RelevancePiwi mediates a somatic signaling mechanism required for the maintenance of germline stem cells to produce and maintain a daughter germline stem cell. It is not essential for the further differentiation of the committed daughter cell. Acts cell autonomously to promote germline stem cell division. It is expressed somatically in the ovariole terminal filament and epithelial sheath cells. Expressed in the germarium at low levels during oogenesis stages 1-6, at a lower level during stages 7-9, strongly at stage 10 and eventually accumulating in early embryos.
