Abstract:
Wharton's jelly mesenchymal stem cells (WJ-SCs) are a promising source for regenerative medicine due to their multipotency, low immunogenicity, and ethical acceptability. Epigenetic regulation plays a crucial role in modulating their proliferation, differentiation, and therapeutic potential. Key mechanisms, including DNA methylation, histone modifications, and non-coding RNAs (e.g., miRNAs and lncRNAs), influence WJ-SC behavior by dynamically altering gene expression without changing the DNA sequence. DNA methylation often silences genes involved in differentiation, while histone acetylation/methylation can activate or repress lineage-specific pathways. Non-coding RNAs further fine-tune these processes by post-transcriptional regulation. Understanding these mechanisms could optimize WJ-SC-based therapies for tissue repair and immune modulation. This review summarizes current insights into epigenetic regulation in WJ-SCs and its implications for regenerative applications.
