Characterization of the Drosophila Egfl7/8 ortholog during oogenesis
… the 14 stages of oogenesis moving from the germarium toward the oviduct. For the mature egg to be formed cell death has to occur at specific stages both in the germline (nurse cells) and in the somatic cells (follicle cells). However, whether this apoptosis is caused by intrinsic or …

Drosophila Ovarian Stem Cell Establishment is Regulated by Nuclear Hormone Receptor ftz-f1
… for proper movement of germ cells out of the germarium in adult stages. Taken together, we suggest ftz-f1 function during juvenile stages is critical for the establishment of GSCs and development of their progeny.

Wolbachia colonization in drosophila midguts and its effects on intestinal stem cells
… pathogenic strain wMelPop increases ROS in the germarium, while the symbiotic strains wMel and wMelCS reduce ROS in the terminal filaments. None of the Wolbachia strains tested affected ROS levels in the testes. In addition, genetically altering ROS levels in the germline or systemically in the …

Isolation and characterization of the B-type allatostatin gene of Gryllus bimaculatus de Geer (Ensifera, Gryllidae)
… ganglia, and the abdominal ganglia. In the germarium and in primary oocytes of the ovary, Grybi-AS B gene expression was detected as condensed signals in the nuclei, but not in the prefollicular cells or the cytoplasm. With ongoing development of the oocytes, the signals in the nuclei …

Deciphering the Functional Collaboration of Mid and bric-a-brac 2 as Potential Regulators of Cellular Proliferation Within Adult <i>Drosophila</i> Ovaries
<p>Stem cell niches are highly organized and specialized microenvironments located within specific tissues of both vertebrate and invertebrate organisms [1]. In <em>Drosophila melanogaster</em>, three distinct stem cell niches have been identified within the ovary including the germline stem cell …
