Such methods find particular use in the treatment of patients post-myocardial infarction to prevent or limit scarring and to promote myocardial repair.

Loss of cardiomyocytes underlies most causes of heart failure, and normal repair processes are inadequate to deal with extensive myocardial damage. The inventors have identified mutations of the N-terminus of serum respose factor (SRF)'s MADS box, termed STEMINs, that block cardiac differentiation, but also powerfully activate the stem cell marker genes Nanog and Octomer 4, as well as cyclins, which promotes adult myocyte replication. SRF Stemin mutations are not cardiac-specific, and also propel mammalian fibroblasts into a proliferative state. Thus, STEMINs may be useful for regeneration of all tissue and organ types, by activating partial pluripotency programs and enhancing repair by increased cell replication. Following withdrawal of STEMINs, the cells then return to normal cell identity.
