My lab is focused in part on chromatin states in stem cells and cancer including heterochromatin. In fact, my lab’s website is chromatin.com. Heterochromatin is dense, often inactive chromatin. By H&E staining and electron microscopy, heterochromatin looks dark compared to the rest of the nucleus, largely composed of euchromatin. Toward the end of my postdoc …

I’ve been following 24 stem cell stocks for a few years. I haven’t invested in them or any others recently, but rather just find them interesting. How are these doing in 2023? Mostly not great. In some cases, it is downright disastrous. Let’s take a quick look at four stocks very much in the news over …
Australian biotech Mesoblast has had a rollercoaster ride working toward FDA approval of its mesenchymal cell therapy product remestemcel-L. They are seeking approval for use in patients with graft-versus-host disease (GvHD). More specifically, it is intended for pediatric patients with steroid-refractory acute graft versus host disease, or SR-aGVHD. This is a serious condition and new treatment …

Where do things stand with potential applications of CRISPR and other gene editing technologies in patients? Overall, things are looking very positive. CRISPR human trials This week the third big international human genome editing meeting took place in London. The summit addressed numerous potential clinical applications. It was good to see the agenda included quite …

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 …

The biotech Mesoblast is starting an expanded access study of its stem cell product for kids with a severe offshoot of COVID-19. The cellular drug in this case is remestemcel-L (more below). While most children fare better than adults in dealing with COVID-19, the rare subset of kids with COVID-19 for this study have more severe …
It’s been a busy week for the cellular and regenerative medicine space for COVID-19 news with some possible ups including for Mesoblast and some definite downs. Starting with the more positive media buzz with have Mesoblast.

Could two stem cell biotechs Athersys and Mesoblast help in the battle against the novel coronavirus disease COVID-19? Stem cells, ARDS, and COVID-19 I’ve already written two pieces about the idea of using stem cells to battle COVID-19 (here and here), the sometimes fatal disease that arises from infection with the novel coronavirus. Older patients …
