The development of both the mammalian oocyte and the somatic cell compartments of the ovarian follicle is highly coordinated; this coordination ensures that the ovulated oocyte is ready to undergo ...

Researchers have found that a carefully orchestrated act of X-chromosome 'yoyo' predicts the successful and efficient development of mammalian egg cells. The findings could pave the way for generating ...

Figure 1: A colored scanning electron micrograph of ovary tissue, showing a developing oocyte (pink). RIKEN researchers have found that H2A.Z is essential for healthy ...

The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers ...

The new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...

In a new study published in the journal Nature, researchers in Japan report that activating just eight genes for producing gene-controlling proteins is enough to convert mouse stem cells directly into ...

Researchers from Japan and France have successfully reconstituted the development of mouse egg cells, known as oocytes, from embryonic stem cells entirely in vitro, without the need for ovarian ...

This is a preview. Log in through your library . Abstract In starfish a hormonal peptide, gonad-stimulating substance (GSS), which is released from nervous tissue, acts on the gonad to produce a ...

Circadian rhythms are endogenous oscillations widely present in living organisms, typically following approximately 24-hour ...
