Mesenchymal stem cells in the bone marrow appear to offer great possibilities in the regeneration or repair of damaged organs and tissues, particularly the heart. Recent research shows that single-walled carbon nanotubes in low concentration can be used as a delivery vehicle for the stem cells. They do not significantly affect cell life or proliferation -- and when the tubes move into the cell nucleus, they don't hurt the ultrastructure. "We hope to use the nanotubes as delivery vehicles for a range of different biomolecules for the manipulation of MSC differentiation pathways towards a range of different cell types," one of the researchers said.
