At the University of Utah, biologists led by Jamie Gagnon compared zebrafish, which regenerate heart tissue, with medaka, which does not. They found potential reasons for how zebrafish can repair their hearts, primarily related to the immune system. Postdoctoral researcher Clayton Carey, lead author of the study, highlighted the importance of comparing these fish to understand their differences in heart-healing abilities.
