What does homologous use mean? Navigating the arena of clinical use of a biologic such as stem cells or differentiated cells made from stem cells can be challenging. There are many important issues including what defines “minimal manipulation” of biologics such as cells. One particular issue that is critically important and has drawn less attention […]

Are MUSE cells for real? Stem cells come in different types that vary in a key property called “potency”, but very few are pluripotent. The more potency, the greater the flexibility of a stem cell to make other cell types. Flexibility in the cellular world is power. The most powerful stem cells generally used are
Jury is still out on purported adult pluripotent stem cells despite new MUSE paper Read More »
I recently did a post and a poll on whether a blogger scientist should blog about a very weak, but sexy paper from a famous, powerful scientist in the stem cell field whom I called “Dr. Famous”. The poll is still getting a lot of responses so I’m not going to discuss the results yet

What is stem cell self-experimentation? A concerning trend in the for-profit stem cell field, but one that does not get enough attention, is self-experimentation by those selling (often unlicensed) stem cell treatments. In other words, the stem cell clinic leaders and docs often not only sell stem cell treatments to patients, but also they give themselves

Just how safe are stem cell transplants? Is an autologous stem cell transplant always safe? Is it really true, as one stem cell transplant doc once said of autologous stem cell treatments, that “the worst thing that could happen is the treatment won’t work”? Are adult stem cell treatments by definition safe? The reality is

A big issue in the stem cell field is that firms increasingly are doing business in multiple countries. Associated with the increasingly international nature of the stem cell for-profit industry are emerging legal and ethical issues related to the transport of stem cell-based biological drugs across international borders. Think you can just FedEx human stem
Writing this blog I hear a lot of stuff about stem cells all across the globe. Some of this is noise, but some is signal (i.e. real). What seems to be a very real and worrisome trend is that unlicensed for-profit treatments in the Philippines have exploded in the last two years. I would characterize

Today the Supreme Court announced it would not hear the Sherley v Sebelius case, ending the court battle that has left embryonic stem cell research (ESCR) in what I’ve called a “big chill”. This is great news. It is all over the mainstream media. Even the rampant anti-science, pro-lifers have declared defeat. I’m not going

I’ve received such a huge response (more than 20 nominees) for the Knoepfler Lab Stem Cell Person of the Year Award and the nominees to date are so awesome that I’ve decided for practical purposes to end the nomination period a bit earlier than originally planned. Thus, tomorrow Dec. 13 will be the last day
What’s the big deal about unproven stem cell treatments, patients often ask me. Why should patients avoid these? Because paradoxically such treatments, intended to cure disease, can have devastating negative consequences for your health. I’m doing an eight-part series, “Eight simple reasons not to get a stem cell treatment”. The first two blog posts were
