Further research will focus on
generating skeletal muscle stem cells that can respond to continuous injury and regenerate new muscle long - term using the team's new isolation and maturation strategy.
Using mouse
skeletal muscle stem cells as a model, we show that accumulating transcripts specifying the myogenic program are not translated in quiescent satellite cells, but are repressed by the action of microRNAs and RNA binding proteins.
One of the molecular mysteries hindering development of regenerative therapy for muscles is uncovering the precise genetic and molecular processes that
cause skeletal muscle stem cells (called myoblasts) to fuse and form the striated muscle fibers that allow movement.
For years, scientists have been trying different methods that direct human pluripotent stem cells to
generate skeletal muscle stem cells that can function appropriately in living muscle and regenerate dystrophin - producing muscle fibers.

of skeletal muscle stem cells: functional evidence of their potential for cardiac differentiation?»
But when even low doses of doxycycline were given to the recipients to turn on DUX4 in
the skeletal muscle stem cells, muscle regeneration was severely impaired.
Manipulation of these genes in the mouse gives new insight into their role in the specification, proliferation and survival of
skeletal muscle stem cells.
