Zebrafish rebuild damaged 'second brain' networks in nine days, offering clues for nerve repair
Researchers at Michigan State University have developed a method to observe the regeneration of gut neurons in zebrafish. This discovery provides insights into how the enteric nervous system repairs itself, which could eventually inform human nerve treatment.
Why it matters
Understanding how zebrafish regenerate nerve tissue could lead to breakthroughs in treating human digestive and neurological disorders.

DOI: 10.1016/j.stemcr.2026.102966 Why can zebrafish regenerate damaged gut nerves while humans largely cannot? Michigan State University researchers have developed a new research tool that allows them to remove gut neurons in zebrafish and watch them regenerate in real time, helping scientists investigate one of regenerative biology's biggest questions. The work is published in the journal Stem Cell Reports .
