Isolation and characterization of a Sca-1+/CD31- progenitor cell lineage derived from mouse heart tissue

摘要

BackgroundMyocardial infarction remains the leading cause of mortality in developed countries despite recent advances in its prevention and treatment. Regenerative therapies based on resident cardiac progenitor cells (CPCs) are a promising alternative to conventional treatments. However, CPCs resident in the heart are quite rare. It is unclear how these CPCs can be isolated and cultured efficiently and what the effects of long-term culture in vitro are on their ‘stemness’ and differentiation potential, but this is critical knowledge for CPCs’ clinical application.
