In vivo reprogramming for tissue regeneration and organismal rejuvenation

Abstract

Transcription factor-mediated reprogramming has enabled us to induce the fate conversion of somatic cells into other cell types. Although the study of reprogramming mostly occurs at the cellular level in vitro, previous studies have demonstrated that somatic cells are reprogrammable in multicellular organisms too. Recent studies using in vivo reprogramming have provided important insights on regenerative medicine for diseased organs. Moreover, similar studies have revealed unappreciated mechanisms in various biological phenomena, including tissue regeneration, aging, rejuvenation and cancer development in multicellular organisms. Here, we review recent progress and future perspectives of in vivo reprogramming.
