Weekly reads: teratoma in iPSC trial, Piero Anversa & friends, Athersys, China Initiative

Dr-Piero-Anversa

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 …

When the state & ‘rogue’ scientists collide: case of China & CRISPR baby guy He Jiankui (贺建奎)

He-Jiankui-贺建奎

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 …

How risky are stem cell trials for Parkinson’s beginning in China?

Brain-PET-scan, stem cells

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 …

Researchers in China make genetically modified human embryos

Liang-P.-et-al.

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 Factory in China Has Familiar Partner: Hwang Woo-Suk

cloned-babies

Cloning of animals is becoming a big, global business. 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 are also trying to de-extinct woolly mammoths by cloning too, something that I …

A trifecta of wins against stem cell tourism: 60 Minutes, FDA, and China

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 …

stem cells for ALS treatment

A new stem cells for ALS treatment trial represents a big step forward. It’s early days still but this trial shows feasibility and provides a helpful foundation for moving forward. It also highlights challenges. The work is from a team led by Clive Svendsen. Stem cells for ALS treatment trial Here’s the study. Transplantation of …

Weekly stem cell reads: aging & cells, iPS cell mutations, gut, more

Stem cells aging

Does aging do something to time so it seems like as you get older that time goes by faster? Remember as a little kid when summer seemed to last forever and car rides could be agonizingly long? I’ve heard two theories on this. One is that the brain’s baseline of activity slows down with aging …

Weekly reads: Yale scientist suspended, WA AG sues clinic, new pubs

Dr. Tami Meraglia has been sued by the Washington State AG for selling unproven stem cells.

It’s very challenging to be an academic scientist even under normal circumstances so when a government starts going after researchers for things like supposed irregularities in funding disclosures, it can cause serious problems if not carefully overseen. We’ll start this week’s recommended reads with the feds monitoring such disclosures and even making referrals to the …
