Objective: Insulin-like growth factor-II (IGF-II), a critical regulator of placental development, enhances proliferation and survival of human cytotrophoblasts by signalling through the IGF-1 receptor (IGF-1R). Excess IGF-II binds to IGF-2R, which mediates its transport to the lysosomes for degradation. Although considered to act solely as an IGF-II clearance receptor, IGF-2R has been implicated in mediating IGF-II-stimulated migration and invasion in trophoblast. We therefore...
