To determine how Decapentaplegic signaling is spatially restricted within the Drosophila ovarian niche to balance stem cell self-renewal against differentiation.
Examined cellular crosstalk and signal transduction between female germline stem cells and neighboring somatic niche cells in Drosophila melanogaster.
Investigated the regulation of epidermal growth factor receptor-mitogen-activated protein kinase (EGFR-MAPK) signaling and downstream dally expression in somatic cells.
Germline stem cells activate somatic EGFR-MAPK signaling, which represses the expression of the glypican-encoding gene dally required for DPP movement and stability.
Restricting DPP diffusion confines high signaling activation exclusively to niche-adjacent stem cells, enabling displaced cystoblasts to experience lower signaling and initiate differentiation.

Implication

Experimental study reveals reciprocal germline-soma signaling restricts DPP activity in Drosophila ovaries, indicating how stem cells self-regulate their physical niche boundaries.
