摘要
JAK-STAT, PI3K-AKT and MAPK signaling pathways are involved in platelet production process. Although wnt signaling has been reported in the biogenesis of platelets, but its role in megakaryocyte development is not well studied. We used an inducible canonical wnt signaling system that utilizes LiCl (GSK-3 beta inhibitor). LiCl could activate wnt signaling pathway along with maturation of megakaryocytes. Mitochondrial staining showed an increase in mitochondrial mass upon induction with LiCl. Also, mitochondria) markers PGC-1 alpha and TFAM were up regulated with increase in mitochondrial DNA content. LiCl leads to increase in the ROS production, suggesting significance of mitochondria in megakaryocyte development. (C) 2016 Elsevier GmbH. All rights reserved.
