  • Using barcodes to trace cell development August 16, 2017
    There are various concepts about how blood cells develop. However, they are based almost exclusively on experiments that solely reflect snapshots. Scientists now present a novel technique that captures the process in a dynamic way. Using a 'random generator,' the researchers label hematopoietic stem cells with genetic barcodes that enable them to trace which cell […]
  • Estrogen receptor stem cells found in mammary glands August 16, 2017
    One of the key questions in stem cell and cancer biology is to understand the cellular hierarchy governing tissue development and maintenance and the cancer cell of origin. Researchers have now identified a novel lineage - restricted stem cell in the mammary gland. In the future, this model will be used to assess whether the […]
  • How a nutrient, glutamine, can control gene programs in cells August 15, 2017
    Researchers show that an intracellular metabolite of glutamine, alpha-ketoglutarate, plays a role in regulating cellular differentiation programs by changing the DNA-binding patterns of the transcription factor CTCF and by altering genome interactions. As an added level of gene program control complexity, they have found that the genome's context near the binding sites -- such as […]
  • New way to activate stem cells to make hair grow August 14, 2017
    Researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss associated with such factors as hormonal imbalance, stress, aging or chemotherapy treatment.
  • Cardiac stem cells from young hearts could rejuvenate old hearts August 14, 2017
    Cardiac stem cell infusions could someday help reverse the aging process in the human heart, making older ones behave younger, according to a new study.
  • Aging is exacerbated by alterations of stem cell circadian rhythm August 10, 2017
    Two new studies refute the scientific dogma associating aging with the loss of stem cell circadian rhythm. The studies show that during aging, stem cells continue to show rhythmic activity but reprogram their circadian functions. The team also demonstrate that a low-calorie diet delays alterations in the rhythmic functions of stem cells and slows down […]
  • Test results after stem cell transplant for multiple myeloma can confuse patients and doctors about cancer's status August 10, 2017
    It's a cancer of the plasma cells, which normally make an array of antibodies that protect us from infection. With multiple myeloma, the cells start primarily producing instead a singular product, called a monoclonal antibody that leaves patients vulnerable for serious infections, like pneumonia, and can even eat away at their bones. Sophisticated lab tests […]
  • New insight into how immune cells are formed August 10, 2017
    In contrast to what has been previously believed, development of blood stem cells to mast cells, a type of specialised immune cell, does not depend on a growth factor called stem cell factor. The results could pave the way for new treatments for certain types of blood diseases.
  • Transforming skin cells to insulin August 9, 2017
    Researches are one step closer to cure diabetes by making insulin-producing cells from skin cells. They have transformed skin puncture cells from diabetes patients into insulin producing cells, using stem cell techniques. The researchers’ aim is to transplant these cells under the skin of people with diabetes.
  • New genes discovered regulating brain metastases in lung cancer patients August 8, 2017
    Researchers set out to find which genes can regulate the cells that initiate brain metastases, and outline their findings in a new report.
