artificial embryos

2 min read

In this post I list some recent interesting stem cell and science pubs including artificial human embryo research. Engineered human embryo research continues. Scientists for years have been advancing the types of embryo-like structures made from both human and other creature’s cells. In a new Nature Cell Bio pub entitled, “A 3D model of a human epiblast reveals BMP4-driven symmetry breaking”, a team led by Eric Siggia pushed this further. See an image from the paper I’ve included that shows signs of the primitive …Read More

If you are sick of the general news lately, I recommend turning to the wonder of cool science like the thought-provoking data in the duo of new stem cell pubs discussed below including on artificial embryos. Synthetic embryos A team led by Alfonso Martinez-Arias reports new findings in their Nature letter in the growing area of synthetic or artificial embryo-like structures. See my review of a paper on this kind of research from last year. Their new piece Beccari, et al., entitled, “Multi-axial self-organization …Read More

Stem cell news is always burbling up, sometimes right there in front of us on the web and other times via networks of people. Astellas news. Some may remember there used to be this pioneering stem cell biotech called ACT, which then became Ocata, and finally was acquired by the big company Astellas. One of their areas of focus was on using pluripotent stem cells for macular degeneration. The driving scientific force was (and is) Dr. Robert Lanza. About a year ago I had …Read More

Can you make an artificial embryo? Developmental biologist Magdalena Zernicka-Goetz has long been on the trail of this seemingly almost uncatchable quarry. With her team’s publication in Science today they took a big step forward on this path even if some major hurdles remain. You can see her discussion of the research in the YouTube video above along with interesting comments from her graduate student, Sarah Harrison who was the first author. Congrats to both. The paper, Harrison, et al, is entitled “Assembly of embryonic …Read More
