Abstract
Stem cell, bone and nerve scaffolding comprising discrete carbon nanotubes is disclosed. The discrete carbon nanotubes may be have targeted, or selective oxidation levels and/or content on the interior and exterior of the tube walls. The described scaffolding may be used to guide, target and protect stem cells upon injection into the body.
Claims28
A scaffold for transplanting a stem cell, which comprises discrete carbon nanotubes;
- wherein the scaffold does not exhibit cytotoxicity and wherein the discrete carbon nanotubes comprise an interior and exterior surface, the interior surface comprising an interior surface oxidized species content and the exterior surface comprising an exterior surface oxidized species content, and wherein the interior surface oxidized species content is less than the exterior surface oxidized species content.
A composition for stem cell therapy, which comprises:
- (a) at least one stem cell;
- and (b) discrete carbon nanotubes serving as a stem cell scaffold without cytotoxicity and wherein the discrete carbon nanotubes comprise an interior and exterior surface, the interior surface comprising an interior surface oxidized species content and the exterior surface comprising an exterior surface oxidized species content, and wherein the interior surface oxidized species content is less than the exterior surface oxidized species content.
A cell therapy method which comprises administering to an animal a composition for stem cell therapy comprising (a) at least one stem cell;
- and (b) discrete carbon nanotubes serving as a stem cell scaffold without cytotoxicity and wherein the discrete carbon nanotubes comprise an interior and exterior surface, the interior surface comprising an interior surface oxidized species content and the exterior surface comprising an exterior surface oxidized species content, and wherein the interior surface oxidized species content is less than the exterior surface oxidized species content.
