Spring 2025 was a fruitful period in the world of science – several international conferences took place where researchers from around the globe shared their latest discoveries and discussed future directions. Among the active participants were scientists from the Tallinn University of Technology reproductive biology research group, who actively participated by presenting their latest scientific findings and thus made a valuable contribution to the advancement of fertility research.
Associate Professor Agne Velthut-Meikas from TalTech’s Department of Chemistry and Biotechnology, and head of the reproductive biology research group, participated in the first international European Molecular Biology Organization (EMBO) workshop “Ovarian Biology: 1st European Ovary Workshop,” held from February 16–20 in Lagos, Portugal. Agne gave both an oral and a poster presentation, showcasing the research group’s most recent findings. The workshop brought together leading researchers and clinicians from around the world to explore solutions to fertility challenges, addressing key topics such as oocyte development, ovarian aging and dysfunction, and fertility preservation.
“It was a great honor to be part of the creation of a new conference and to meet top researchers from around the world who study this fascinating organ from different angles and across various species. The organizers did an outstanding job. The conference is already set to return in two years, likely on an even larger scale.” Agne said happily.
At the end of April, Velthut-Meikas also presented at the international conference “FEBS3+ Baltics: Biochemistry at the Fore Line”, which took place from April 23–25 at Vilnius University. The event gathered experts in biochemistry and molecular biology from the Baltic states, Finland, and beyond. Agne presented her research group’s latest findings on the role of the ovarian microenvironment in female fertility, making a significant contribution to the diverse program from the perspective of reproductive biology.
From April 23–27, over 1,500 scientists gathered in Vienna to attend the 14th Annual Meeting of the International Society for Extracellular Vesicles (ISEV2025). The conference focused on extracellular vesicles – nanoscale, membrane-bound particles secreted by cells that play a key role in intercellular communication. In recent years, these particles have gained increasing attention for their potential in early disease diagnostics and the development of novel therapeutic strategies.
TalTech doctoral student Inge Varik and master’s student Katariina Johanna Saretok presented posters at ISEV2025, focusing on subpopulations of extracellular vesicles found in human ovarian follicles and their potential biological functions, offering new insights into how these particles may influence the function of follicular cells.
“The atmosphere at the conference was truly inspiring – full of young researchers, vibrant discussions, and cutting-edge science,” said Katariina. “ISEV2025 offered new connections, ideas, and of course, Vienna in its spring beauty left an unforgettable impression.”
Doctoral student Inge also appreciated the opportunity to showcase her research on the international stage: “ISEV2025 was a great opportunity to receive feedback from top scientists and to see how our work aligns with broader developments in the field of extracellular vesicles.” Inge added that, in addition to new knowledge, the conference also provided valuable ideas for future experiments.
