A new "app" for finding and mapping chromosomal loci using multicolored versions of CRISPR/Cas9, one of the hottest tools in biomedical research today, has been developed by scientists at the University of Massachusetts Medical School. This labeling system, details of which were published in PNAS and first presented at the American Society for Cell Biology/International Federation for Cell Biology annual meeting in Philadelphia in December, could be a key to understanding the spatial and temporal regulation of gene expression by allowing researchers to measure the precise linear distance between two known points on different chromosomes or two locations on the same chromosome in live human cells.
