Although severe combined immune deficiency (SCID) is a very important research model for mice and SCID mice are widely used, there are only few reports describing the SCID pig models. Therefore, additional research in this area is needed. In this study, we describe the generation of Recombination activating gene-1 (Rag-1)-deficient neonatal piglets in Duroc(More)
Hepatitis E virus (HEV) causes not only endemics via a fecal-oral route but also sporadic cases via zoonotic transmission or blood transfusion. HEV-like particles (HEV-LP) produced by using a baculovirus expression system are considered a candidate for mucosal vaccines for HEV infection. In this study, we attempted to produce a chimeric HEV-LP presenting(More)
Blastocyst complementation (BC) systems have enabled in vivo generation of organs from allogeneic pluripotent cells, compensating for an empty germ cell niche in gene knockout (KO) animals. Here, we succeeded in producing chimeric beef cattle (Wagyu) by transferring allogenic germ cells into ovaries using somatic cell nuclear transfer and BC technology. The(More)
