Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Changes in cellular metabolites have been shown to regulate embryonic stem cell development at the earliest stages of life. Metabolites are simple compounds generated during life-sustaining chemical ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

The image shows cross sections from four different developmental stages in the early embryo from gastrulation (flat) to the end of neurulation. Unexpectedly, the study revealed that stem cells that ...
