Suppressive Characteristics of Umbilical Cord Blood–derived Regulatory T Cells After Ex Vivo Expansion on Autologous and Allogeneic T Effectors and Various Lymphoblastic Cells

The third-party umbilical cord blood (UCB)-derived regulatory T cells (Treg) are an alternative to donor-derived Treg as cellular therapy of graft-versus-host disease following hematopoietic stem cell transplantation. However, their suppressive characteristics against autologous and allogeneic T eff
