3D mapping of proteins inside cells
Architects often wander through their buildings, examining details up close – gaining a different perspective to a flat drawing or table-top model. Here cell biologists use virtual reality to step inside a cell – strolling past structures they might normally only see twinkling under a microscope, reaching out every now and then to label them in different colours. Looking a little like a child’s climbing frame, this is a reconstruction of a network of intermediate filaments – rigid molecules of keratin that prop up the cell like girders in a skyscraper. The scientist’s models – based on microscopy scans – also give them a sort of virtual skeleton on which to hang future mechanobiological details. Next maybe: the neighbouring network of stretchy actin molecules that uproot this tiny architecture so cells can wander through their environment during development or diseases like cancer.
