Recent studies in mice suggest that how the egg cells hold onto and get rid of their proteins may be key to this survival. Although most proteins are renewed every few days, two studies show that some ...

A Japanese researcher has told a major genetics conference that he has created eggs from the ... the unique biology of human gametogenesis (the formation of reproductive cells) to reproduce ...

In a potential breakthrough for infertility and genetic disease treatments, scientists at Kyoto University have succeeded in mass-generating precursors to sperm and eggs from human iPS cells.

FOR the first time, scientists have been able to capture the process of ovulation on video in astounding detail. A breathtaking new clip shows a pulsing egg cell exploding out of its ...

Mirroring the mechanisms that make human faces and bodies—and those of many multicellular organisms—symmetrical, bee colonies ...

This crucial binding, creating 46 pairs of chromosomes, opens the way for cell division, the very beginning of human life. But researchers Dr Jerry Hall and Dr Yan-Ling Feng managed to make eggs ...

For the first time, Oregon State researchers in the US have used cloning techniques to create human embryonic stem ... the nucleus of a donated human egg cell with it. Stem cells have been a ...

The study could serve as proof-of-concept for future fertility treatments aimed at reversing aging in human egg cells — but ...

ACT published the results of experiments using somatic nuclear transfer to produce human embryos. The team fused nuclei from adult cumulus cells—the ovarian cells that surround eggs after ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm ... pluripotent stem cells to mimic the structure and function of a real, growing embryo.

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists ...
