ALICe

State-of-the-art advanced lightsheet imaging center

Lightsheet microscopes can reveal the 3D anatomy of entire small organs. They image brain tissue down to individual neurons and offer unprecedented maps of nervous system structure and function.

ALICe, the Advanced Lightsheet Imaging Center, integrates a series of innovative fluorescence microscopy tools in a single pipeline to image whole organs with custom-built microscopes at high spatial and temporal resolution. 

The multidisciplinary ALICe team unites expertise from physics, cell biology, neuroscience and engineering, and joins forces with research teams around the world to image and draw insights into the central and peripheral nervous systems, innervation of organs including the brain and heart as well as human brain samples. Another focus area is brain and spinal cord organization for researchers working to restore movement after paralysis or to investigate neuronal networks involved in cognition, pleasure and drug addiction.

Unlike traditional microscopy in which specimens are cut in slices with a blade before being viewed on a slide under a microscope, lightsheet microscopes optically slice samples with a sheet of light. This optical sectioning captures slivers of image without damaging the sample. The images are then combined to reconstruct a detailed three-dimensional image of a whole organ or specimen.


The ALICe pipeline

ALICe’s capabilities cover the entire pipeline, from sample preparation to image capture and post-processing.  A variety of samples can be imaged from organoids to whole organs, labelled with genetically encoded fluorescent proteins or immuno-labeled with fluorescent antibodies.

Expansion microscopy: Visualizing the intricacies of the brain

female scientist looks down microscope
Expansion microscopy deepens our understanding of disease mechanisms to accelerate development of therapies for neurological and psychiatric disorders, like Parkinson’s and Alzheimer’s diseases. Chemical anchors in expanding gel attach to biomolecules, physically expanding the brain sample and allowing as much information as possible to be extracted from the tissue.

"Recent advances in microscopy have propelled the neurosciences into the era of connectomics, now allowing us to study single neurons with their synaptic connections in the whole brain."

Prof. Daniel Huber, Unige
"The work at ALICe allowed us to reveal the distribution and anatomy of sensory receptors with unprecedented resolution and specificity. I was stunned by the quality of the images."
Marianne Web
