Mesenchymal stem cells are present in peripheral blood and can engraft after allogeneic hematopoietic stem cell transplantation.

Abstract

These findings indicate that after allogeneic transplantation MSC from the donor can engraft in bone marrow. Moreover, since the stem cells were obtained from peripheral blood, it can be concluded that MSC circulate among mobilized peripheral blood stem cells and can engraft in bone marrow after allogeneic transplantation.
