Compositional analysis of dairy products derived from clones and cloned transgenic cattle.

Identification of transgenic cloned dairy goats harboring human lactoferrin and methylation status of the imprinted gene IGF2R in their lungs.

Dairy goat is a good model for production of transgenic proteins in milk using somatic cell nuclear transfer (SCNT). However, animals produced from SCNT are often associated with lung deficiencies. We recently produced six transgenic cloned dairy goats harboring the human lactoferrin gene, including three live transgenic clones and three deceased transgenic clones that died from respiratory fai...

Developmental Competence and Pluripotency Gene Expression of Cattle Cloned Embryos Derived from Donor Cells Treated with 5-aza-2'-deoxycytidine

Meat and milk from cloned bovines meet industry standards

Cindy Tian et al. report that meat and milk from cloned bulls and cows, respectively, appear to meet regulatory standards. The researchers cloned a Japanese Black beef bull and Holstein dairy cow, using somatic cell nuclear transfer, and compared the meat and milk from two beef clones and four dairy clones to that of geneticand breed-matched control animals bred through conventional reproductio...

Cloned cattle controversy

The US Food and Drug Agency could be ruling as soon as next month on draft guidelines for the sale of barnyard clones of cattle and their products: milk, meat and offspring. The regulators are likely to bow to pressure from farmers and the agro-cloning lobby to drop the voluntary moratorium on the sale of genetic material from clones. The new guidelines are widely expected to be liberal, openin...

Comprehensive Assessment of Milk Composition in Transgenic Cloned Cattle

The development of transgenic cloned animals offers new opportunities for agriculture, biomedicine and environmental science. Expressing recombinant proteins in dairy animals to alter their milk composition is considered beneficial for human health. However, relatively little is known about the expression profile of the proteins in milk derived from transgenic cloned animals. In this study, we ...
