Cloning of mammals by nuclear transfer (NT) results in gestational or neonatal failure with at
most a few percent of manipulated embryos resulting in live births. Many of those that …

A commercially viable cattle embryo transfer (ET) industry was established in North America
during the early 1970s, approximately 80 years after the first successful embryo transfer was …

The production of cloned animals is, at present, an inefficient process. This study focused on
the fetal losses that occur between Days 30–90 of gestation. Fetal and placental …

14 develop abnormally is currently unjustified on scientific grounds and should not be used
by policymakers or other groups as an argument to ban all human cloning research. In our …

Over a period of approximately thirty years, commercial bovine embryo transfer has become
a large international business. The technology is well established, and more than 500,000 …

Cloning of buffalos (Bubalus bubalis) through nuclear transfer is a potential alternative
approach in genetic improvement of buffalos. However, to our knowledge, cloned offspring …

Zinc-finger nickases (ZFNickases) are a type of programmable nuclease that can be
engineered from zinc-finger nucleases to induce site-specific single-strand breaks or nicks …

In this study, we demonstrate the use of somatic cell nuclear transfer to produce the first
cloned camelid, a dromedary camel (Camelus dromedarius) belonging to the family …

In ruminants, the greatest period of embryonic loss coincides with the period of elongation
when the embryonic disc is formed and gastrulation occurs prior to implantation. The impact …

Cloning by nuclear transfer (NT) has been riddled with difficulties: most clones die before
birth and survivors frequently display growth abnormalities. The cross‐species similarity in …
