The transmission process of Sex Ratio Organisms (SROs) into oocyte during oogenesis in Drosophila melanogaster was studied by electron microscopy. SROs break through a tunica propria, a non-cellular membrane surrounding the egg chamber, and move toward oocytes passing through the intercellular space of the follicle cell layer at previtellogenic stages. After reaching at the surface of an oocyte...
Abnormalities in ovarian function, including defective oogenesis and folliculogenesis, represent a key female reproductive deficiency. Accumulating evidence in the literature has shown that the PI3K/PTEN/Akt and TSC/mTOR signaling pathways are critical regulators of ovarian function including quiescence, activation, and survival of primordial follicles, granulosa cell proliferation and differen...
Background and Objective: Oogenesis is a process of sexual reproduction in many animals. Some medicinal plants are effective in the process of evalution and pregnancy and some others cause disorders. The Juniperus Sabina is a species of Juniperus which is used in traditional medicine as an abortive. Therefore, we decided to examine the effect of the essence of Juniperus Sabina’s fruit...
Abstract Extracellular vesicles (EVs) are bilayer-membrane-bound isolated from biofluids and tissues. Recently, these organelles have been recognized as a novel mode for inter intra-cellular communication. The three critical subtypes of EVs include exosomes, microvesicles, apoptotic bodies. They can be discriminated according to their size, cargo, biogenesis, release pathways, functions. These ...
