Credit: Aleksandra Krolik/EMBL Researchers in the Friedrich group have contributed to create an atlas that links subcellular structures to gene expression in each cell of the sea worm Platynereis dumerilii , a key model organism for the study of development and evolution. The atlas will help researchers to shed light onto molecular and cellular mechanisms at play in our very ancient ancestors. A distant cousin of the leech, Platynereis dumerilii is a nondescript sea worm. But the humble creature has become an important model organism to understand development and evolution. Now, researchers in the group of Rainer Friedrich and their collaborators at EMBL have developed an interactive atlas that allows scientists to explore the structure and gene expression of each cell found in a Platynereis worm. The study was published last month in Cell .
