Research Abstract
Long distance communication between cells is essential for development and homeostasis. Such signaling depends on the diffusion of secreted factors, yet additional modes of communication have been uncovered including direct contacts between cells mediated by long, specialized filopodia. We found that stripes in zebrafish require a novel class of thin, fast projection with vesicles at their tips named “airinemes” that contribute to transducing a Delta-Notch signal over long distances from precursor cells of yellow-orange xanthophores to target melanophores. Interestingly, pigment cells are not the only cell type that extends airinemes. We have found them from many other cell types.
Also, we show that macrophages play critical role in airineme-mediated signaling by relaying the airineme vesicles to the target cells. Our study reveals a novel mechanism of cellular communication and, suggest airinemes are widely used in various tissues during normal development and disease.
