Researchers report what they say is the first whole-body single-cell atlas of an adult vertebrate, using the tiny transparent fish Danionella cerebrum. The work focuses on mapping cells across the body, including tissue types that are difficult to access in other animals.
The fish is notable for neuroscience research: its brain can be viewed through the top of its head, and it has attracted increasing attention after being adopted for neuroscience studies in 2018 and formally described in 2021. Across outlets, the emphasis centers on the novelty of the atlas—covering the whole adult organism—while Phys.org highlights the species’ transparency and history in neuroscience research. Science Magazine presents the study through its publication listing, indicating its placement in a specific issue, with fewer additional descriptive details.
