A team of European researchers has devised a strategy to ensure that adult epidermal stem cells are safe before they are used as treatments for patients. The approach involves a clonal strategy where stem cells are collected and cultivated, genetically modified and single cells isolated before being rigorously tested to make sure they meet the highest possible safety criteria. The strategy, which is published online in EMBO Molecular Medicine, is inspired by the approaches the biotechnology industry and regulatory affairs authorities have adopted for medicinal proteins produced from genetically engineered mammalian cells.
Bioengineers from Brigham and Women’s Hospital (BWH) with collaborators at the pharmaceutical company Sanofi have identified small molecules that can be used to program stem cells to home in on sites of damage, disease and inflammation. The techniques used to find and test these small molecules may represent important tools in advancing cell-based therapy, offering a new strategy for delivering cells to the right locations in the body. The results of their work appear online this week in Cell Reports.
Since the first experimental bone marrow transplant over 50 years ago, more than one million hematopoietic stem cell transplantations (HSCT) have been performed in 75 countries, according to new research charting the remarkable growth in the worldwide use of HSCT, published in The Lancet Haematology journal.
A new study led by researchers at The Scripps Research Institute (TSRI) and the University of California (UC), San Diego School of Medicine shows that certain stem cell culture methods are associated with increased DNA mutations. The study points researchers toward safer and more robust methods of growing stem cells to treat disease and injury.
Stem cells from the dental pulp of wisdom teeth can be coaxed to turn into cells of the eye’s cornea and could one day be used to repair corneal scarring due to infection or injury, according to researchers at the University of Pittsburgh School of Medicine. The findings, published online today in STEM CELLS Translational Medicine, indicate they also could become a new source of corneal transplant tissue made from the patient’s own cells.
Under normal conditions, many of the different types of tissue-specific adult stem cells, including hematopoietic stem cells, exist in a state or dormancy where they rarely divide and have very low energy demands. “Our theory was that this state of dormancy protected hematopoietic stem cells from DNA damage and therefore protects them from premature aging,” says Dr. Michael Milsom, leader of the study.
