    According to knew scientific studies, stem cells can now be recreated. Geneticists have discovered a way of retracing regular germ and body cells back to their stem cell state.

    This is nothing new. Induced pluripotent cells are actually made by taking somatic or germ line cells and transfecting them with stem-cell associated genes using vectors (e.g retroviruses). In other words… highly differentiated cells can be genetically manipulated to be (epigenetically) reprogrammed into stem cells. This allows them to once again differentiate into a number of different specialised cell types if made to do so. This was first achieved in 2006 for rat cells and in 2007 for human cells.

    There was question whether these cells acted identically to natural embryonic stem cells. Of concern is the increased risk of oncogene expression mainly attributed to the use of viral vectors during the early stages of the procedure.
