RIKEN Summer School 2023 was held at RIKEN Wako on September 6-7, and four members of our lab gave poster presentations. Ms. WATANABE received the Poster Award Biology Prize. *Poster Presentation* Naomi WATANABE：Preservation of wild-derived mouse strains by nuclear transfer using peripheral blood cells Takaki TATEBE：Analysis of protein degradation systems in SCNT embryos PHAM Quoc Dinh：Establishment and characterization for transgenic cloned mice harboring human erythropoietin gene produced by genome editing and nuclear transfer Syun TOKITA：Differences in the quality of ROSI-derived embryos among experimenters who generated them

Dr. Shogo Matoba was invited to give a lecture at the 166th Annual Meeting of the Japanese Society of Veterinary Science held online from Sep.5 to 8. *Invited lecture* Subcommittee for Veterinary Anatomy Satellite Forum “Studies of Totipotency and its Applications” Title: Totipotency in Eggs and its Application to Somatic Cell Nuclear Transfer Technology

IWATE University students (Faculty of Agriculture, Veterinary Medicine Cooperative) visited our lab.

Ms. Naomi WATANABE of our laboratory participated in the ” IGH summer school on Genome Stability and Organization” organized by the Sasakawa Foundation and co-organized by the Institute of Human Genetics, University of Montpellier (France), and gave a poster presentation and an oral presentation. Title: Preservation of wild-derived mouse strains by nuclear transfer using peripheral blood cells *Comment by Ms. Watanabe* It was a stimulating week for me, as we were a group of young researchers, including French and Japanese doctoral students and post-doctoral fellows. After the school, French students showed us around Montpellier, and we had dinner together. We shared our problems that are unique to students, were surprised […]

The BRC student gathering was held at the initiative of Team Leader Yohei HAYASHI, Ph.D.(iPS Cell Advanced Characterization and Development Team), with the aim of allowing the 15 students and PIs affiliated with the BRC to get to know each other without feeling tense. Dr. Ogura, Ms. Watanabe, Mr. Pham, Mr. Tatebe, and Mr. Tokita participated from our lab.
