University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

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 — ...

A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

A new study examining mouse embryos when they are composed of just two cells, right after undergoing their very first ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos. Scientists studying gene activity data of the early human embryo have discovered an ...

The early beginnings of an embryo as it transforms from a clump of cells to a tiny human is a bit of a mystery — scientifically speaking. We know many of the broad strokes, but there are a lot of ...

When you seek the help of a fertility specialist to conceive, your first step is to undergo diagnostic tests to understand your likelihood of success. This is followed by a comprehensive consultation ...

Early in development, all animal embryos pass through an almost identical stage where they form a blastoderm, which is a hollow ball of a few thousand cells. From that hollow ball, layers of cells ...

LONDON (Reuters) - A new high-powered microscope has allowed scientists to watch a zebrafish develop from a single cell into an embryo with a beating heart, the first time this has been possible in ...
