... mediates dietary maintenance of Drosophila ovarian germline stem cells (GSCs) by promoting the extension of niche escort cell (EC) membranes to wrap around GSCs. This wrapping may facilitate the delivery of bone morphogenetic protein stemness factors from ECs in the niche to GSCs. In addition...

... integration involves escort cells (ECs), which promote differentiation of the GSC derivatives they envelop, provide niche signals for FSCs and derive directly from FSCs in adults. Hedgehog (Hh) signaling induces the Hippo pathway effector Yorkie (Yki) to promote proliferation and maintenance of FSCs, but Hh...

... embryonic development, but whether this function module has a role in adult tissues is unclear. Here, we report that in the Drosophila ovary, disruption of the Polycomb repressive complex 1 (PRC1), specifically in the supporting escort cells, causes blockage of cystoblast differentiation and germline stem...

... physically with escort cells (ECs). It has been proposed that escort stem cells (ESCs), which directly contact GSCs, generate differentiated ECs to maintain the EC population. However, it remains unclear whether the differentiation status of germ cells affects EC behavior and how the interaction between ECs...
