Tokyo, Japan – Targeting drugs to cancer tissues is a major challenge in cancer treatment. Mesenchymal stem cells (MSCs) are known for their ability to find and target tumor cells in the body, but using MSCs for drug delivery has been tricky, because upon loading with drugs, MSCs lose their viability and migratory ability. Now, researchers from Tokyo University of Science have successfully modified MSCs to deliver large quantities of anti-cancer drugs in a targeted manner to developing cancer cells.
Exeter, UK – A team of scientists from the University of Exeter’s flagship Living Systems Institute has shown that stem cells contain no cancer mutations when they are grown in their most primitive or naïve state.
Dallas, TX, USA – A team led by UT Southwestern has derived a new “intermediate” embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm and eggs in a culture dish.
Bonn, Germany – Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues for drug testing and cell replacement therapies. However, the "recipes" for this conversion are often complicated and difficult to implement. Researchers at the Center for Regenerative Therapies Dresden (CRTD) at TU Dresden, Harvard University (USA) and the University of Bonn have found a way to systematically extract hundreds of different cells quickly and easily from iPS using transcription factors, including neurons, connective tissue and blood vessel cells. Researchers can use this transcription factor source through the non-profit organization Addgene. The results have now been published in the journal Nature Biotechnology
London, UK – Telomeres are specialised structures at the end of chromosomes which protect our DNA and ensure healthy division of cells. According to a new study from researchers at the Francis Crick Institute published in Nature, the mechanisms of telomere protection are surprisingly unique in stem cells.
San Diego, CA, USA – Scientists at Sanford Burnham Prebys Medical Discovery Institute have created a drug that can lure stem cells to damaged tissue and improve treatment efficacy- a scientific first and a major advance for the field of regenerative medicine. The discovery, published in the Proceedings of the National Academy of Sciences (PNAS), could improve current stem cell therapies designed to treat neurological disorders such as spinal cord injury, stroke, amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders; and expand their use to new conditions, such as heart disease or arthritis.
Cambridge, MA, USA – Periodontal disease, also known as gum disease, is a serious infection that affects nearly 50 percent of Americans aged 30 years and older. If left unchecked, periodontal disease can destroy the jawbone and lead to tooth loss. The disease is also associated with higher risk of diabetes and cardiovascular disease.
Montréal, Canada – In a world first, a young man suffering from severe aplastic anemia who could not be helped by standard treatments has been given a life-saving blood transplant with the made-in-Canada UM171 molecule.
Birmingham, AL, USA – Science has long known that recovery from experimental heart attacks is improved by injection of a mixture of heart muscle cells, endothelial cells and smooth muscle cells, yet results have been limited by poor engraftment and retention, and researchers worry about potential tumorigenesis and heart arrhythmia.
