These are the cellular components of a zebrafish pectoral fin. Green indicates the endoskeleton; red staining shows the epithelial cells; blue marks the nucleus of each cell. Unlike humans, zebrafish can fully regrow limbs (fins) that have been damaged or lost. Understanding how fin development and regeneration happen in the zebrafish may guide regenerative approaches in humans. PhD student Agnik Dasgupta captured the image using a spinning disk confocal microscope in the laboratory of Jeffrey Amack, PhD, in Upstate‘s department of cell and developmental biology.
