Research Abstract

We have identified fetal Leydig cell-specific enhancer of the Ad4BP/SF-1 gene, and established the mouse lines in which EGFP or Cre is expressed specifically in the fetal Leydig cells. In order to identify mRNA expression profile of the fetal Leydig cells, we performed cell sorting and microarray analyses. In addition, we intercrossed Cre-expressing mice with the SF-1 flox mice, and generated the fetal Leydig cell-specific Ad4BP/SF-1 KO mice. From the analyses of these mice, we have identified that Ad4BP/SF-1 is essential for the function and differentiation of the fetal Leydig cells, and also for the masculinization of the fetuses.
