 Notable achievements announced at WFIRM have been the first [[lab-grown organ]], a [[urinary bladder]], the [[artificial urinary bladder]] to be implanted into a human, as well as [[stem cells]] harvested from the [[amniotic fluid]] of pregnant women.These stems cells are [[pluripotent]], meaning that they can be manipulated to differentiate into various types of mature cells that make up nerve, muscle, bone, and other tissues while avoiding the problems of tumor formation and ethical concerns that are associated with embryonic [[stem cells]].In 2019, the U.S. federal [[United States Department of Health and Human Services|Department of Health and Human Services]] (HHS) supported WFIRM technology that can allow physicians to better understand damage to the body caused by inhaling [[Chlorine|chlorine gas]].
