Routine addition of human insulin-like growth factor-I ligand could benefit clinical in-vitro fertilization culture
1 Nov 1998
Abstract excerpt
Animal studies suggest that the insulin-like growth factors play an important role in preimplantation embryo development. Human preimplantation embryos express mRNA for insulin-like growth factor-I receptor (IGF-IR) but the ligand, insulin-like growth factor-I (IGF-I), is not expressed by the embryo until after implantation. We tested the hypothesis that IGF-I produced by the female reproductive tract may bind to...
