A bone marrow transplant is often the only therapy available to save leukemia patients, but the risk of complications is high. In spite of devoting considerable time and effort to finding a suitable donor, nearly half of all patients experience an unwanted reaction of their immune system, which often attacks their skin and liver and in up to 50% of cases the intestines. Researchers at FAU (Friedrich-Alexander-Universität Erlangen-Nürnberg) have succeeded in deciphering what causes this in some instances life-threatening inflammation of the intestines, possibly opening up new approaches for treatment. They have published the results of their research in the Journal of Clinical Investigation.
The proper function of blood vessels is essential to life: blood vessels are responsible for transporting oxygen-rich red blood cells, nutrients, and immune cells throughout the body, to name just a few functions. Defects in blood vessels can correspondingly lead to a variety of life-threatening diseases. Stem cells, which are undifferentiated cells that can generate new tissues, have significant potential in regenerative medicine and treating various disorders. In blood vessels, the existence of tissue-resident stem cells has been intensely debated. A research team centered at Osaka University may now have discovered the elusive stem cell, providing evidence for adult vascular endothelial stem cells (VESCs) capable of generating fully functional blood vessels.
Scientists have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
New research from Sanford Burnham Prebys Medical Discovery Institute (SBP) is among the first to describe how an mRNA modification impacts the life of neural stem cells (NSCs). The study, published in Nature Neuroscience, reveals a novel gene regulatory system that may advance stem cell therapies and gene-targeting treatments for neurological diseases such as Alzheimer’s disease, Parkinson’s disease, and mental health disorders that affect cognitive abilities.
In a scientific first, researchers at the Gladstone Institutes turned skin cells from mice into stem cells by activating a specific gene in the cells using CRISPR technology. The innovative approach offers a potentially simpler technique to produce the valuable cell type and provides important insights into the cellular reprogramming process.
Tuberculosis (TB), an infectious disease which attacks the lungs, claims someone’s life every 20 seconds and 1.5 million lives worldwide every year. A cure has eluded scientists for more than a century but, now, a Montreal team of researchers may have discovered a new weapon to combat this global killer. The team is re-programing — or ‘training’ — immune cells to kill TB. These groundbreaking findings are published online today in the journal Cell.
Stem cells have been used therapeutically in horses for many years as a treatment option for tendon and joint injuries. These cells are commonly obtained surgically from bone marrow or fat tissue. Researchers have now for the first time managed to harvest stem cells from the mucous membrane of the equine uterus. By taking stem cells from the uterus without the need for surgical intervention, the procedure provides an alternative with reduced pain and stress for the animals.
A new method of harvesting stem cells for bone marrow transplantation may make the donation process more convenient and less unpleasant for donors while providing cells that are superior to those acquired by current protocols.
Engineers have developed a ‘heart patch’ that is just as strong and electrically active as healthy adult cardiac tissue and large enough to cover the damage caused by most heart attacks.
Scientists have developed a new system to study Creutzfeldt-Jakob disease in the laboratory, paving the way for research to find treatments for the fatal brain disorder.
