Carla Kim & Hans Clevers talks on organoids at #ISSCR2015

liver-organoid

Organoids are pretty big in stem cells right now with the last couple of years having attracted a lot of media attention on mini lungs, mini brains, mini kidneys, mini guts and more, giving the impression that scientists know how to specify and organise cells into mini functional organs in the lab. Organoids have become …

If I only had a brain: brain organoids from pluripotent stem cells

In a first for the field, scientists have used human pluripotent stem cells to grow miniature brain-like structures (brain organoids) in a dish in a lab (see beautiful image of one of these “mini-brains” at left from the paper). This exciting, pioneering feat, accomplished by a team from the Austrian Academy of Science in Vienna …

Sekar Kathiresan, Verve Therapeutics

Some folks can view data from early, small clinical trials too skeptically or overly enthusiastically, and maybe that’s going on with some preliminary results from Verve Therapeutics. Good news? Bad news? I’m going to start with two articles about the same news that have very different vibes. What do I think? On the whole, I …

Sergiu Pasca, assembloid

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. …

Retraction watch

Retraction Watch has been a great resource for those of us who have been following research misconduct. They widely cover and conduct research on retractions, corrections, and other developments in this space. Unfortunately, there’s been plenty to write about even just within the stem cell and cell therapy arena, which is my primary interest. Think …

Human genome sequencing

I wrote earlier this week about genome sequencing of famous dead celebrities, pointing out that the trend seems full of ethical complexities. Genome news More broadly, sequencing the genomes of non-celebrities from hundreds or thousands of years ago can be important research. A new NYT piece covers such work on the Swahili people. Such research …

Stem cell research ethics topics: organoid consciousness & embryo models

brain organoids sm

Someday could human brain organoids get to the point of having organized human-like thoughts? Even consciousness? The more time passes, the less likely I think this is. It’s not impossible, but brain organoids have big limitations in that regard. To be clear, I don’t mean brain organoids having some vaguely human brain-like electrical activity. Even monolayers of …

bat stem cells, stem cells

Occasionally when I write a post there is an angry reaction to it in the blog comments, which was the case for my recent fact-check of the LifeWave X39 patches.  As you can see in that post, I didn’t find convincing data to either back up the claimed stem cell connection. In my opinion, there …

Sam Altman, OpenAI, Chat GPT

Have you had the chance to play around on ChatGPT, the open AI? It can “talk” to you in text kind of like a person. I have tried it out. It’s quite interesting to type in scientific questions and see what pops out. Often it is high-quality text and solid ideas, but not always. You …

H3f3a, histone H3.3, knockout

It’s always exciting when your lab has a new paper and my team just published a study knocking out the H3f3a gene in mice, which codes for histone H3.3 protein. We found that loss of this gene leads to lethality at a late stage of embryonic development. There were also indications of more specific phenotypes …
