Potential new approach to regenerating skeletal muscle tissue

An innovative strategy for regenerating skeletal muscle tissue using cells derived from the amniotic fluid is outlined in new research published by scientists at the UCL Institute of Child Health. The paper shows that damaged muscle tissues can be treated with cells derived from the fluids which surround the fetus during development, leading to satisfactory regeneration and muscle activity. The treatment resulted in longer survival in mice affected by a muscle variant of spinal muscular atrophy. This is the first time that regeneration of diseased muscle tissue has been obtained using cells derived from amniotic fluid. The research appears in the journal Stem Cells , is authored by Paolo de Coppi (UCL Institute of Child Health and surgeon at Great Ormond Street Hospital) and colleagues in Paris and Padova, and represents an impressive development in the growing field of regenerative medicine. Muscle derived stem cells are presently considered the best source for muscle regeneration. However they cannot be used to treat muscular dystrophies because the stem cells themselves are affected in individuals with these conditions.
