The present disclosure provides methods of generating skeletal muscle progenitor cells (SMPCs). The present disclosure provides methods of generating immature SMPCs and multinucleated muscle cells, and matured SMPCs and multinucleated muscle cells. The present disclosure provides engraftment methods and treatment methods, involving generating SMPCs and introducing the SMPCs into an individual.

Methods for generating skeletal muscle progenitor cells

In various embodiments a polyrotaxane carrier for in vivo delivery of a nucleic acid is provided. In certain embodiments the carrier comprises: a multi-arm polyethylene glycol (PEG) backbone comprising at least three arms; at least one cyclic compound having a cavity, where an arm of said multi-arm PEG backbone is threaded into the cavity of said cyclic compound forming an inclusion complex; a bulky moiety capping the terminal of the arm(s) threaded into said cyclic compound where said moiety inhibits dethreading of the cyclodextrin from the arm(s) of said backbone; and where at least one arm of said PEG backbone is free of cyclic compounds; and where said carrier has a net positive charge.
