The trouble with the risk of teratoma presents a stem cell paradox. Stem cells possess two traits lacking in other cells: self-renewal and pluripotency. This duo of defining functions is key to the ability of stem cells to be used to treat patients via regenerative medicine. A paradox exists because while self-renewal and pluripotency are both […]

One question I am frequently asked by readers and colleagues is “what other stem cell blogs or bloggers can you recommend that are written by a stem cell scientist and updated on a regular basis?” The simple but surprising answer: there are none. It’s lonely out here in cyberspace! (2020 update: The good news today
How many scientist bloggers does it take to change a light bulb? Read More »
CIRM Board Member, Jeff Sheehy, has a wonderful piece in Nature Medicine on why patient advocates play a critical role in decision making on research priorities (hat tip to Amy Adams who first blogged on Sheehy’s piece). Patient advocates bring a unique and valuable perspective to the table. Their role in guiding CIRM research funding

2020 update: This post from almost 10 years ago on the HIV pandemic and particularly the first paragraph ring differently in the context of the COVID-19 novel coronavirus pandemic. Over the last several years, there has been great concern about a possible flu pandemic around the world, but meanwhile the great pandemic of modern history,

Here an anonymous stem cell scientist frankly answers questions about the field in an interview with me. Of course I have to ask you about the recent U.S. court ruling essentially declaring all federal funding of human ES cell work illegal. What’s your take on this? ANSWER: The ruling has so many flaws in it.

The Obama administration has announced it will “quickly” appeal the ES cell decision, but I’m not hearing anything about a stay on the judge’s order in the meantime or anything like that. It’s quite the opposite. The NIH, in the form of Director Francis Collins, has finally spoken about the federal judge’s ruling that apparently banned

UPDATE: A second recent study, this one in Nature Genetics has found a novel genetic link between the immune system and Parkinson’s Disease. The authors were screening for genomic variants unique to Parkinson’s patients, finding known ones but also a novel linkage. The link was with the HLA region, known to play a key role

UPDATE: I have added more discussion at the bottom about therapeutics and how regenerative medicine might work for Alzheimer’s Disease. Alzheimer’s Disease (AD) is the most common cause of dementia throughout the world, affecting 10s of millions of people. The cost to society is staggering and on a personal level for those of us who

Regenerative medicine is very exciting. But what’s even better than regenerative medicine? Preventative medicine. If one can prevent a problem for occurring in the first place, it is far better than trying to treat it after the fact. Of course in many cases we do not know the causes of diseases so it is difficult
Update in 2020: It seems now after all these years that the consensus in the now more mature field is that IPSCs and ESCs are nearly identical in most cases, and both have some of the same translational challenges such as teratoma-forming activity. It’s interesting to read this post from nearly 10 years ago and
