Paolo Macchiarini is one of a small group of people in the stem cell universe whose misconduct has blown up in the press. Piero Anversa, Haruko Obokata, Hwang Woo-Suk, and some operators in the unproven stem cell clinic sphere come to mind. Macchiarini published quite a few seriously problematic papers, some of which just hung […]

CRISPR gene editing has made rapid progress heading from bench to bedside. Perhaps the fastest has been its progress toward clinical use to combat sickle cell disease. We’ll start with a new paper on one major effort here. CRISPR gene editing. This process often involves cutting DNA, which then can be used as an opening to

Early during my postdoc I was primarily interested in the role of Myc genes both in cancer and in stem cells, work that later included embryonic stem cells. These cells are often called ES cells. At first I first started studying N-Myc in neural stem cells using a conditional knockout approach. However, soon after I was

A days ago the news came about Mesoblast not getting FDA approval for its MSC product for GvHD. The MSC area has had a rough few years with various clinical trials including for COVID. The “stem cells for heart disease” arena has also had a tough time. Here’s more news along these lines: BioCardia pauses enrollment in PhIII trial

It’s great finding stem cell videos on YouTube that are either excellent research talks or provide important information. I recently found one such video by Shiri Gur-Cohen, which I included below. Interesting data there and Shiri is such a compelling speaker. She also won The Niche image contest one year with a cool microscopy pic

Who is David Sinclair and why is he all over the media related to anti-aging efforts? This post is my effort to fact-check Sinclair’s statements in the context of the broader rejuvenation arena. In the process I also review his most recent paper from my view as a stem cell and cancer biologist interested in

It’s mostly been a week of good and encouraging news in the regenerative medicine space including with gene therapies maybe with the exception of some eye drops warnings (more below). There’s realistic hope for an approved sickle cell disease soon. I also see some long-term positive news on hearing loss research. Hematopoietic stem cell transplant

About twenty years ago a science story made big news of a so-called anti-aging Methuselah gene. Methuselah gene and anti-aging The claim was that this DNA conferred long life on people. Hence the name Methuselah, which refers to a man from the Bible who reportedly lived 969 years. The so-called Methuselah gene was at first not a

Out of the blue this past week we lost Kevin McCormack of CIRM to a heart attack. When I first heard, my reaction was that can’t be, but it is. About Kevin McCormack If you aren’t familiar with him, Kevin was officially Director of Patient Advocacy at our state’s Stem Cell Agency. However, he was

We’ll start with a story related to possible research misconduct, Stanford’s President Marc Tessier-Lavigne, and Science Magazine. In some ways the news on Science itself could be the bigger long-term story. Marc Tessier-Lavigne pub investigation, Science oops moment Here’s some of the coverage: Stanford investigates potential misconduct in president’s research, Science.
