Researchers have taken a major step towards creating synthetic embryo-like structures that mimic real human embryos with most of the fundamental features of the earliest stages of life. The latest ...

A calf was born from an embryo lacking cells which form a large part of the placenta, providing new insight into the regenerative capacity of mammalian embryos. Mammalian development starts from a ...

As nearly one in six couples experience fertility issues, in-vitro fertilization (IVF) is an increasingly common form of ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

University of Pittsburgh researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells.

Ireland's Catholic bishops have rejected 31 of the 40 recommendations of the Government-appointed Commission on Assisted Human Reproduction. In a statement issued at the end of their three-day winter ...

A team of scientists have successfully created authentic models of a human embryo using stem cells, and successfully grown them outside of a womb until key embryonic features such as a yolk sac, and ...

Scientists have created synthetic human embryos using stem cells, in a groundbreaking advance that sidesteps the need for eggs or sperm. Scientists say these model embryos, which resemble those in the ...

HeX-Embryoid model showing early blood cells (green) that have formed inside of blood vessels (red) surrounded by yolk sac mesoderm cells (blue) that support these tissues. University of Pittsburgh ...
