Partial pluripotent reprogramming in C2C12 myoblasts


ABSTRACT: Partial pluripotent reprogramming has been reported to reverse some features of aging in mammalian cells and tissues. However, the impact of partial reprogramming on somatic cell identity programs and the necessity of individual pluripotency factors remain unknown. Here, we mapped trajectories of partial reprogramming in young and aged cells from multiple murine cell types using single cell transcriptomics to address these questions. We found that partial reprogramming restored youthful gene expression in adipogenic cells and mesenchymal stem cells but also temporarily suppressed somatic cell identity programs. We further screened Yamanaka Factor subsets and found that many combinations had an impact on aging gene expression and suppressed somatic identity, but that these effects were not tightly entangled. We also found that a partial reprogramming approach inspired by amphibian regeneration restored youthful gene expression in aged myogenic cells. Our results suggest that partial pluripotent reprogramming poses a neoplastic risk, but that restoration of youthful gene expression can be achieved with alternative strategies.
