The 68th Annual Meeting of JALAS was held online. Four members made presentations at the poster session. *Poster Session* K. MOCHIDA: Easy and quick (EQ) sperm freezing method for mouse strains. N. OGONUKI: Improvement of microinjection with primary spermatocytes. A. HASEGAWA: Newsuperovulation method for increasing litter size of C57BL/6J mice and its application to i-GONAD. N. WATANABE: An attempt to establish nuclear transfer Embryonic Stem Cells from wild-derived mouse strains.

Ms Naomi WATANABE Title： Establishment of nuclear transfer Embryonic Stem Cells from wild-derived mouse strains

A symposium co-organized by two Innovative Areas, “Ensuring integrity in gametogenesis” and “totipotency program”, was held as a hybrid meeting (on site: Tokyo University of Agriculture).

2020 SRD meeting was held online. A screen shot from Symposium on Totipotency (Co-organized with Grant-in-Aid for Scientific Research on Innovative Areas “Program of totipotency”). Mr. Keiji MOCHIDA won the JRD Outstanding Paper Award (2019). Mochida et al. “Early production of offspring by in vitro fertilization using first-wave spermatozoa from prepubertal male mice.” Dr. Helena Fulka also won the award and the certificate and auxiliary prizes were given to her in Czech. Fulka et al. ” Dissecting the role of the germinal vesicle nuclear envelope and soluble content in the process of somatic cell remodelling and reprogramming.”

Dr. Chen-Cheng Lee (Genomics Research Center, Academia Sinica, Taiwan) learned the technique of mouse nuclear transfer cloning. The first cloned mice in Taiwan will be born soon.
