Characterization of induced pluripotent stem cell-derived megakaryocyte lysates for potential regenerative applications.


ABSTRACT: Recently, platelet-derived growth factors present in lysates became an extreme interest in the field of regenerative medicine such as in wound healing and as substitutes to foetal bovine serum in xeno-free cell culture systems. However, the generation of such platelet lysates completely depends on the availability of platelet donors. In this study, the possibility to use in vitro-generated megakaryocytes derived from induced pluripotent stem cells (iPSCs) as a cell source for typical platelet growth factors was investigated. Therefore, the presence and levels of those factors were characterized in in vitro-produced megakaryocytes. In comparison with platelets, in vitro-generated megakaryocytes showed a multifold increased content in transcript and protein levels of typical platelet growth factors including platelet-derived growth factors (PDGFs), transforming growth factor (TGF)-1?, vascular endothelial cell factor (VEGF)-A, epidermal growth factor (EGF), insulin-like growth factor (IGF)-1 and tissue factor (TF). Hence, iPSC-derived megakaryocytes may serve as an efficient cell source for a donor-independent generation of growth factor-rich lysates with a broad application potential in innovative cell culture systems and regenerative therapies.
