![]() They found not only that the stem cells did have receptors for ANS neurotransmitters, but also the neurotransmitters changed the behavior of the cells - just what they would expect to see for a direct relationship. To characterize the relationship, the researchers focused on stem cells in the intestinal lining, or epithelium, in mice. Instead, you could just figure out what neurotransmitters are controlling proliferation and then get that chemical to those stem cells with targeted drug delivery," says Megan Dailey, assistant professor in the Department of Animal Sciences at U of I and co-author on the paper. "If you wanted to change the regeneration potential of an organ, for example, you wouldn't have to stimulate or suppress the activity of those neurons. A direct relationship could have greater implications for drug interventions to treat medical conditions. Prior to Davis's study, which is published in Physiological Reports, scientists had suspected the ANS was involved in stem cell proliferation, but they didn't know if the relationship was direct or indirect. But changes in cells can also occur when neurotransmitters induce a general state of inflammation or alter blood flow, an indirect route of action for the ANS. When neurotransmitters bind to receptors in the membranes of certain cells, they elicit a direct response within the cell. These neurons release chemicals called neurotransmitters, which can affect target cells directly or indirectly. Its two major networks of nerve fibers run from the brain through the entire body, with neurons reaching into nearly every organ. The ANS controls all of our unconscious functions: breathing, blood flow, digestion, and so forth. doi:10.1016/j.neuron.2012.08."If we could find a way to target and control stem cell proliferation in the body, there could be potential medical benefits, including turning off the proliferation of cancer stem cells or inducing proliferation of somatic stem cells where we want to grow tissue," says Elizabeth Davis, doctoral researcher in the Neuroscience Program at U of I and lead author of a study that demonstrates, for the first time, that stem cell proliferation is directly controlled by the autonomic nervous system (ANS).
