Challenges in the clinical application of induced pluripotent stem cells.
The advent of human induced pluripotent stem cells has been heralded as a major breakthrough in the study of pluripotent stem cells, for these cells have yielded fundamental insights into the reprogrammability of somatic cell fates, but also because of their seemingly great promise in applications, including potential uses in cell therapy. Several recent reports in the scientific literature and mass media, however, have challenged this concept for reasons of biological function and business feasibility, presenting an important opportunity to re-examine the prospects for human induced pluripotent stem cells in medicine. In this commentary, I will outline a number of hurdles that will need to be cleared if these cells are to fulfil their clinical promise, and suggest avenues that might facilitate these important endeavours.
