Cross-section of the Developing Zebrafish Heart
There are a multitude of signals that elegantly orchestrate the proper development of the heart. In this image of a 3-day-old zebrafish heart, the signal that is localized to the developing atrio-ventricular valve and smooth muscle is labeled in green using green fluorescent protein (GFP). This particular signal is important for the formation of the cardiac valves, which will allow blood to pass from the … Continue reading Cross-section of the Developing Zebrafish Heart
