As an organism grows, the feel of it changes too. In the initial stages, an embryo takes on an almost fluid-like state that allows its cells to divide and expand. As it matures, its tissues and organs firm up into their final form. In certain species, this physical state of an organism can be an indicator of its developmental stage, and even the general state of its health.
Now, researchers at MIT have found that the way in which a tissue’s cells are arranged can serve as a fingerprint for the tissue’s “phase.” They have developed a method to decode images of cells in a tissue to quickly determine whether that tissue is more like a solid, liquid, or even a gas. Their findings are reported this week in the Proceedings of the National Academy of Sciences.
