Most of us have heard of organoids but what about the related model called an “assembloid”, which is a term growing in use including from organoid researcher Sergiu Pasca of Stanford? Before we jump into that, be sure to enter The Niche stem cell image contest for your chance to win $100 or some swag. …
It’s been mostly a downbeat week on the stem cell news front including a deep revisit by Reuters to the Piero Anversa case that has new revelations. It’s ugly stuff involving other folks too. We’ll start on the iPS cell front, where a trial participant had a teratoma. I’ve had a long-standing interest in the …
What happens next to He Jiankui (贺建奎) or as some people now refer to him, the “CRISPR baby guy”? China has a challenging situation to resolve here, but such conflicts between scientists and governments have happened regularly in history. When scientists go “rogue” (i.e. don’t conform to norms or ethical standards in an extreme way or …
New human clinical trials using derivatives of pluripotent stem cells in China for Parkinson’s Disease (PD) have raised expectations and some eyebrows. PD is a neurodegenerative condition, sometimes diagnosed or followed by PET scans such as the one at left, characterized by loss of dopaminergic neurons leading to severe and sometimes life-threatening symptoms. Pluripotent stem …

Rumors have been flying for months that researchers in China and possibly elsewhere were shopping papers around at high-profile journals that reported gene editing and genetic modification of human embryos. Update: apparently this paper (HT to @JohnBorghi) was only reviewed for 2 days (see image at bottom of post), raising major concerns about the depth of …

Cloning of animals is becoming a big, global business, and Hwang Woo-Suk is a major player here. Hwang Woo-Suk and animal cloning It turns out that this reproductive cloning of animals goes well beyond making duplicates of pets for sentimental customers at $100,000 a copy. Cloning of livestock by agribusinesses is becoming fairly common. Some …

In a matter of just a few days we saw three big positive moves against stem cell tourism that will no doubt make a big difference even if there is a long slog ahead against dubious stem cell clinics trying to exploit patients. First, we had the 60 Minutes broadcast on Sunday containing a segment against …

Today is New Year’s Day for the Chinese New Year. Happy New Year! On the Chinese Calendar it is year 4708 instead of 2011. I hope year 4708 is a good one for you and your family. Today being Chinese New Year has got me thinking about how the Chinese view stem cell research. My …

If you remember xenobots, mobile clusters of frog cells, now you might be interested to learn that some of the same team brings us human cell clusters called anthrobots. Both frog and human cellular clusters are considered types of biobots or robots made of cells. To me, anthrobots seem akin to human organoids or assembloids. …

I’m trying to remember the first time I ever heard about clones. It had to be as a kid. Maybe in a monster movie or TV show? Possibly a clone was referred to by the more general term “double”, which is not necessarily a clone. Whatever it was, I’m sure as a kid that I …
