  • Hidden messages in protein blueprints March 30, 2020
    Scientists have identified a new control mechanism that enables stem cells to adapt their activity in emergency situations. For this purpose, the stem cells simultaneously modify the blueprints for hundreds of proteins encoded in the gene transcripts. In this way, they control the amount of protein produced and can also control the formation of certain […]
  • Stem cells and nerves interact in tissue regeneration and cancer progression March 23, 2020
    Researchers show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumor innervation could thus lead to new cancer therapies.
  • Immunotherapy using 'young cells' offers promising option against cancer March 23, 2020
    A new study suggests that the age of certain immune cells used in immunotherapy plays a role in how effective it is. These cells -- natural killer (NK) cells -- appear to be more effective the earlier they are in development, opening the door to the possibility of an immunotherapy that would not utilize cells […]
  • How skin cells prepare to heal wounds March 19, 2020
    Researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds. Results from the study provide a blueprint for future investigation into pathological conditions associated with poor wound healing, such as in diabetic patients.
  • New technique 'prints' cells to create diverse biological environments March 18, 2020
    With the help of photolithography and programmable DNA, researchers have created a new technique that can rapidly 'print' two-dimensional arrays of cells and proteins that mimic a wide variety of cellular environments in the body. This technique could help scientists develop a better understanding of the complex cell-to-cell messaging that dictates a cell's final fate.
  • Solving the riddle of superbug toxin damage to gut March 16, 2020
    Scientists have revealed that a bacterial superbug can prevent stem cells in the gut from carrying out their vital role of regenerating the inner lining of the intestine.
  • Blood stem cells boost immunity by keeping a record of previous infections March 13, 2020
    Scientists have uncovered a surprising property of blood stem cells: not only do they ensure the continuous renewal of blood cells and contribute to the immune response triggered by an infection, but they can also remember previous infectious encounters to drive a more rapid and more efficient immune response in the future.
  • How stem cells repair damage from heart attacks March 13, 2020
    Researchers have uncovered stem cell-activated mechanisms of healing after a heart attack. Stem cells restored cardiac muscle back to its condition before the heart attack, in turn providing a blueprint of how stem cells may work.
  • New method to grow human blood vessels March 11, 2020
    A team of researchers recently proved the ability to grow human-derived blood vessels in a pig -- a novel approach that has the potential for providing unlimited human vessels for transplant purposes.
  • Second patient has been cured of HIV, study suggests March 10, 2020
    A study of the second HIV patient to undergo successful stem cell transplantation from donors with a HIV-resistant gene, finds that there was no active viral infection in the patient's blood 30 months after they stopped anti-retroviral therapy, according to a case report.
