Myogenic differentiation of human mesenchymal stromal cells
In the cell-based tissue engineering of muscle tissues, autologous smooth muscle cells are often used as a cell source. However, such cells are often unavailable, as they cannot be generated from diseased organs or those with malignancies. Moreover, the removal of muscle tissue for generating autologous smooth muscle cells creates another muscle defect and can result in high morbidity.
The use of mesenchymal stromal cells (MSCs) differentiated towards a smooth muscle cell phenotype may provide a promising alternative. Melanie and her team developed a xenogenic-free protocol for differentiating MSCs into contractile smooth muscle cells within 1-2 weeks that could be made available for in vitro / in vivo studies. Current aims include the development of a novel and clinically applicable approach for driving adult progenitor cells into skeletal muscle for regeneration in traumatized or degenerating tissues.
