Human Stem Cell-Derived Retinal Organoid Sheets Close Macular Holes

Researchers reported in the journal Stem Cell Reports that retinal holes in a monkey model were successfully healed by transplanting human stem cells. Following transplantation, retinal tissue was continuously added to the macular holes to seal them.

Harnessing the Power of Beneficial Bacteria to Fight Enterobacteriaceae

Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enterobacteriaceae are a common cause of these infections and have few treatment options. Fecal microbiota transplants have shown promise to curb some of these infections, but their composition varies between batches and they aren't always successful.

Study Reveals Immune Cells' Role in Lung Scarring After Viral Infections

Investigators involved in a multicenter study co-led by Cedars-Sinai discovered a pathway by which immune cells prevent the lungs' protective barrier from healing after viral infections like COVID-19.

Inflammation-Induced Epigenetic Changes Limit Intestinal Stem Cell Regeneration

Researchers from the University of Michigan, Baylor College of Medicine, and other affiliated institutions have found that intestinal stem cells (ISCs) are permanently altered by inflammation in the gut, which limits the cells' capacity to repair the gut even after the inflammation has subsided.

Melbourne Researchers Achieve Breakthrough in Creating Human-Like Blood Stem Cells

Melbourne researchers have made a world first breakthrough into creating blood stem cells that closely resemble those in the human body.

Research Unlocks Secrets of Stem Cell Retention in Bone Marrow

A discovery by a three-member Albert Einstein College of Medicine research team may boost the effectiveness of stem-cell transplants, commonly used for patients with cancer, blood disorders, or autoimmune diseases caused by defective stem cells, which produce all the body's different blood cells. The findings, made in mice, were published today in the journal Science.

Uncovering the Molecular Mechanisms Underlying Liver Regeneration

The liver can renew itself quite well. Maintaining organ function and recuperating from surgery or injury depends on this quality. Using clinical samples, researchers from the University of Leipzig Medical Center, the Max Planck Institute for Evolutionary Anthropology, TU Dresden, and ETH Zurich have examined the changes in liver cell types before and following regeneration.

Exploring the Use of Weakened Viruses for Cancer Treatment

Scientists at Northwestern Medicine have found that an attenuated virus can aid in the elimination of cancer in mice. Furthermore, mice given this virus treatment had a higher lifetime tumor-prevention rate.

Gene Therapy Can Interrupt the Progression of Deadly Inherited Heart Condition

A new study in mice shows that replacement of a dysfunctional gene could prolong survival in some people with arrhythmogenic right ventricular cardiomyopathy (ARVC), a rare inherited disorder in which the muscular walls of the heart progressively weaken and put patients at risk of dangerous irregular heartbeats.
