In living organisms, development is a combination of multiple coordinated processes that interact in time and space over the course of growth. One false note in the delicate symphony can have catastrophic consequences. However, the precise score of this biological music is often a mystery to scientists. One solution is to use advanced microscopy techniques to observe organ growth in real time. The challenge is that such approaches are poorly suited to long-term monitoring. Furthermore, they can stress organs, disrupting development.
