D reconstruction of the Sunburst Nuclear Envelope Vesicles. (A) Type III cells. Green sheet = nuclear envelope. Dots = nuclear pore complexes. Purple and red buds = Sunburst Nuclear Envelope Vesicles. (B) Type IV cells. Cyan sheet = nuclear envelope. Dots = nuclear pore complexes. Green, Red, Blue, Purple coral shapes = Sunburst Nuclear Envelope Vesicles. (C) Type V cells. Green sheet = nuclear envelope. Dots = nuclear pore complexes. The rest = Sunburst Nuclear Envelope Vesicles. (D–E) The same Sunburst Nuclear Envelope Vesicle sectioned at different positions. N = nucleoplasm. C = cytoplasm. Ribosomes on nuclear envelope (green sheet) were present but not illustrated. (F–G) The same Sunburst Nuclear Envelope Vesicle viewed from different angles. N = nucleoplasm. C = cytoplasm. Dumbbell shapes in F. (H–I) The same Sunburst Nuclear Envelope Vesicle sectioned at different positions. N = nucleoplasm. C = cytoplasm. Dumbbell shapes in H. Double rings in I.

Here, we identify three novel regulators of #oogenesis in #zebrafish - mTOR, Stat3, and Stathmin, with unpredicted roles in controlling oocyte polarity and formation of the Balbiani body, a conserved oocyte #condensate.

Top: Scheme of an ovariole, oriented from the anterior (A) to the posterior (P) end, as in all the subsequent images. The ovariole starts with the germarium from which young follicles bud before undergoing massive growth until the formation of an egg at the posterior end. In each follicle, somatic follicle cells (in purple) surround a germline cyst with the nurse cells (pink) and the oocyte (in blue). Bottom left: Somatic Inx2A mutant clones, marked by the absence of RFP expression, induce a germline growth defect when they cover the whole epithelium (arrow) compared with the wild-type younger follicle (n − 1) (arrowhead). Bottom right: Maximum intensity projection of immunostaining for Inx2 (green) and Inx4 (magenta) in follicles containing Inx4 RNAi-expressing germline clones visualized by Inx4 absence. Note the absence of Inx2 plaques at germline contacts at higher magnification and the growth defect of Inx4 RNAi follicles (arrow) compared with the wild-type younger follicle (arrowhead).
Gap junctions allow transfer of small molecules between cells. @mirouse-lab.bsky.social &co show that #GapJunctions allow the exchange of metabolites between germ cells & somatic cells to promote germline growth during #Drosophila #oogenesis 🧪 @plosbiology.org plos.io/3CYrZwu

During egg cell development (oogenesis), a germ cell divides into multiple daughter cells. As part of a process that's still something of a mystery, one cell becomes the egg cell, or oocyte, shown here in light micrograph.
Dynamic imaging reveals how egg cells emerge. In PNAS Journal Cub: www.pnas.org/post/journal...
