[Clinical study of umbilical cord-derived mesenchymal stem cells for treatment of nineteen patients with steroid-resistant severe acute graft-versus-host disease].

Abstract

Infusion of umbilical cord-derived MSCs expanded in vitro is an effective therapy for patients with steroid-resistant severe aGVHD without negative impact on relapse. Freshly prepared MSCs are superior to frozen and thawed cells in terms of cell viability.
