Full-term devel- opment of mice from nuclear transfer of blastomeres was eventually demonstrated in 1987 buy discount valtrex 500mg line hiv infection rates in los angeles. However discount valtrex 1000mg on line antiviral quizlet, the rates were low compared to sheep and cattle, possibly due to differences in the requirements for activation following nuclear transfer. These results emphasize the considerable variation in the success in cloning mammals using blas- tomeres as donor cells. Unlike earlier results using nonmammalian species, serial nuclear transplantation did not offer any substantial improvement in developmen- tal potential. Nonetheless, results from mice, rabbits, and cattle all suggest that reprogramming of cellular fates is dramatically restricted in eight-cell embryos and beyond. The prevailing wisdom was thoroughly shaken by the reports of Dolly—a normal sheep that developed to term following nuclear transplantation of a donor nucleus from a single mammary epithelial cell. Not only was Dolly cloned from somatic cells but it was from adult cells providing a dra- matic confirmation of the earlier work of Gurdon (1970). This was followed by nuclear transplantation of embryonic fibroblasts to clone cattle, sheep, and goats. Cumulus cells from adult animals have also been used as donor cells to clone mice and cattle. The results from animals cloned using somatic cells from mammals substan- tiate much of the work performed in amphibians; however, the data are far from complete (summarized in Table 2. It is clear that a variety of somatic cell types are capable of undergoing nuclear reprogramming following nuclear trans- plantation and yield live offspring. However, efficiency of nuclear reprogram- ming is very dependent on the donor cells. Cumulus cells and fetal fibroblasts have proven to be competent donors in two species, whereas trophectodermal cells were consistently negative in two studies.
