Interviews with leaders and top players in the stem cell field

I’ve been fortunate to interview some of the greats in the stem cell field for this blog and host debates between key players. Please note that just because I have interviewed folks does not mean I agree with them or that they agree with me. The point is to establish dialogue on key issues. As […]

iPS cells are similar to cancer cells: part 1 of discussion of new paper

My lab just published a somewhat provocative paper (still in unproofed form at this point) arguing that iPS cells are very similar in some ways to cancer cells. How did we get to that conclusion (discussed in this post today, part 1 of the story) and what’s the back story on this paper (discussed in a later

Catherine Verfaillie retraction, Catherine Verfaillie

When I was first really getting into stem cells as a trainee the name Catherine Verfaillie came up as a scientist to watch in the adult stem cell area. It wasn’t too long after that though that I started hearing that some of the work from her lab at the University of Minnesota was being

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

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

Vacanti Mouse

Eight years ago two new Nature papers broke on the scene reporting supposed STAP cells with one of the senior authors, Charles Vacanti of Harvard, most well known previously for making the so-called “Vacanti mouse” along with his brother Joseph. The Vacanti mouse had a bioengineered human ear growing on its back. While STAP cells

Dont-mess-with-mother-nature

When I was a kid there was this commercial on TV for Chiffon margarine (fake butter) with the slogan, “It’s not nice to fool mother nature!” As a kid I thought it was dumb but kind of funny. A modified version of that mother nature advertising slogan has become a cultural tagline. Don’t mess with

History tells us to be more skeptical of He Jiankui’s CRISPR baby story

Fake-cloning

Could He Jiankui have faked part or all of his CRISPR babies story? If so, how? Why? Or to put it another way, almost everyone seems to be assuming the story is real, but should we be more skeptical? Should we flip things around and assume the story isn’t entirely kosher until proven otherwise? I once
