Nanostimulators boost stem cells for muscle repair

May 1, 2020

In regenerative medicine, an ideal treatment for patients whose muscles are damaged from lack of oxygen would be to invigorate them with an injection of their own stem cells.

In a new study published in the journal ACS Nano, researchers at the University of Illinois at Urbana-Champaign demonstrated that “nanostimulators” – nanoparticles seeded with a molecule the body naturally produces to prompt stem cells to heal wounds – can amp up stem cells’ regenerative powers in a targeted limb in mice.

Injections, exercise promote muscle regrowth after atrophy in mice

By injecting cells that support blood vessel growth into muscles depleted by inactivity, researchers say they are able to help restore muscle mass lost as a result of immobility.

The research, conducted in adult mice, involved injections of cells called pericytes (PERRY-sites), which are known to promote blood vessel growth and dilation in tissues throughout the body. The injections occurred at the end of a two-week period during which the mice were prevented from contracting the muscles in one of their hind legs.
