Triennial Reproduction Symposium Session II: Cell to Cell Interactions

Triennial Reproduction Symposium Session II: Cell to Cell Interactions

By Anne Zinn

On the afternoon of Thursday, July 23, 2020, conference attendees gathered online for the Triennial  Reproduction Symposium II as part of the last day of the ASAS-CSAS-WSASAS Virtual Annual Meeting. The symposium began with the presentation of the second L.E. Casida Award for Excellence in Graduate Education, awarded to Dr. George Seidel of Colorado State University. The first award had been given to Dr. Robert Wettemann of Oklahoma State University during the morning session. After accepting the award. Dr. Seidel discussed his personal philosophy around working with and educating graduate students, emphasizing the idea that students are true colleagues and bring fresh, unique perspectives to the work. Dr. Seidel shared that he feels truly privileged to be a part of graduate education and looks forward to continuing to be a mentor for others. 

After Dr. Seidel’s talk, the session shifted towards the scientific talks for the afternoon, focusing on cell to cell interactions. To begin, Dr. Felipe Percin (University of Sao Paula at Pirassununga) presented on germ and somatic cell interactions during oocyte development and maturation, the lipid metabolism in the cumulus-oocyte complex and lipid accumulation mediated by transzonal projections and fatty acid binding proteins in oocytes undergoing in vitro maturation. Next, Dr. Mario Binella of the University of Florida, Gainesville, discussed the dynamic blastocyst-endometrium interface in cattle. To conclude the session, Dr. Gregory A. Johnson of Texas A&M University presented the results of a recent study that explored using steroids to regulate SLC2A1 and SLC2A3 to deliver glucose into trophectoderm for metabolism via glycolysis in pigs. Results suggest that glucose and fructose transporters are precisely regulated in a spatial-temporal pattern along the uterine-placental interface of pigs to maximize hexose sugar transport to the pig conceptus/placenta.
