Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Timelapse of a gene-edited medaka fish embryo undergoing mitosis. The mitotic spindle – the green strands in the middle of the cells – can be seen aligning and segregating duplicated chromosomes, ...

Scientists have created embryo models to help study the mysteries of early human development, the medical problems that occur before birth and why many pregnancies fail. These models are made from ...

The study revealed unexpected and sex-specific effects of germline regulation on longevity and somatic repair in vertebrates. Contrary to classical evolutionary theories, it turns out that changing ...

The International Society for Stem Cell Research (ISSCR) Embryo Models Working Group has released updated recommendations for the oversight and regulation of stem cell-based embryo models (SCBEM), ...

Studying chemical chatter as tiny balls of cells embed could shine a light on early pregnancy and glitches that lead to miscarriage Researchers have created the lining of a womb in a dish, which ...

Embryos hold the secrets of regeneration, reproduction, and maybe even human immortality. This article first appeared in The Checkup, MIT Technology Review's weekly biotech newsletter. To receive it ...

Stem cell-based embryo models (SCBEMs) are three-dimensional biological structures that mimic aspects of early human embryo development. They can be created in the lab from stem cells, and can provide ...

Scientists have created human eggs in the lab using a similar process to the one used to clone the famous Dolly the sheep, then used in vitro fertilization (IVF) to turn them into embryos. Although ...
