    Abstract ( 51 )   PDF (4970KB) ( 49 )  
    Objective: Insulin-like growth factor binding protein-2 (IGFBP-2), a member of a highly conserved family of six insulin-like growth factor binding proteins (IGFBPs), can regulate several cellular processes through IGF-dependent or IGF-independent pathway. Recent studies have provided solid evidence for the importance to delineate that olfactory ensheathing cells (OEC)-conditioned medium (OCM) can not only facilitate the differentiation of neural stem cell line (C17.2) into neurons, but also prom...
    Direct interaction of receptor tyrosine kinases, EphA4 and PDGFRβ, plays an important role in the proliferation of neural stem cells
    Qingfa Chen, Takahiro Sawada, Kazushige Sakaguchi, Fabin Han
    2017, 5(1):  133-141.  doi:10.2147/JN.S139820
    Abstract ( 94 )   PDF (653KB) ( 50 )  
    Receptor tyrosine kinases mediate the extracellular signals and transmit them into the cytoplasm by activating intracellular proteins through tyrosine phosphorylation. Both Ephs and platelet-derived growth factor (PDGF) receptors (PDGFRs) have been implicated in neurogenesis, but the functional interaction between these two pathways is poorly understood. Here, we demonstrated that EphA4 directly interacts with PDGFRβ and mutually activates each other when expressed in HEK293T cells. H9-d...
