Scientists are using human stem cells to create a structure that mimics a pre-embryo and can serve as a research alternative to a real one. They say these “blastoids” provide an efficient, ethical way ...

Researchers at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at the ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

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 — ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

(a) FISH of pre-18S and pre-28S rRNA in mouse early embryos. Yellow triangles indicate pre-rRNA signal within the NPB or nucleolus. Scale bar, 20 μm. (b) Fluorescence of CYTO signal in mouse early ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...
