‘Scientists have identified a new shape called the scutoid, a discovery that helps explain how cells arrange themselves in tightly packed three-dimensional structures that serve as protective barriers in the body.
The shape was discovered while a team of researchers was studying epithelial cells, which are the safety shields of the body that make up the cell walls lining our blood vessels and organs. As tissues and organs develop, epithelial cells squish together, twisting and turning into highly efficient and complex three-dimensional structures that help block microbes from entering our skin or organs.
But the shape of these cell structures has long been a mystery to scientists. Some have proposed they were shaped like prisms or cylinders, but a new paper published in Nature shows how scientists used computer modeling and imaging to settle the question once and for all….’
