Germline stem cells
Sex determination and maintenance of the adult sexual phenotype
Development of the early somatic gonad
The mechanisms mediating the development of the somatic gonad in vertebrates during the transition from the sexually bipotential state to the sex-specified state are well defined. In contrast, far less is known about the genes acting earlier during formation of the undifferentiated gonad primordium. We recently discovered that a mutation in a zebrafish Fgf ligand, fgf24, results in the rapid loss of germ cells during early larval development, at a time prior to gonad differentiation. Our results suggest that the primary function of fgf24 is to promote the development of early somatic gonad cells, and that the loss of germ cells in fgf24 mutants is secondary to this defect. We are currently investigating the role of fgf24 in regulating the development of the early somatic gonad.
