Gene discovery reveals potential for growing new heart arteries

Most people have right-dominant hearts—which to a doctor or a researcher means they have an artery that extends from the right side of their hearts to supply oxygenated blood to the back side. For some people, this artery, called the posterior descending artery, comes from the left side or from both directions. A study has found that the gene CXCL12 is connected to this artery's formation and that its directional pattern is set very early in human development.
