Today’s post takes a close look at the exosome manufacturer Kimera Labs in the context of the main exosome companies. What are exosomes?

It’s funny how sometimes there are many new articles about one general topic like this week with heritable (and somatic) human CRISPR gene editing and related tech. There are clear reasons for optimism in the somatic arena given advancing trials. Germline editing remains highly questionable in my view even just technically. Then there are loads …

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 …

Let’s start with a couple of new pieces on in vivo reprogramming. The idea here is to do something like making iPS cells but doing it inside organisms and not quite pushing cells all the way back to pluripotency. Just younger, healthier cells. Why do that? The goal is to achieve a kind of anti-aging …

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 …

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 …

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 …

When you are a stem cell biologist and especially if you do a blog, you sometimes run across very strange things like a chimera cat. In this case, I stumbled on the whole topic of chimeric cats because I was searching for info on chimeric rats on Google. Of course, I was. It’s kind of …

The last six months I’ve been spending even more time than usual writing NIH grants (and a few others). The last two weeks have been especially busy on this front as I am getting an R01 renewal out the door. My paper reading lately has been mostly related to the grant writing I’m doing. Still, …
