WebNov 14, 2007 · Experts have for the first time created cloned embryos from an adult monkey - a technical breakthrough that could bring efficient human cloning a step closer. A team in the US created dozens of cloned embryos from a 10-year-old male macaque, the journal Nature reports. This could make it easier to clone human embryos for use in research. WebTwo methods are used to extract ES cells: the inner cell mass, which consists of the cells that will form the embryo, must be removed to extract the ES cells. Removing this mass often results in the death of this part of the embryo, but it is vital for stem cell research. To obtain a high yield of quality ES cells, embryos must be genetically identical.
