I’ve been closely following the arena of stem cells for COVID-19 since the pandemic broke including the efforts of Mesoblast. Mesoblast unlikely to meet primary endpoints in Phase III COVID trial Now, the firm got bad news as its DSMB reported that they are unlikely to meet the primary endpoint for their Phase III trial of their stem cell product for COVID-19 based on preliminary analyses. Mesoblast had set the endpoint as a “43% reduction in mortality at 30 days for treatment with remestemcel-L.” …Read More

Our mission here on The Niche is primarily educational. We aim to make a transformative difference in educating readers across the globe about stem cells, regenerative medicine, and innovative biomedical science more generally including CRISPR gene editing. Part of that mission involves fact-checking various medical claims about stem cells and other biologics like PRP and exosomes. Another part is battling science and medical hype. What is The Niche blog? The Niche has a global audience and recently surpassed 10 million page views. It is …Read More

Drugs that restore the shape of the errant protein behind cystic fibrosis (CF) have, over the past eight years, helped the majority of patients, who have certain mutations. Gene-corrected stem cells might offer a “mutation agnostic” option to CF. CF results from a glitch in a glycoprotein with the unwieldy name “cystic fibrosis transmembrane conductance regulator”, or CFTR. The proteins normally fold into channels that regulate the flow of ions into and out of cells, controlling the balance of water and salts in linings …Read More

Graft-versus-host disease (GVHD) is counterintuitive In the weeks and months following a transplant, a major concern is the recipient’s immune system rejecting the “foreign” biological material. But in GVHD, the opposite happens: transplanted tissue unleashes a horde of T cells that spark a cascade of inflammation, within 100 days. Typically, GVHD follows a bone marrow transplant (BMT). Eighty Percent Mortality BMT has been used for more than half a century to treat and possibly cure certain cancers and single-gene conditions like sickle cell disease, …Read More

Today’s post is the latest edition of my weekly recommended reads, which this week include Fate Therapeutics, COVID-19 updates, AAMC, and more including some great pubs such as one on 2 modes of PRC2 function. Also check out this handy resource: Helpful 2020 List of Stem Cell Journals and this blast from the past post of 10 years ago: Keep Your Stem Cells Away From BPA. I’ll start with the mid-August 2020 recommended pubs and then go to the media items, but first I wanted to …Read More

In COVID-19, the sense of smell can diminish, vanish, or oddly skew, for weeks or months. The loss usually starts suddenly and is more than the temporarily dulled chemical senses of a stuffy nose from the common cold. As researchers followed up mounting reports of loss of olfaction, a surprising source of perhaps the longest-lasting cases emerged: stem cells in the olfactory epithelium. A Common Symptom Facebook groups may be ahead of the medical literature in providing vivid descriptions of the loss of olfaction …Read More

The Niche has had many authors over the years, focusing on expertise in the biomedical arena and in particular related to stem cells. I’ve invited many authorities in particular areas to write posts. Over the years I’ve written probably 99+% of the posts here on The Niche, but we’ve also had some great guest authors of important pieces. Although you are used to Paul Knoepfler (me) writing most of the pieces, we’ve also had many other authors. Before I give a small bio for each …Read More
