| Research Abstract |
Megakaryocytes (MKs) differentiate from hematopoietic stem cells under the control of a lineage-specific cytokine, thrombopoietin (TPO). Final stage of the maturation is characterized by platelet release from the ends of long thin cytoplasmic processes called proplatelet. However, the mechanism for regulating proplatelet formation and platelet activation produced from MKs have not been completely understood. In this study, proplatelet formation and platelet function including CD62P and PS exposure were different between wild-type (WT) and CD226 knockout (KO) or calpastatin KO or p38a +/- MKs and platelets. These results suggest that CD226, calpain-calpastatin and p38 MAPK are involved in proplatelet formation and platelet function.
