Gap junctions allow transfer of metabolites between germ cells and somatic cells to promote germ cell growth in the Drosophila ovary

Gap junctions allow transfer of small molecules between cells, but it is unclear if cells can use this process to promote cell growth. Here, the authors show that gap junctions allow the exchange of metabolites between germ cells and somatic cells to promote germline growth during Drosophila oogenesis.

Sequential events during the quiescence to proliferation transition establish patterns of follicle cell differentiation in the Drosophila ovary

Summary: Epithelial follicle stem cells in the fly ovary depend on dynamic, axon-like cytoplasmic projections to re-establish cell fate patterning after a period of nutrient restriction.

Excited to share that our study on how cell-cell affinity between two cell lineages locally controls cell shapes and globally drives self-organization of an entire tissue is out now in Nature Communications.

Eya-controlled affinity between cell lineages drives tissue self-organization during Drosophila oogenesis - Nature Communications

Oogenesis depends on close interaction between germ cells and the surrounding somatic niche. Here the authors demonstrate that Eya controls bilateral affinity at the germline-soma interface to generate self-organizing inter-lineage units that ensure oocyte maturation.
