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

For a long time at the end of each year, I’ve been making stem cell predictions for the coming year. Most often I’ve been making a “top 20” list of predictions and today’s post has my list for 2019. You can see how I did for 2018 here, which might have been my best year ever for predictions. We’ll see if I can match that here for 2019. I doubt it. However, I do think my prediction that 2019 will be the worst year …Read More

Here are some stem cell reads for the weekend, ranging from media to research articles. TGIF! What are your stem cell or other science weekend reads? Let’s start with how difficult it is to make IPS cells from naked mole rats! Naked Mole Rat Cells Have a Stable Epigenome that Resists iPSC Reprogramming. It takes more than OSKM to make naked mole rat IPSCs. Throwing in SV40 LT helps, etc. Regeneration is cool & we are getting to understand it better, Study first to identify the cells …Read More

The debate over whether the main conclusions of the Nature paper on human embryo CRISPR led by Shoukhrat Mitalipov’s lab at Oregon Health Sciences University (OHSU) are correct remains unresolved. Note that Nature just added an editorial alert just above the references section to their paper: “Updated online 02 October 2017. Editorial Note: Readers are alerted that some of the conclusions of this paper are subject to critiques that are being considered by editors. Some of these critiques have been publicly deposited in preprint form. A further …Read More
