Oral Mesenchymal Stem/Progenitor Cells: The Immunomodulatory Masters

Area of Science:

• Regenerative Medicine
• Immunology
• Oral Biology

Background:

• Oral mesenchymal stem/progenitor cells (MSCs) are valuable for tissue engineering due to their differentiation capacity and accessibility.
• These cells, including PDLSCs, DPSCs, SHED, GMSCs, SCAP, DFSCs, BM-MSCs, and hPCy-MSCs, are found in various oral tissues.
• Oral MSCs can interact with inflammatory environments and exert significant immunomodulatory effects.

Purpose of the Study:

• To review the immunomodulatory roles of oral MSCs in periodontitis and systemic diseases.
• To discuss the "double-edged sword" nature of oral MSCs in regulating inflammation.
• To elucidate the mechanisms underlying these effects, including the involvement of MSC-derived extracellular vesicles.

Main Methods:

• Literature review of current research on oral MSCs and their immunomodulatory functions.
• Analysis of studies investigating the interaction between oral MSCs and inflammatory conditions.
• Examination of mechanisms involving oral MSC-derived extracellular vesicles.

Main Results:

• Oral MSCs possess significant immunomodulatory capabilities, influencing both local and systemic inflammation.
• Their effects on the immune system can be context-dependent, presenting a "double-edged sword" characteristic.
• Extracellular vesicles secreted by oral MSCs play a crucial role in mediating their immunomodulatory actions.

Conclusions:

• Oral MSCs are key players in modulating immune responses within inflammatory conditions like periodontitis.
• Understanding their complex immunomodulatory functions is vital for developing novel therapeutic strategies.
• Targeting oral MSCs and their secreted vesicles offers promising avenues for treating inflammatory and regenerative diseases.
