The Allen Institute for Cell Science has released the Allen Cell Collection: the first publicly available collection of gene edited, fluorescently tagged human induced pluripotent stem cells that target key cellular structures with unprecedented clarity. Distributed through the Coriell Institute for Medical Research, these powerful tools are a crucial first step toward visualizing the dynamic organization of cells to better understand what makes human cells healthy and what goes wrong in disease.
