Successful treatment with placenta-derived decidual stromal cells in a pediatric patient with life-threatening acute gastrointestinal graft-versus-host disease.

Severe aGvHD is a life-threatening complication after allogeneic HSCT. The GI tract is considered to play a key role in aGvHD, where the disease process can start and is one of the major target organs. Here, we present a case of a one-year-old child with a life-threatening GI-aGvHD stage IV, post-HSCT, resistant to steroids and MMF for 4 weeks. He was successfully treated with placenta-derived DSC.
