  • New link between diet, intestinal stem cells and disease discovered November 19, 2021
    Obesity, diabetes and gastrointestinal cancer are frequently linked to an unhealthy diet. However, the molecular mechanisms responsible for this are not fully understood. Researchers have gained some new insights that help to better understand this connection. These findings provide an important basis for the development of non-invasive therapies.
  • A stunning 3D map of blood vessels and cells in a mouse skull could help scientists make new bones November 19, 2021
    Scientists have used glowing chemicals and other techniques to create a 3D map of the blood vessels and self-renewing 'stem' cells that line and penetrate a mouse skull. The map provides precise locations of blood vessels and stem cells that scientists could eventually use to repair wounds and generate new bone and tissue in the […]
  • Toward 'off-the-shelf’ immune cell therapy for cancer November 16, 2021
    Immunotherapies, which harness the body's natural defenses to combat disease, have revolutionized the treatment of aggressive and deadly cancers. But often, these therapies -- especially those based on immune cells -- must be tailored to the individual patient, costing valuable time and pushing their price into the hundreds of thousands of dollars.
  • For stem cells, bigger doesn’t mean better November 13, 2021
    A new study suggests that enlargement of stem cells contributes to age-related decline in function. The researchers found that blood stem cells, which are among the smallest cells in the body, lose their ability to perform their normal function -- replenishing the body's blood cells -- as they grow larger. When the cells were restored […]
  • New technique may lead to safer stem cell transplants November 11, 2021
    Studying mice, researchers have developed a method of stem cell transplantation that does not require radiation or chemotherapy. Instead, the strategy takes an immunotherapeutic approach, combining the targeted elimination of blood-forming stem cells in the bone marrow with immune-modulating drugs to prevent the immune system from rejecting the new donor stem cells.
  • Stem cells do not (only) play dice November 8, 2021
    In just a few weeks a completely new organism develops from a fertilized egg cell. The real miracle is that a bunch of identical stem cells turns into completely different, specialized cell types. A team has now been able to show that the specialization of individual cells during embryonic development is not, as previously assumed, […]
  • Researchers identify core genetic networks driving human embryonic stem cell behavior October 28, 2021
    Researchers uncovered key networks that simultaneously control pluripotency and readiness for cell death (apoptosis), helping to ensure optimal conditions for embryonic development. The study's findings offer new insights into cancer genetics and a novel approach for regenerative medicine research.
  • Protein involved in heart development boosts stem cell strategy for heart repair, scientists show October 21, 2021
    With age, the human heart gradually loses its ability to repair itself following injury. Damage wrought by injuries such as cardiac ischemia and heart attack, which are associated with decreased oxygen levels in the heart, can cause the heart to function below normal capacity, making it difficult for patients to carry out day-to-day activities. To […]
  • Scientists develop sperm cells from primate stem cells October 20, 2021
    A new study shows that functional sperm cells can be made in a dish using primate embryonic stem cells.
  • Developing a treatment for vision loss through transplant of photoreceptor precursors October 18, 2021
    A recent study examining the therapeutic potential of photoreceptor precursors, derived from clinically compliant induced pluripotent stem cells (iPSC), has demonstrated the safety and therapeutic potential of clinically compliant iPSC-derived photoreceptor precursors as a cell replacement source for future clinical trials.
