For Part I of this blog, I will highlight a new discovery where scientists have now been able to create cloned stem cells and I will review two ethical debates that were central to earlier discourse surrounding stem cell research: (1) the moral status of human embryos and (2) the potential physical and social harms to women as egg providers.
So finally research cloning (a.k.a. therapeutic cloning) has been achieved! The technique is called somatic cell nuclear transfer (SCNT) and now has been used to derive human embryonic stem cells (hESCs) (Tachibana et al., Cell 2013). Performing SCNT using human oocytes is an astonishing accomplishment and has significant ethical and clinical implications.
