  • Medicine researchers found that retinoic acid (RA), a derivative of vitamin A, regulates the SHF tissue formation and the septation, or division, of the outflow tract into the ascending aorta and the pulmonary artery.


  • Problems in SHF development can also compromise the septation process resulting in a single outflow vessel - a condition known as persistent truncus arteriosus.


  • My laboratory utilizes modern genetic and cell biological techniques to elucidate developmental and molecular mechanisms of aortic arch artery patterning and cardiac outflow tract elongation and septation.
