MSCs can be a double-edged sword in tumorigenesis

Area of Science:

• Oncology
• Immunology
• Stem Cell Biology

Background:

• Mesenchymal stem cells (MSCs) are explored for treating diseases like Alzheimer's and cancer.
• The immunomodulatory function of MSCs is crucial for stem cell-based cancer therapy.
• MSCs exhibit both cancer-promoting and cancer-inhibiting effects.

Purpose of the Study:

• To review the application of MSCs in cancer immunotherapy.
• To elucidate the immunomodulatory mechanisms of MSCs within the tumor microenvironment (TME).
• To address the ambiguity in MSCs' effects on cancer, impacting therapeutic outcomes.

Main Methods:

• Literature review focusing on MSCs in cancer immunotherapy.
• Analysis of studies detailing MSCs' immunomodulatory functions in various cancers.
• Examination of the TME's influence on MSC behavior and anti-cancer activity.

Main Results:

• MSCs possess significant immunomodulatory capabilities within the TME.
• The dual role of MSCs (promotive vs. inhibitory) is linked to context-dependent TME interactions.
• Varied outcomes in MSC-based cancer therapies stem from these ambiguous immunomodulatory effects.

Conclusions:

• MSCs offer potential in cancer immunotherapy but require careful consideration of their TME interactions.
• Further research into MSC immunomodulation is essential for optimizing stem cell therapies for cancer.
• Clarifying MSCs' dual roles is critical for advancing their clinical application in oncology.
