Embryonic and adult zebrafish are able to regenerate their hearts after injury. Using specific transgenic lines labelling immune cells and cardiomyocytes, we can use the translucent embryonic zebrafish to provide unparalleled in vivo 4D imaging of immune cell-cardiomyocyte interactions in the beating heart for up to 48 hours. Our group is characterising and manipulating these inflammatory cell events, seeking therapeutic approaches to human heart repair following injury. Image Image Research Methods and Objectives Objective To understand and manipulate immune cell dynamics in the beating embryonic zebrafish heart following injury. Research Methods Laser injury of the embryonic zebrafish ventricle. Single plane illumination microscopy (SPIM) combined with optical gating technology to investigate immune cell responses in our injury model.
