How do you image the large and the small at the same time? We developed new 🔬 technology to image centimeter-scale specimens - including whole mouse brains 🧠 - with diffraction-limited resolution and without sectioning. #mesoscale #imaging

ExA-SPIM is a technology based on innovations in (1) tissue processing and (2) large-scale microscopy 🔬. Our team developed new methods for expansion for microscopy (ExM) of large tissue volumes. #teamscience #expansionmicroscopy

By combining ExM with a new SPIM system based on technologies from electronics metrology, ExA-SPIM pushes past the volumetric imaging barrier 🚧 that constrains previous imaging approaches. (inspired by recent plot from @Daetwyler_St, @RetoPaul) #lightsheet #microscopy

Introducing #panExM-t: a protocol where 🧠 tissue is expanded ✨24x✨, pan-stained with NHS ester, and immunolabeled.
Now you can see everything in the brain, even synaptic densities 👇. High potential for #connectomics!

Here's a data set showing synapses, mitochondria, and spine apparatuses
We found synapse morphology can be classified according to their NHS ester pan-staining patterns - similar to PTA staining in EM (Gray) Image

How do brains rewire throughout life?

Our paper out in @Nature today outlines several principles of brain circuit development that we found by mapping the complete wiring of eight brains.
