combined genetic, cell biology, and molecular studies to explore the mechanisms underlying stem cell division and self renewal. The piwi genes that he identified in Drosophila define a family of evolutionarily conserved genes that are essential for stem cell division in both animal and plant kingdoms. He has focused more recently on the function of mammalian members of the piwi family genes in germline stem cell divisions in mice and humans and on the evolutionarily conserved mechanisms that regulate stem cell division. A mammalian homolog of piwi has been identified as a master regulator gene of spermiogenesis and that serves as the binding protein for a novel and very large class of small RNAs found only in high numbers spermatids.

President’s Symposium: Gene Networks Critical for Reproduction

Saturday 22 July, 1:00–2:30 p.m., Salons E–F.

Linda C. Giudice, M.D., Ph.D. (Professor and Chair, Department of Obstetrics and Gynecology, University of California San Francisco, San Francisco, California): Molecular Phenotyping of the Cycling Human Endometrium and Hormonally Regulated Genes Important for Implantation.

While Dr. Giudice’s research focuses on the human, the questions asked and the approaches used are relevant to understanding and preventing fetal loss in other mammals. Her laboratory has had a long-standing interest in the role of normal and abnormal endometrial development and its relevance to implantation, miscarriage, fetal growth, and endometriosis in humans. This research includes studies of the roles of the insulin-like growth factor (IGF) system and the Wnt family in human endometrium, the role of the IGF system in human trophoblast invasion and function, and functional genomics of human reproductive tissues. The latter studies include molecular profiling of human placental trophoblasts at different gestational ages and in pregnancy disorders, as well as the human oviduct under different hormonal conditions and disease states.

Michael D. Griswold, Ph.D. (Professor, School of Molecular Biosciences; Dean, College of Sciences, Washington State University, Pullman, Washington): Expression Profiling of the Control of Germ Cell Maturation by Sertoli Cells—from Discovery to Hypothesis.

The research in Dr. Griswold’s laboratory is directed towards understanding mammalian spermatogenesis at the molecular level. These efforts have concentrated on delineating the influence of Sertoli cells on the process of germinal cell differentiation and maturation. Some of his ongoing research is on the characterization of the promoter for the FSH receptor gene that is expressed specifically in Sertoli cells, and the use of spermatogonial transplantation to characterize Sertoli-germ cell interactions in vivo. His major efforts recently have been on the use of microarray analysis to identify patterns of gene expression during male germ cell development and genetic networks that regulate this process. Dr. Griswold’s research has been with laboratory animals, but continues to provide insights into basic mechanisms and processes operating in other mammals.

State-of-the-Art Lecture I

Monday 23 July, 1:00–1:45 p.m., Salons E–F.

Marco Conti, M.D. (Professor, Department of Obstetrics and Gynecology, Stanford University Medical Center, Stanford, California): Signal Transduction and Gamete Function: A 2007 Perspective.

Dr. Conti’s research has concerned identifying the regulatory module of the cAMP second message within the cell that balances cAMP synthesis by cyclases and degradation by phosphodiesterases (PDEs). Dr. Conti has identified and characterized several genes coding for these enzymes, and has used a wide array of approaches ranging from the enzymology of isolated proteins to genetic inactivation of genes in laboratory animals to understand how cyclases and PDEs are regulated and assembled in macromolecular complexes. Current studies seek to define the role of these signaling modules during activation of inflammatory cells, during differentiation of somatic cells in the male and female gonads, and in the differentiation of germ cells.

State-of-the-Art Lecture II

Tuesday 24 July, 1:00–1:45 p.m., Salons E–F. (supported in part by the USDA-CSREES-NRI.)

Mark E. Westhusin, Ph.D. (Professor, Department of Veterinary Physiology and Pharmacology, Texas A&M University, College Station, Texas): Cloning of Food Animals and Endangered Species.

Dr. Westhusin’s research program is focused on the development and application of assisted reproductive technologies in mammals, particularly the use of somatic cell nuclear transplantation for cloning different animal species. His research has involved cattle, sheep, goats, dogs, cats, horses, and several wildlife species. These studies have shown that in spite of successes and regardless of the species, animal cloning remains an inefficient process, with less than 5% of cloned embryos resulting in live offspring following transfer into recipient females.

Historical Perspectives Lectures: Oocyte-Somatic Cell Communication

Wednesday 25 July, 10:00 a.m.–12:00 noon, Salons E–F.

John J. Eppig, Ph.D. (Senior Staff Scientist, The Jackson Laboratory, Bar Harbor, Maine): Oocyte Control of Mouse Cumulus Cell Development and Function.

Dr. Eppig’s research program is focused on the development and function of the mammalian oocyte-granulosa cell complex. He achieved the first complete development of mammalian oocytes in vitro. This included in vitro initiation of primordial follicle development, oocyte growth, and acquisition of competence to undergo maturation, fertilization, and, after transfer of preimplantation embryos to foster mothers, the birth of live young. He originated the concept of an oocyte-granulosa cell regulatory loop in which bi-directional communication between the oocyte and companion granulosa cells is essential for both normal oocyte and follicular development. A major goal of his current research is to define the components of this regulatory loop and their mechanism(s) of action. Finally, he is a participant in the ReproGenomics Program Project to develop mouse mutant models of infertility using ENU mutagenesis.

Kenneth P. McNatty, Ph.D. (Professor, Victoria University of Wellington, Wellington, New Zealand): Journeys from Inheritance Patterns of Ovulation Rate in Sheep to Factors Influencing Oocyte-Somatic Cell Communication in Mammals.

Research in Dr McNatty’s laboratory has focused on identifying the genes responsible for the unusual inheritance patterns of ovulation rate observed in screened prolific sheep lines. From extensive controlled breeding experiments, genetic linkage mapping and physiological studies, Dr McNatty and his team have identified several point mutations in the BMP15 gene and one each in the GDF9 and ALK6 genes in different breeds/lines of animals. Expression of all of these genes within the ovary was localized to oocytes with ALK6 also being localized to cumulus/granulosa cells. Subsequent in vitro and in vivo experiments in rodents and/or ruminants support the hypothesis that the level of oocyte-somatic cell communication, via the growth factors GDF9 and BMP15 and the receptor ALK6, have profound effects on ovarian follicular development and on the number of follicles that ovulate.
