  • Mechanism by which exercise strengthens bones and immunity February 24, 2021
    Scientists have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the bone and immune-forming cells that it contains. Together, these findings identify a new way […]
  • Scientists repair injured spinal cord using patients' own stem cells February 22, 2021
    Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers report.
  • How a longevity gene protects brain stem cells from stress February 19, 2021
    A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study.
  • Researchers identify mechanisms that are essential for proper skin development February 18, 2021
    Latest discovery could improve development of future stem cell therapies and cancer treatments.
  • Early step toward leukemia drug therapy February 16, 2021
    The team has discovered that for acute myeloid leukemia (AML) patients, there is a dopamine receptor pathway that becomes abnormally activated in the cancer stem cells. This inspired the clinical investigation of a dopamine receptor-inhibiting drug thioridazine as a new therapy for patients, and their focus on adult AML has revealed encouraging results.
  • Unlocking the mystery behind skeletal aging February 16, 2021
    Researchers have identified the role a critical enzyme plays in skeletal aging and bone loss, putting them one step closer to understanding the complex biological mechanisms that lead to osteoporosis, the bone disease that afflicts some 200 million people worldwide. Findings could hold an important key to developing more effective treatments for osteoporosis and improving […]
  • Wake-up call for neural stem cells February 11, 2021
    A brain enzyme activates dormant neural stem cells, revealing how defects in its gene could lead to neurodevelopmental disorders.
  • Novel protein could reverse severe muscle wasting in disease, aging and trauma February 10, 2021
    Muscle stem cells drive the tissue's growth and repair after such injuries. But growing these cells in the lab and using them to therapeutically replace damaged muscle has been frustratingly difficult. Researchers have discovered a factor that triggers these muscle stem cells to proliferate and heal. In a mouse model of severe muscle damage, injections […]
  • A recipe for regenerating bioengineered hair February 10, 2021
    Scientists have recently developed ways to grow a variety of useful items in laboratories, from meat and diamonds to retinas and other organoids. A team has been working on ways to regenerate lost hair from stem cells. In an important step, a new study identifies a population of hair follicle stem cells in the skin […]
  • Hot nano-chisel used to create artificial bones in a Petri dish February 9, 2021
    Scientists detail a system allowing them to sculpt, in a biocompatible material, the exact structure of the bone tissue, with features smaller than the size of a single protein -- a billion times smaller than a meter.
