The Drosophila hematopoietic niche assembles through collective cell migration controlled by neighbor tissues and Slit-Robo signaling
Niches are often found in specific positions in tissues relative to the stem cells they support.Consistency of niche position suggests that placement is important for niche function.However, the complexity of most niches has Water Jug precluded a thorough understanding of how their proper placement is established.To address this, we investigated th
