When bioethicist Arthur Caplan talks about stem cells, people pay close attention and for good reason. Caplan has provided important perspectives on the stem cell field over the years. For example, you can see a guest post on this blog here about human cloning. However, in my post today I respectfully discuss how I disagree with several parts of this week’s piece by Caplan on why there are allegedly so many ethical problems in the stem cell research field. Caplan’s article (see screenshot from video at right) is focused on a question articulated by …Read More

What happens if we start using induced pluripotent stem (iPS) cells clinically in humans? A cool new paper recently came out that gets us closer to being able to predict an answer. It’s an important question as iPS cell-derived cellular products are getting closer to clinical use. For example, the first iPS cell-based clinical trial began to enroll patients in Japan last year in a clinical study related to macular degeneration (see my interview with Dr. Masayo Takahashi, who is leading that intriguing study). …Read More

Sometimes there is so much craziness and outright bad stuff going on out there around the world related to stem cells that we can lose sight of all the good news and encouraging developments as well. I think the new paper (Chen, et al.) from a team led by Drs. Lane and Loring is good news. I haven’t had time to fully read it yet, but it reports some encouraging results whereby human neural progenitors injected into the spine of mice with an experimental MS-like …Read More

They say a little knowledge is a dangerous thing and more specifically I say that a little stem cell training for MDs, such as from A4M, can potentially be a dangerous problem too. I’ve been very concerned about self-proclaimed “stem cell training courses” for MDs. These kinds of courses have claimed that over as short as a weekend (perhaps with golf) they fully prepare physicians to do stem cell interventions on patients. Such stem cell-related procedures can yield big profits for physicians, but what about the …Read More
