Innovative Therapeutic Strategies for Myocardial Infarction Across Various Stages: Non-Coding RNA and Stem Cells

Area of Science:

• Cardiovascular Research
• Regenerative Medicine
• Molecular Biology

Background:

• Myocardial infarction (MI) presents complex challenges throughout its progression.
• Non-coding RNAs (ncRNAs) and stem cells offer promising therapeutic avenues for MI.
• Current understanding of ncRNAs, stem cells, and exosomes in MI stages is limited.

Purpose of the Study:

• To systematically review the roles of ncRNAs, stem cells, and exosomes in different stages of MI.
• To elucidate the mechanisms by which these therapies promote cardiac repair and regeneration.
• To provide insights for novel therapeutic strategies and future research directions in MI treatment.

Main Methods:

• Systematic categorization of MI stages.
• Review of literature on ncRNA regulation in infarcted myocardium.
• Exploration of stem cell and exosome therapy mechanisms in MI progression.

Main Results:

• ncRNAs (miRNAs, LncRNAs) directly regulate intracellular pathways, angiogenesis, and repair in infarcted myocardium.
• Stem cells (MSCs, iPSCs) combined with ncRNAs enhance directed differentiation and cardiac cell replenishment.
• Stem cell-derived exosomes exert therapeutic effects via paracrine mechanisms, improving myocardial damage.

Conclusions:

• ncRNAs, stem cells, and exosomes show significant potential for treating MI across its pathological evolution.
• Targeting specific ncRNA and stem cell-based therapies at different MI stages can optimize treatment outcomes.
• Further research is needed to fully understand and harness these therapies for effective MI repair.
