The causes of embryonic arrest during pre-implantation development are poorly understood. Attempts to correlate patterns of oocyte gene expression with successful embryo development have been hampered ...

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 ...

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 ...

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 ...

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 ...

Experts in in-vitro fertilization (IVF) from UC San Francisco have discovered a pattern of protein secretion during egg maturation that they say has the possibility of leading to a new, non-invasive ...

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

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 ...
