Scientists have determined that chronic wounds might have trouble healing because of the actions of a tiny piece of a molecular structure in cells known as RNA. The researchers discovered in a new animal study that this RNA segment in wounds with limited blood flow lowers the production of a protein that is needed to encourage skin cells to grow and close over the sore.
