Washington, DC, USA – According to the U.S. Centers for Disease Control and Prevention, about half of all Americans will have periodontal disease at some point in their lives. Characterized by inflamed gums and bone loss around teeth, the condition can cause bad breath, toothache, tender gums and, in severe cases, tooth loss. Now, in ACS Nano, researchers report development of a membrane that helps periodontal tissue regenerate when implanted into the gums of rats.

Santa Cruz, CA, USA – A healthy adult makes about 2 million blood cells every second, and 99 percent of them are oxygen-carrying red blood cells. The other one percent are platelets and the various white blood cells of the immune system. How all the different kinds of mature blood cells are derived from the same "hematopoietic" stem cells in the bone marrow has been the subject of intense research, but most studies have focused on the one percent, the immune cells.
Atlanta, GA, USA – Scientists at Winship Cancer Institute of Emory University, Children's Healthcare of Atlanta and Georgia Tech have found that modulating blood-forming stem cells' stiffness could possibly facilitate mobilization procedures used for stem cell-based transplants.
New York, NY, USA – Increases in chronic inflammation – not the passage of time – is the main reason why injured bones do not heal as well with age. This is the finding of a study in mice and humans published online March 18, 2019 in the Proceedings of the National Academy of Sciences.
Berlin, Germany – Muscle stem cells have to be ready to spring into action at any time: When a muscle becomes injured, for example, during a sports activity, it is their responsibility to develop new muscle cells as quickly as possible. When a muscle grows, because its owner is still growing too or has started to do more sports, the conversion of stem cells is also required.
Winston-Salem, NC, USA – Wake Forest Institute for Regenerative Medicine (WFIRM) scientists are working on a promising approach for treatment of chronic kidney disease – regeneration of damaged tissues using therapeutic cells. By harnessing the unique properties of human amniotic fluid-derived stem cells, WFIRM scientists have demonstrated that the cells could potentially help recover organ function in a pre-clinical model of kidney disease.
Tel Aviv, Israel – All stem cells can multiply, proliferate and differentiate. Because of these qualities, leukemic stem cells are the most malignant of all leukemic cells. Understanding how leukemic stem cells are regulated has become an important area of cancer research. A team of Tel Aviv University (TAU) researchers have now devised a novel biosensor that can isolate and target leukemic stem cells. The research team, led by Dr. Michael Milyavsky of the Department of Pathology at TAU's Sackler School of Medicine, discuss their unique genetically encoded sensor and its ability to identify, isolate and characterize leukemic stem cells in a study published in Leukemia.
Osaka, Japan – The body needs to create a continuous supply of blood cells to enter circulation. Blood cells have a wide variety of functions ranging from supplying oxygen to tissues, fighting infections, and enabling the blood to clot upon injury. Avoiding deficiency of these cells or their excessive proliferation must involve a strict regulatory mechanism, but much remains to be clarified about how this works.
Utrecht, NL – Scientists from the Hubrecht Institute, Princess Máxima Center, Utrecht University and University Medical Center Utrecht have successfully created kidney organoids from urine cells. This could lead to a wide range of new treatments that are less onerous for kidney patients. The results of the research were published in Nature Biotechnology.
