摘要
Applications in transfusion medicine requiring platelets, and hematopoietic stem-cell transplantations require either platelets or enhancement of in vivo platelet biogenesis. Gene therapy applications of hematopoietic stem and progenitor cells (HSPCs) require effective and specific modification of HSPCs by DNA, RNA or other biological molecules. Here we disclose methods for the generation, and modification of megakaryocytic microparticles (MkMPs) or microvesicles, that can be used in the aforementioned transfusion and transplantation medicine applications and in gene therapy applications involving hematopoietic stem cells. The biological effects of modified or unmodified MkMPs have never been previously disclosed and thus, this invention claims all biological applications of MkMPs in in vivo therapeutic applications or ex vivo applications to produce various cells and cell parts, modify various target cells or deliver molecules including drugs to HSPCs and related cells.
