Laser light can be used to create chemical channels that guide the regeneration of severed nerves.

The technique, devised by researcher Molly Shoichet and colleagues at the University of Toronto’s Institute for Biomaterials and Biomedical Engineering in Canada, helps guide cell migration and cell adhesion for applications such as tissue engineering.



Tissue engineering uses a combination of cells, engineering materials and biochemical factors to replace, repair or regenerate tissues.



Cell migration and cell adhesion are both very important factors for tissue engineering and regeneration.
