- MIT researchers developed a new imaging method called expansion revealing that can visualize up to five different molecule types at a time within a cell¹.
- The method is based on expansion microscopy, which involves embedding cells in a polymer gel and expanding them to make them easier to image¹.
- Expansion revealing allows scientists to measure each signal from random, distinct locations throughout a cell, overcoming the limitation of conventional microscopy that can only distinguish between a few fluorescent colors¹.
- The researchers used expansion revealing to identify two populations of neurons that respond to calcium signals in different ways, which may influence how they encode long-term memories¹.
- Expansion revealing could enable studies of complex signaling networks that control most cell functions, and potentially lead to new insights into diseases such as cancer and Alzheimer’s¹.
