What Are Muse Cells?
Definition
Muse cells (Multilineage Differentiating Stress Enduring cells) are a unique type of naturally occurring stem cell that combines the best qualities of several cell types while avoiding many of their limitations.
Location
They exist naturally in our bodies, primarily in connective tissues and bone marrow.
Identification
Muse cells can be identified by a specific marker called SSEA-3 (stage-specific embryonic antigen-3) and are also positive for typical mesenchymal markers like CD105.
Muse Cells vs. Other Stem Cells
The Stress-Enduring Nature of Muse Cells
1
Stress Exposure
Muse cells encounter harsh conditions that damage other cells
2
Survival Mechanisms Activate
Production of serine protease inhibitors (serpins) and 14-3-3 proteins
3
Protection and Survival
These proteins act as cellular bodyguards, preventing premature cell death
4
Enhanced Therapeutic Potential
Stress tolerance allows Muse cells to function in damaged tissues
Immune Privilege of Muse Cells
HLA-G Expression
Muse cells express high levels of human leukocyte antigen-G (HLA-G)
Natural Protection
HLA-G is the same molecule that prevents a mother's immune system from rejecting a developing fetus
Transplantation Advantage
Allows Muse cells to be transplanted between different individuals without requiring aggressive immunosuppression
Clinical Benefit
Simplifies treatment processes and reduces risks associated with immunosuppression
Homing Ability of Muse Cells
1
Tissue Damage
Injured tissue releases sphingosine-1-phosphate (S1P) as a distress signal
2
Signal Detection

When attached to surfaces in the body, Muse cells maintain a stable, quiescent state
Transition
Upon detachment and entering circulation, Muse cells undergo remarkable changes
Suspended State
Pluripotency-related genes become more active, enhancing regenerative capabilities
