The world's first clinical trial in which babies receive stem cell treatment while still in the womb will begin in January.
The goal of the fetal stem cell treatment is to reduce symptoms of incurable brittle bone disease, which affects about one in every 25,000 babies. The stem cells will come from aborted fetuses, BBC News reported.
Fifteen babies with brittle bone disease will receive stem cell infusions in the womb and again after birth, while 15 other babies with the disease will only receive stem cells after birth.
The researchers will compare the number of bone fractures that occur in the two groups, BBC News reported.
The study will be led by the Karolinska Institute in Sweden.
