The materials act as a sort of nanoscale three-dimensional scaffolding, to which lab-cultivated cells can be added, or that the recipient’s own cells can colonize. Now, a Spanish research team has used the same principle to grow new brain tissue – the technique could ultimately be used to treat victims of brain injuries or strokes. Link to Original Source

sole test of the validity of any idea is experiment."
