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

What is status of research on Stem Cells in China 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

For a few years, biophysicist He Jiankui might have been one of the most recognizable scientists on the planet. He made three “CRISPR babies” or gene edited people. However, his gene editing went badly and as best as we can tell his efforts did not result in precision edits. It’s unclear if he had institutional
How are things going with regenerative medicine and stem cells in Japan? It’s still an exciting time there, but I’ve noted a sense that it is a time of transition too in some ways. For example, government funding is perhaps less certain than in the past. Let’s start with a few articles on how the
