Regenerating Lost Cartilage

The key to coaxing cells to regenerate might be to make things a little rough for them. Thomas Webster, a bioengineer at Brown University, has been developing implantable materials with nanoscale textures to mimic the roughness of living tissues. Now, his team has found that cartilage cells can adhere to and grow more densely on a surface covered with carbon nanotubes, particularly when they are also exposed to electrical stimulation. Webster believes that surfaces incorporating carbon nanotubes, which are not only textured but are also electrically conductive, could be a promising strategy for designing cartilage implants
