Tissues rely on stem cells (SCs) for homeostasis and wound repair. SCs reside in specialized microenvironments (niches) whose complexities roles orchestrating tissue growth are still unfolding. Here, we identify lymphatic capillaries as critical SC-niche components. In skin, lymphatics form intimate networks around hair follicle (HF) SCs. When HFs regenerate, lymphatic-SC connections become dynamic. Using a mouse model, unravel secretome switch that controls behavior. Resting express...
To spatially co-exist and differentially specify fates within developing tissues, morphogenetic cues must be correctly positioned interpreted. Here, we investigate mouse hair follicle development to understand how morphogens operate closely spaced, fate-diverging progenitors. Coupling transcriptomics with genetics, show that emerging progenitors produce both WNTs WNT inhibitors. Surprisingly, however, instead of generating a negative feedback loop, the signals oppositely polarize,...
