Immunology letters, 163(1), 84-95 (2014-12-03)
Platelets, like stromal cells, present antigen only via MHC class I, but the immune potential of their progenitors has not been explored in humans. We derived CD34(+)CD117(+)CD41(+)CD151(+) megakaryocyte progenitors (MKp) in vitro from mobilized peripheral blood hematopoietic stem and progenitor
