Tim Mitchison. Reaction-diffusion gradients determine positional information within cells. Gradients of signaling molecules have long been known in developmental biology and paracrine physiology. But gradients within cells that are used as a spatial organization system is a new concept.

I also think that finding that a combination of four transcription factors can induce a pluripotent state was phenomenal and has stimulated much research in the field of stem cells1. Last but not least, the involvement of non-coding RNAs in various cellular and nuclear processes is absolutely fascinating. Mechanisms thereby
which long non-coding RNAs regulate gene expression await exciting discoveries flight.

It was notable that transient overexpression of only four transcription factors, OCT4, SOX2, MYC, and Krüppel-like factor 4 (KLF4) — all naturally expressed by ESCs—could achieve this dramatic dedifferentiation of fibroblasts. This finding enabled researchers to derive patient-tailored iPS cells to study the host biology and various human diseases – a first but important step for the future development of new drugs and treatments in medicine.
