Ten Years of Induced Pluripotency

It has been a decade since researchers first discovered the recipe for reprogramming ordinary somatic cells into induced pluripotent stem cells, capable of generating all other cell types in the same way as embryonic stem cells. This was a transformative advance, as the ease of the method allowed near any research group to work with pluripotent cells. Making use of induced pluripotency in research and medicine is still very much a work in progress, however: great strides are being made in the production of cells and tissues for drug testing and other tissue engineering for research use, but the goals of generating patient-matched cells and tissues for cell therapies and transplantation are not proceeding as smoothly as was perhaps hoped by some. This popular science article surveys the field: Human cortex grown in a petri dish. Eye diseases treated with retinal cells derived from a patient's own skin cells. New drugs tested on human cells instead of animal models. Research and emerging treatments with stem cells today can be traced to a startling discovery 10 years ago when researchers reported a way to reprogram adult mouse cells and coax them back to their embryonic state - pluripotent stem cells. A year later, they accomplished the feat with human cells. The breakthrough provides a limitless supply of induced pluripotent stem cells (iPSCs) that can then be directed down any developmental path to generate specific types of adult cells, from skin to heart to neuron,...
