  • Stem cells from hair follicles have potential to repair damaged neurons in mice April 24, 2019
    A subset of the stem cells in hair follicles have the potential to regenerate the coating that insulates neurons in mice, report scientists.
  • A new way to 'freeze' cells promises to transform the common cell-freezing practice April 24, 2019
    Researchers in Japan have demonstrated preserving frozen animal cells without a cryoprotectant agent, relying instead on ultrarapid cooling.
  • Welding with stem cells for next-generation surgical glues April 23, 2019
    Scientists have invented a new technology that could lead to the development of a new generation of smart surgical glues and dressings for chronic wounds. The new method involves re-engineering the membranes of stem cells to effectively 'weld' the cells together.
  • Factors behind embryonic stem cell state April 17, 2019
    An international collaboration has found for the first time that two new epigenetic regulators, TAF5L and TAF6L, maintain self-renewal of embryonic stem cells. The scientists also found that these proteins activate c-Myc (a well-known cancer gene), and its regulatory network. This is the first time scientists have been able to show what these regulators do […]
  • A light-activated remote control for cells April 17, 2019
    What if doctors had a remote control that they could use to steer a patient's own cells to a wound to speed up the healing process? Although such a device is still far from reality, researchers have taken an important first step: They used near-infrared light and an injected DNA nanodevice to guide stem cells […]
  • Boosting muscle stem cells to treat muscular dystrophy and aging muscles April 17, 2019
    Scientists have uncovered a molecular signaling pathway involving Stat3 and Fam3a proteins that regulates how muscle stem cells decide whether to self-renew or differentiate -- an insight that could lead to muscle-boosting therapeutics for muscular dystrophies or age-related muscle decline.
  • Scientists 'reverse engineer' brain cancer cells to find new targets for treatment April 16, 2019
    Glioblastoma is one of the most devastating forms of cancer, with few existing treatment options. It is also a leading cause of cancer-related death in children and young adults. Scientists have 'reverse engineered' brain cancer stem cells gene by gene, uncovering multiple potential targets for this hard-to-treat cancer.
  • How inflammation causes gastric cancer April 16, 2019
    Researchers have solved the decades-old mystery of how stomach bacterium Helicobacter pylori causes gastric cancer. Using mouse models and human cancer cell lines, they showed that inflammation resulting from bacterial infection leads to the proliferation of gastric epithelial cells, which ultimately form gastric tumors. By blocking the protein pathway responsible for this proliferation, they prevented […]
  • Discovery of 'kingpin' stem cell may help in the understanding of cancerous tumors April 11, 2019
    Bhatia's team spent more than six years delving down to the cellular level to examine what they say are previously overlooked cells that form on the edges of pluripotent stem cell colonies. Having characterized these cells, the team also observed them form at the earliest stages of pluripotent cell reprogramming from adult cells.
  • Shutting down deadly pediatric brain cancer at its earliest moments April 11, 2019
    Cell-by-cell genetic analyses of developing brain tissues in neonatal mice and laboratory models of brain cancer allowed scientists to discover a molecular driver of the highly aggressive, deadly, and treatment-resistant brain cancer, glioblastoma. The findings present an opportunity to find out if new therapeutic approaches can stop glioblastoma at its earliest stages of initial formation […]
