| abstractText | While the targeted disruption of a gene is a powerful tool for investigating the physiological functions of that gene, disruption of a gene essential for embryogenesis leads to embryonic death. Rescue of the defect(s) causing embryonic death should promote survival, thus permitting further evaluation of the roles that the gene plays later in the developmental process. Disruption of the gene for mouse hepatocyte growth factor/scatter factor (HGF/SF) leads to middle-stage embryonic lethality because of a defect in placental development. Here we report that a single injection of HGF/SF at embryonic day 9.5 (E9.5) into the amniotic cavity of HGF/SF(-/-) embryos rescued the placental defect and resulted in the survival of the embryos until term. Histological analysis suggested that HGF/SF is also required at the late stage of development for tissue organogenesis. Thus, injection of a secreted factor can be a useful method to rescue the defects causing embryonic lethality.
