Intestinal Tumorigenesis Initiated by Dedifferentiation and Acquisition of Stem-Cell-like Properties Florian Greten and colleagues explain why enhanced Wnt signaling causes postmitotic (non-stem) cells to dedifferentiate and reacquire stem cell characteristics, enabling the cells to initiate tumorige... Spatially Addressable In Vivo Optogenetics with Multipoint-Emitting Optical Fibers This video describes the implementation of a new optogenetic tool based on a single waveguide that, by a simple optical strategy, can selectively and dynamically illuminate multiple brain regions.
