The present disclosure provides methods of hematopoietic stem cell transplantation (HSCT). In particular, the present disclosure provides a method of HSCT using a combination of an in-vivo T-cell depletion method, with an ex-vivo method of ?d T cell expansion and aß T cell depletion. The in-vivo T-cell depletion method depletes (in-vivo) the alloreactive T cells that would otherwise increase the risk of GvHD.
