We focus on understanding how mechanical forces shape the zebrafish heart using advanced imaging techniques. By combining our knowledge of biology, physics, microscopy, and computing, we develop tools for optical imaging and image analysis to study how mechanical stimuli influence the way the cardiovascular system develops. A beating heart generates several type of forces, such as pressure for the shear and contractor force.
Although each of these forces has a function in vitro culture systems, it is difficult to separate these parameters in the in vivo heart. By developing our approach, we aim to tackle this challenging task. We have established a novel approach to assess, adapt biological output caused by external force stimulation, and we verified our force spin and constant signal in crosscutting the cardiac cells.
As a result this approach enables us to impetrate other aspects of tissue neurogenesis in the world of mechanical biology. This method enables the study of heart function in zebrafish embryo via targeted mechanical stimulation. Unlike genetic, pharmacological, or optogenetic approaches, pit grafting offers a more direct way to influence heart physiology through mechanical means.
Pit grafting is viable for examining the roles of mechanical forces and calcium influx in cardiac biological processes. It provides means to deepen our understanding of the mechanical transduction pathways involved in heart development and function.
