  • Immune cell provides cradle for mammary stem cells May 17, 2018
    Researchers have made new discoveries about how an immune cell known as the macrophage, which normally fights infection by swallowing foreign invaders, nurtures mammary gland stem cells through a chemical signaling molecule. The study may provide important clues about the roles of macrophages in breast cancer progression.
  • Robots grow mini-organs from human stem cells May 17, 2018
    A robotic system has been developed to automate the production of human mini-organs derived from stem cells. The ability to rapidly, mass produce organoids promises to expand the use of mini-organs in basic research and drug discovery. The system was tested in producing kidney organoids, including models of polycystic kidney disease. The robots were also […]
  • Single surface protein boosts multiple oncogenic pathways in acute myeloid leukemia May 17, 2018
    Researchers have discovered that a signaling protein elevated in patients with acute myeloid leukemia (AML) plays a much wider role in the disease than previously thought. The study raises hopes that current efforts to target this signaling protein could be a successful strategy to treat AML and other blood cancers.
  • Researchers take key step toward growing human organs in laboratory May 16, 2018
    Researchers have learned that precursor cells for skeletal muscles actually also give rise to neurons, blood vessels, blood cells and immune cells, pushing science one step closer to generating body parts in a laboratory.
  • Elastic microspheres expand understanding of embryonic development and cancer cells May 14, 2018
    A new technique that uses tiny elastic balls filled with fluorescent nanoparticles aims to expand the understanding of the mechanical forces that exist between cells, researchers report. The team has demonstrated the quantification of 3D forces within cells living in petri-dishes as well as live specimens. This research may unlock some of the mysteries related […]
  • Tissue-engineered human pancreatic cells successfully treat diabetic mice May 8, 2018
    Researchers tissue-engineered human pancreatic islets in a laboratory that develop a circulatory system, secrete hormones like insulin and successfully treat sudden-onset type 1 diabetes in transplanted mice. The scientists use a new bioengineering process they developed called a self-condensation cell culture. The technology helps nudge medical science closer to one day growing human organ tissues […]
  • Molecule that supports blood-cell production under dietary stress is identified May 7, 2018
    Researchers report how the Spred1 molecule is involved in hematopoietic stem cell self-renewal. Experiments with mouse models show that under normal conditions, Spred1 acts as a negative regulator, while under diet-induced stress, it protects hematopoietic homeostasis.
  • Cancer cells thrive in stiff tissue May 4, 2018
    Scientists studying tumor growth and metastasis have fabricated a human tissue model to examine how cancer cells interact with connective tissue in the breast.
  • Gray hair linked to immune system activity and viral infection May 3, 2018
    A new study on mice offers insights into why some people's hair may turn gray in response to a serious illness or chronic stress. Researchers have discovered a connection between the genes that contribute to hair color and the genes that notify our bodies of a pathogenic infection.
  • Fasting boosts stem cells' regenerative capacity May 3, 2018
    Age-related declines in stem cell function can be reversed by a 24-hour fast, according to a new study. Biologists found fasting dramatically improves stem cells' ability to regenerate, in both aged and young mice.
