By: Varsha Prasad, Genetics ’15 A study to employ a new method of generating human embryonic stem cells without destroying any human embryos is currently being conducted by an international research team led by Karl Tryggvason, Professor Medical Chemistry at Karolinska Institutet and a Professor at Duke-NUS Graduate Medical School in Singapore. The researchers developed a method in which embryonic stem cells can be obtained from a single cell of an eight-cell embryo, which can then be refrozen and placed in the woman’s uterus.  This prevents the need to destroy human embryos in the process.  The idea is that the embryo can survive a single cell removal.
