Skepticism on the Bryan Johnson anti-aging extravaganza

Oliver Zolman, Bryan Johnson

Near-billionaire Bryan Johnson apparently does not like getting old and he’s trying to do something transformative about it. He and his team are experimenting in a big way.  As a 55-year-old myself, I can’t blame him for wanting to fight aging in general. However, his anti-aging project includes some extreme stuff. Will some in the …

3rd Invitrx warning highlights FDA oversight weakness

The FDA seems oddly slow in oversight of unproven stem cell clinic-related firms like one here in California called Invitrx Therapeutics. I’ve written before about Invitrx, but interactions between them and the FDA have continued including a new warning letter. It’s become a puzzling situation. More broadly, the FDA has done relatively little in the past …

Grading my 2022 regenerative medicine predictions

stem-cell-crystal-ball-300x3001

It’s that time of year again when I grade my previous year’s predictions for the stem cell & regenerative medicine space. Overall, I did better than a typical year. I give the 2022 predictions an A- overall. This exercise can be kind of fun but also humbling. For example, I tend to be too optimistic …

2nd chances after big misconduct? He Jiankui, James Wilson, others

James Wilson, Gene therapy

There have been rare instances like with scientist James Wilson where researchers were involved in what I would call major misconduct but somehow managed to bounce back. In a sense, they were given second chances in part by regulators but also by other scientists or supporters. However, after extraordinary misconduct, especially contributing to the death …

Review of ExoFlo paper used to push Direct Biologics IND inside FDA finds red flags

ExoFlo from Direct Biologics

I wrote recently about how political pressure on FDA Commissioner Stephen Hahn in 2020 may have helped the Texas firm Direct Biologics move their product ExoFlo forward inside the agency. Today I analyze the ExoFlo Phase I clinical trial paper used in that push on Hahn to get the firm the IND for a Phase II …

What is HSCT & its possible roles in MS treatment?

Selma-Blair-HSCT

Patients regularly reach out and ask me about something called HSCT. “What is HSCT?” and is it proven as a therapy? Often the patients asking about this have multiple sclerosis (MS) or some other autoimmune disease. I’m not a physician so I can’t give medical advice, but as a stem cell biologist here at UC …

FDA leader Stephen Hahn was pressured to aid Texas firm Direct Biologics

Former FDA Commissioner Stephen Hahn.

An FDA FOIA dump of text messages of former Commissioner Stephen Hahn suggests that a Texas regenerative firm called Direct Biologics benefited from political pressure on him in mid-2020. Then he was asked again to help in early 2021. This was shortly before he resigned at the start of the Biden Administration. The push came from …

‘We don’t want to freak people out’: about that Jacob Hanna human embryo model startup

Jacob Hanna Renewal Bio

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 …

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 …

Weekly reads: $1B Saudi anti-aging push, OCT4 necklace, cancer trial wows, coffee brain

Stem-Cells-Aging, anti-aging

I recently wrote about stem cell-related ideas for anti-aging and even cheating death, but there are of course other approaches including drugs like metformin. A new article outlines a massive research funding plan to tackle aging. Let’s start with that. Recommend reads including anti-aging Saudi Arabia plans to spend $1 billion a year discovering treatments to …
