Scientists launch clinical trial of CRISPR gene correction therapy in patients with sickle cell disease

Scientists at UC San Francisco, UC Berkeley and UCLA have received U.S. Food and Drug Administration approval to jointly launch an early phase, first-in-human clinical trial of a CRISPR gene correction therapy in patients with sickle cell disease using the patient's own blood-forming stem cells. The trial will combine CRISPR technology developed at Innovative Genomics

Scientists identify a possible new treatment for diabetic retinopathy

About one in three diabetic patients develops diabetic retinopathy (DR), which can impair vision and lead to blindness. A new study in The American Journal of Pathology, published by Elsevier, provides clear evidence that high glucose increases the levels of enzymatic precursor — lysyl oxidase propeptide (LOX-PP) — that promotes cell death, which was verified

Pancreas on a chip: Organ-on-a-chip and stem-cell tech combined: Organ-on-a-chip and stem-cell tech

By combining two powerful technologies, scientists are taking diabetes research to a whole new level. In a study led by Harvard University’s Kevin Kit Parker, microfluidics and human, insulin-producing beta cells have been integrated in an “Islet-on-a-Chip.” The new device makes it easier for scientists to screen insulin-producing cells before transplanting them into a patient,

Scientists identify potential cause of statin-related muscle pain: Moderate exercise an antidote to known statin side effect

An international team of BHF-funded researchers may have discovered why some people experience muscle pain after taking statins. The research, published in JACC: Basic to Translational Science, could help doctors prevent a known side effect of statins and ensure people are able to reap the benefits of the life-saving drugs. According to the research, statins

Certain metabolites linked to stem cell function in the intestine: Molecules called ketone bodies may improve stem cells’ ability to regenerate new intestinal tissue

MIT biologists have discovered an unexpected effect of a ketogenic, or fat-rich, diet: They showed that high levels of ketone bodies, molecules produced by the breakdown of fat, help the intestine to maintain a large pool of adult stem cells, which are crucial for keeping the intestinal lining healthy. The researchers also found that intestinal

Helping transplanted stem cells stick around and do their jobs: New microgel encapsulation method paves the way for more efficient cell therapies

Bone marrow transplants of hematopoietic stem cells have become standard treatment for a host of conditions including cancers of the blood and lymphatic systems, sickle cell anemia, inherited metabolic disorders, and radiation damage. Unfortunately, many bone marrow transplants fail due to rejection by the patient’s immune system or graft-versus-host disease (in which the transplanted marrow

Molecular scissors stabilize the cell’s cytoskeleton

Researchers at the Paul Scherrer Institute PSI in Villigen, Switzerland, have for the first time elucidated the structure of important enzymes in human cells that alter essential building blocks of the cellular cytoskeleton. This reveals the missing part of a cycle that regulates the build-up or breakdown of supporting elements of the cell. The enzymes

How hepatitis B and delta viruses establish infection of liver cells: Researchers explore infection using new cell culture system

Princeton University researchers have developed a new, scalable cell culture system that allows for detailed investigation of how host cells respond to infection with hepatitis B (HBV) and delta virus (HDV). The paper describing their findings was published online on June 18, 2019 in the journal Hepatology. HBV causes an acute illness that is usually

New method for engineering metabolic pathways: Two approaches provide faster way to create complex molecules

Cells are incredibly adept at creating complex molecules, like therapeutics, and can do so much better than many of our best factories. Synthetic biologists look to re-engineer cells to make these molecules for specific needs, including pharmaceuticals and energy applications. But the trial-and-error process is difficult and time-consuming, and often competes with the cell’s other

New strategy of reprogramming regulatory T cells may improve cancer therapies: Converting immunosuppressive cells into inflammatory cells appears to prime tumors for immune checkpoint blockade

While therapies that harness the power of the immune system against cancer have made remarkable progress against certain types of tumors, they still remain ineffective in most cancer patients. A new study from the Center for Immunology and Inflammatory Diseases (CIID) at Massachusetts General Hospital (MGH) describes a method of reprogramming the regulatory T cells

Targeted therapy proves effective against aggressive rare blood cancer: Clinical study treating BPDCN with tagraxofusp led to first FDA approval for the disease

A multi-institutional clinical trial has given good results for a targeted therapy to treat a rare, aggressive blood cancer known as blastic plasmacytoid dendritic-cell neoplasm (BPDCN). Details on the trial, which supported Food and Drug Administration approval of the tagraxofusp therapy in December 2018, have been published in the New England Journal of Medicine. Diagnosed

What Are Stem Cells?

The term "stem cells" has become part of the mainstream lexicon, likely to be overheard in conversations anywhere from a baseball game to cocktail get-togethers. But what exactly are these cells? Along with phrases such as "that's just immoral" or "stem cells could be the end-all cure," one could easily weave in some technical tidbits
