Welding with stem cells for next-generation surgical glues

Scientists at the University of Bristol 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, pioneered by Dr Adam Perriman and colleagues, involves re-engineering the membranes of stem cells to effectively “weld” the cells together.

Scientists rejuvenate stem cells in the aging brain of mice

Scientists from the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg and from the German Cancer Research Center (DKFZ) have been able to rejuvenate stem cells in the brain of aging mice. The revitalised stem cells improve the regeneration of injured or diseased areas in the brain of old mice. The researchers expect that their approach will provide fresh impetus in regenerative medicine and facilitate the development of stem cell therapies.

Development of brain stem cells into new nerve cells and why this can lead to cancer

Stem cells are true Jacks-of-all-trades of our bodies, as they can turn into the many different cell types of all organs. This allows the tissues such as muscle or even brain to renew and to heal after injury. This amazing multipotency makes stem cells in the adult body key tools for the future of regenerative medicine. Scientists at the German Cancer Research Center (DKFZ) now publish in the journal Nature how brain stem cells make the decision to transform into new nerve cells.

Two-step control mechanism identified in mouse stem cells

Scientists identified two distinct control mechanisms in the developmental transition of undifferentiated stem cells into healthy brain cells. This fundamental research using mice may inform regenerative medicine treatments for neurodegenerative diseases and spinal cord injuries, in the future.
