Better transplants

A new study suggests that the engraftment process following a bone marrow transplantation could be improved by enriching the graft with stem cells that express a ligand for e-selectin, a molecule expressed on bone marrow microvascular cells. The engraftment process depends on effective seeding of the recipient's bone marrow with haematopoietic progenitor cells ( The Lancet , Vol 357, No 9272).
