Molecular biologists provide exciting insights into the bristles of the marine annelid worm Platynereis dumerilii. Specialized cells, so-called chaetoblasts, control the formation of the bristles. Their mode of operation is astonishingly similar to that of a technical 3D printer.
A new interdisciplinary study led by molecular biologist Florian Raible from the Max Perutz Labs at the University of Vienna provides exciting insights into the bristles of the marine annelid worm Platynereis dumerilii. Specialized cells, so-called chaetoblasts, control the formation of the bristles. Their mode of operation is astonishingly similar to that of a technical 3D printer.
The exact biological background to this: so-called chaetoblasts play a central role in this process. Chaetoblasts are specialized cells with long surface structures, so-called microvilli. These microvilli harbor a specific enzyme that the researches could show to be responsible for the formation of chitin, the material from which the bristles are ultimately made. The researchers' results show a dynamic cell surface characterized by geometrically arranged microvilli.
In addition to the local collaboration with the Vienna University of Technology and imaging specialists from the University of Brno, the cooperation with the Jokitalo laboratory at the University of Helsinki proved to be a great benefit for the researchers at the University of Vienna.

Review: Nature and human nature mingle in the beguiling 'Evil Does Not Exist'The films of Ryusuke Hamaguchi unspool with elegant everyday ease and yet anything can happen. Lives take sudden detours. Seemingly minor characters become primary ones. People are brought together by mysterious connections. There are even, as in the case of his “Asako I & II,” doppelgangers.
