Musculoskeletal tissue regeneration occurs within the context of a three-dimensional microenvironment that relies upon dynamic interplay between biochemical and biophysical cues. The cellular and molecular impact of this interplay on muscle stem cell fate is not well understood. To gain a better understanding of the combinatorial inputs required to achieve tissue regeneration, we use two approaches: (1) engineered culture models to reconstruct parameters in vitro and (2) in vivo manipulation of individual parameters. These studies will inform future efforts aimed at developing engineered replacement musculoskeletal tissue for regenerative medicine applications.
