As a type of cell with self-renewal ability and multi-directional differentiation potential, stem cells are closely related to their functions, such as reprogramming transcription factors, histone modifications, and energy metabolism. m6A (N6-methyladenosine modification) is one of the most abundant modifications in RNA, and dynamic reversible m6A modification plays an important role in regulating stem cell function. This review moves beyond listing isolated functions and instead adopts an integrated perspective, viewing m6A as a temporal regulator of cellular state transitions. We discuss how m6A dynamically regulates stem cell pluripotency, coordinates epigenetic and metabolic reprogramming, and serves as a central hub integrating key signaling pathways (Wnt, PI3K-AKT, JAK-STAT, and Hippo). Finally, using somatic reprogramming as an example, we elucidate the stage-specific role of m6A in complex fate transitions. This comprehensive exposition not only clarifies the context-dependent logic of m6A regulation but also provides a precise framework for targeting the m6A axis in regenerative medicine and cancer therapy.
