Endorphin Plays Traffic Cop to Organs

Studies with frogs have demonstrated to researchers at the University of Hohenheim a previously unknown fact: that two chemical messengers are responsible for cell communication in the embryo. The heart, liver, and spleen only move into their correct positions when these two chemical messengers cooperate and trigger a complex chain reaction. Serotonin, known as endorphin or "happy hormone," and wnt are the two substances that are responsible for the asymmetrical right-left development in embryos. They ensure that all organs end up in their proper locations. Both chemical messengers are also important to the bodies of adults. If their interplay is disrupted, cells that should not divide may begin to do so, potentially leading to cancer.
