Development of Intergeneric Canine Embryo Using Bovine and Porcine Oocyte as Cytoplasm Recipient

Abstract

This study wa conducted to increase the efficiency of canine embryo production by intergeneric somatic cell nuclear transfer (SCNT) technology. The effect of oocyte recipient for development of intergeneric canine somatic cell cloning embryos were examined. Bovine and porcine cumulus oocyte complexes (COCs) were collected from slaughterhouse ovaries and matured in TCM-199 medium depend on species. Adult dog fibroblasts collected from 3.5 years old Afghandhound dog, and cell between passage 1 and passage 10 used for intergeneric somatic cell cloning using bovine and porcin oocytes as oocyte cytolplasm donor. The result showed that oocytes from bovine and porcine can de-differentiated canine nucleus and no different between bovine and porcine oocyte in fusion and embryo development in vitro. Canine intergeneric cloned embryos developed to morula stages in vitro.
