Cloning from adult somatic cells has been successful in at least ten species. Although generating viable cloned mammals from adult cells is technically feasible, prenatal and perinatal mortality is high and live cloned offspring have had health problems. This chapter summarizes the health consequences of cloning in mice and discusses possible mechanisms through which these conditions may arise. These studies have further significance as other assisted reproductive techniques (ART) also involve some of the same procedures used in cloning, and there are some reports that offspring generated by ART display aberrant phenotypes as well. At the moment, the long-term consequences of mammalian cloning remain poorly characterized. Data available thus far suggest that we should use this technology with great caution until numerous questions are addressed and answered.

Nucleolar Remodeling in Nuclear Transfer Embryos

Jozef Laurincik and Poul Maddox-Hyttel

Transcription of the ribosomal RNA (rRNA) genes occurs in the nucleolus and results in ribosome biogenesis. The rRNA gene activation and the associated nucleolus forma- tion may be used as a mark...

Somatic Cell Nuclear Transfer (SCNT) in Mammals: The Cytoplast and Its Reprogramming Activities

Josef Fulka, Jr. and Helena Fulka

It is now more than nine years since Dolly, the world’s first somatic cell cloned mammal was born, and the success of somatic cell nuclear transfer (SCNT) is still disappointingly low. Only abou...

Mitochondrial DNA Inheritance after SCNT

Stefan Hiendleder

Mitochondrial biogenesis and function is under dual genetic control and requires extensive interaction between biparentally inherited nuclear genes and maternally inherited mitochondrial genes. ...

Activation of Fertilized and Nuclear Transfer Eggs

Christopher Malcuit and Rafael A. Fissore

In all animal species, initiation of embryonic development occurs shortly after the joining together of the gametes from each of the sexes. The first of these steps, referred to as “egg activati...
