Show abstract
This Protocol Extension describes adapting an existing cryoinjury protocol to study heart regeneration in zebrafish1. We recently characterized a novel hepatic cryoinjury model that induces localized necrosis, inflammation, and fibrosis, which resolves as the liver regenerates. Here, we present a detailed description of the hepatic cryoinjury procedure. One of the key advantages of this model is that it allows direct comparison of healthy and injured liver parenchyma within individual animals. Our hepatic cryoinjury model provides a rapid and reproducible platform to investigate the molecular and cellular mechanisms underlying fibrosis and liver regeneration. This Protocol Extension aims to extend the reach of the cryoinjury approach for deployment in studying liver regeneration.
