Outline of Final Research Achievements

In this study, we searched for novel placenta-related genes from the comprehensive analysis by the microarray using our original cultured cells followed by functional analysis. We obtained eight candidate genes, and two of those showed following interesting phenotypes in mice. The placenta-specific overexpression of candidate gene A caused placental disorder and intrauterine growth retardation. The candidate gene B deficient mice showed multiple abnormalities, placental overgrowth, abnormal delivery and neonatal anemia in the perinatal period. It is expected that these mice are useful as a new recurrent miscarriage model.
