How can molecular alterations affect the healthy state of a human being? It is essential to understand this in order to develop new diagnostics and treatments. Yet answering this question requires an all embracing picture – from molecules to cells to organs to organisms. Current bioimaging tools can only reveal the important aspects on one single level. In Cyttron II, fourteen academic and industrial partners collaborate to overcome this problem. We develop tools and integrate the quantitative data of complementary bioimaging technologies to understand the whole picture. In this way we contribute to new powerful diagnostic tools.
