The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the ...

A stem-cell derived human embryo model showing blue cells (embryo), yellow cells (yolk sac) and pink cells (placenta). Scientists have grown an entity that closely resembles an early human embryo ...

"Zebrahub" is an atlas of cells in developing zebrafish embryos, and scientists say it will help us learn about our own ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed ...

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 have ...

Upon its debut, non-reproductive biomedical applications of synthetic embryos were widely touted. For example, synthetic ...

In 2021, the Nobel Prize in Physiology or Medicine was awarded for elucidating the biology of mechanosensors. These ...

In 2005, the National Academies released the book, Guidelines for Human Embryonic Stem Cell Research, which offered a common set of ethical standards for a field that, due to the absence of ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi ...
