During development, gonads arise from bipotential progenitors capable of developing into either testes or ovaries. I am interested in how individual cells within the bipotential progenitor adopt either a testis or ovary cell-fate and how this decision is coordinated among groups of cells during organogenesis. In the Albrecht lab, we employ a mouse model in which XY mice heterozygous for either Wt1 (Wilms’ tumor 1) or Sf1 (Steroidogenic factor 1) null alleles develop ovotestes or ovaries instead of testes. We are investigating the molecular and cellular mechanisms of sex reversal in these mice to further define the roles of Wt1 and Sf1 in testis development.
