Man-made cilia have shown that the real structures create complex flows of fluid that may contribute to normal development and tissue differentiation in early embryos, according to researchers at the University of North Carolina at Chapel Hill, reporting their linkurl:findings; in __PNAS__.

linkurl:Richard Superfine,; a biophysicist at UNC, lead a team of researchers hoping to more completely explain how a ciliated area called the embryonic node aids in the formation of separate germ layers and in the development of a right-left axis in the embryo. "In order to understand these biological situations, we would have to make our own model and make precise measurements on what the fluid flows were like," Superfine told __The Scientist__. Superfine added that his group has so far created the model -- made from...
