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 …

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 …

It feels like we are marching towards a future in which key aspects of human reproduction, including the use of artificial wombs, could be substantially different than for most of history. The FDA is considering allowing a clinical trial for use of artificial wombs in people. Human trials of artificial wombs could start soon. Here’s …

Researchers have been making stem cell-based embryo models for years now and a few folks have taken to calling these “stembryos.” Other names like gastruloids and blastoids are sometimes used too. “Embryo models” might be the simplest and best name. The embryo model research has advanced relatively quickly from very basic, not very organized structures …

Stem cell biologist Jacob Hanna has a new startup called Renewal Bio. Its goal is to harvest cells or tissues from human embryo or fetus models for clinical use. I believe that their commercial ambitions have so far outstripped careful thought and discussion in the broader community of researchers. There are major risks here for …

I have a soft spot for fibroblasts, perhaps because one of the first immortalized cell lines I ever grew was NIH3T3. These are mouse fibroblasts that have been immortalized. They are very useful for a variety of experiments. I used them to study an oncogene called E2A-PBX1. Experience with fibroblasts including 3T3s I was amazed …

A new word has been added to the lexicon of human stem cell research – blastoids, aka “blastocyst-like structures.” Unlike the familiar three-layered embryo that emerges during the third week of prenatal development, the earlier blastocyst resembles a fluid-filled soccer ball, with a smear of cells on the interior face destined to develop into the …

Today’s The Niche recommended weekly reads post includes both primary papers and also a few media pieces. I’m especially interested in the first piece on making more complex embryo-like structures from ES cells. This is a long way from just making embryoid bodies or EBs. At the end of the post I discuss an article …

Can you make a synthetic embryo, also called an embryo model? 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 …

What with the Mississippi “personhood” amendment up for a vote today and also the Vatican Adult Stem Cell Conference beginning tomorrow, I thought today was a good time for a post about adult versus embryonic stem cells. Does stem cell research have to be either/or? Adult or stem? Can’t someone be for both adult and …
