Converging Advances in Reproductive Biomedicine and Stem CellTechnology: Reflections from The 25th and 20thRoyan Congresses: A Commentary.

International Congress on Stem Cell Biology and Technology, held in Iran, brought together leading global experts to discuss pioneering advances in stem cell research and reproductive medicine. Key topics included recent progress in somatic and pluripotent stem cells toward clinical applications, developments in regenerative medicine for diverse diseases, innovations in tissue engineering, the integration of artificial intelligence (AI) in biology research, and novel strategies for treating infertility. The congresses fostered collaboration and knowledge exchange across these rapidly evolving fields, highlighting the transformative potential of stem cells in regenerative medicine and their applications in reproductive health. Participation of 33 scientists from the United States, the United Kingdom, Germany, Austria, Italy, Belgium, Turkey, China, Russia, Japan, Sweden, Switzerland, Qatar, and India facilitated a rich exchange of ideas and broadened international perspectives. The insights and outcomes from these congresses are expected to shape ongoing research initiatives and clinical practices worldwide, emphasizing the importance of continued investment in these critical areas of medicine.
