Oocyte maturation and follicular development are fundamental processes that underpin female fertility. These processes involve the transformation of primordial follicles into a cohort of mature, ...

Baltimore, MD-- Reproduction is highly dependent on diet and the ability to use nutrients to grow and generate energy. This is clearly seen in women, who must provide all the nutritional building ...

One characteristic of oocyte development and physiology that has been a mystery for 60 years is the highly present cytoplasmic lattices within the cytoplasm of mammalian oocytes. These were initially ...

Oocytes are immature egg cells that develop in almost all female mammals before birth. The propagation of future generations depends on this finite reserve of cells surviving for many years without ...

A picture of a mouse MII stage eggs with the location of chromosomes (green) and the distribution of the histone modification H3K4me3 (purple). The team confirmed that H3K4me3 was significantly ...

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 ...

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 ...

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 ...
