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
