Epitranscriptomic modifications in mesenchymal stem cell differentiation: advances, mechanistic insights, and beyond

Area of Science:

• Molecular Biology
• Stem Cell Biology
• Epigenetics

Background:

• RNA modifications, the epitranscriptome, are crucial for regulating biological processes in mesenchymal stem cells (MSCs).
• Enzymes like METTL, IGF2BP, WTAP, YTHD, FTO, and NAT catalyze these modifications, influencing MSC behavior.
• These modifications dynamically alter the MSC transcriptomic landscape, impacting differentiation, proliferation, and environmental responses.

Purpose of the Study:

• To provide a comprehensive overview of RNA modifications in MSCs.
• To elucidate the roles of RNA modifications in regulating stem cell behavior and their therapeutic implications.
• To discuss the interplay of modifications and their contribution to MSC functional diversity.

Main Methods:

• Literature review of current research on RNA modifications in MSCs.
• Analysis of the roles of specific RNA-modifying enzymes (writers, readers, erasers).
• Exploration of the impact of epitranscriptomic changes on MSC biology and potential therapeutic applications.

Main Results:

• RNA modifications significantly influence MSC differentiation, proliferation, and environmental responses.
• Specific RNA-modifying enzymes play key roles in MSC lineage development.
• The interplay of various RNA modifications contributes to the functional diversity of MSCs.

Conclusions:

• A deeper understanding of the epitranscriptome in MSCs is essential for advancing regenerative medicine.
• Harnessing RNA modification mechanisms holds promise for novel MSC-based therapeutic strategies.
• Further research requires innovative tools to map modifications and decipher their context-specific effects in MSCs.
