Developmental Outcome and Related Abnormalities in Goats: Comparison Between Somatic Cell Nuclear Transfer- and In Vivo-Derived Concepti During Pregnancy Through Term.

Cloning by somatic cell nuclear transfer (SCNT) is characterized by low efficiency and the occurrence of developmental abnormalities, which are rather poorly studied phenomena in goats. This study aimed at comparing overall SCNT efficiency in goats by using in vitro-matured (IVM) or in vivo-matured oocytes and fibroblast donor cells (mock transfected, transgenic, or wild type), also characterizing symptoms of the Abnormal Offspring Syndrome (AOS) in development, comparing results with pregnancies produced by artificial insemination (AI) and in vivo-derived (IVD) embryos. The SCNT group had lower pregnancy rate (18.

Transient Expression of Functional Glucocerebrosidase for Treatment of Gaucher's Disease in the Goat Mammary Gland.

Gaucher disease (GD) is an orphan disease characterized by the lack or incapacity of glucocerebrosidase (hGCase) to properly process glucosylceramide, resulting in its accumulation in vital structures of the human body. Enzyme replacement therapy supplies hGCase to GD patients with a high-cost recombinant enzyme produced in vitro in mammalian or plant cell culture. In this study, we produced hGCase through the direct injection of recombinant adenovirus in the mammary gland of a non-transgenic goat.
