replacement tissues which prevents rejection by the immune system of a patient is a step closer to the clinic, the researchers created human embryonic stem cells carrying the DNA of specific adults. In theory, these stem cells may form any cell type of the organism and can be used in new treatments for Parkinson's disease, diabetes, multiple sclerosis, heart disease, and spinal injuries spinal. The researchers reported the creation of stem cells using skin cells of a 35-year-old male and a 75-year-old male yesterday Cell Stem Cell . Scientists have built on the work of a team led by Shoukhrat Mitalipov of the Health & Science University in Portland Oregon. The group Mitalipov removed the nucleus containing DNA from human eggs and replaced with cells from the skin of infants and fetuses, a technique called nuclear transfer of somatic cells (SCNT). SCNT has been used to clone Dolly the sheep in 1996. Rather than humans clones, researchers take the early stage embryos resulting from SCNT then derive stem cells (photo above, marked by red fluorescence). Mitalipov The group was the first to get to work SCNT in humans, as they reported in Cell in 2013. But they used donor cells from fetuses and infants. The team of the new study showed that, with minor modifications, the technique works for adults.
