A new gel that could help grow the large quantities of neural stem cells needed for sought-after therapies has been developed by the researchers from Stanford University. Its success depends on the cells’ ability to stay in touch. On the one hand, these natural shapeshifters can transform themselves into virtually any type of cell in the body, they hold the promise of being able to cure ills ranging from spinal cord injuries to cancers (lat. Carcinoma). But on the other, stem cells are complicated to work with.
