Abstract/OtherAbstract:
SummarySomatic cell nuclear-transferred (SCNT) oocytes have a high potential for development in vitro, but a large proportion of embryos that are transferred to recipients is aborted before parturition. The precise mechanism for the high abortion rate is unknown, but abnormal placenta formation is frequently observed in SCNT-cloned pregnancies. The present study examined the effects of treating the recipients with cyclosporin A (CsA), an immunoprotectant, on the proportion of fetuses resulting from SCNT-cloned pregnancies. Cloned embryos developed from enucleated oocytes and receiving cumulus cells from F1 (C57BL/6 × DBA, H-2b/d) females were transferred to outbred ICR (in which the H-2 complex was not fixed) recipient females. Each recipient received an intraperitoneal injection of CsA or vehicle. Compared with vehicle, administration of CsA to recipients on day 4.5 of pregnancy significantly increased the proportion of fetuses observed on day 10.5. The proportion of fetuses at day 18.5 of pregnancy in recipients receiving CsA treatment was slightly higher than that in controls. This study is the first to report that CsA administration increases the proportion of fetuses resulting from SCNT-cloned pregnancies.
