New perspective into mesenchymal stem cells: Molecular mechanisms regulating osteosarcoma

Area of Science:

• Oncology
• Stem Cell Biology
• Regenerative Medicine

Background:

• Mesenchymal stem cells (MSCs) are multipotent cells with significant regenerative potential.
• Osteosarcoma tumorigenesis involves complex interactions within the tumor microenvironment (TME).
• MSCs play an integral role in the TME, influencing cancer progression.

Purpose of the Study:

• To elucidate the role of MSCs in osteosarcoma development and cellular communication within the TME.
• To review the therapeutic potential of modified MSCs for targeted osteosarcoma treatment.
• To discuss the clinical prospects of MSC-based therapies for osteosarcoma.

Main Methods:

• Review of existing literature on MSCs, osteosarcoma, and the TME.
• Analysis of MSC-mediated cellular communication via extracellular vesicles.
• Exploration of MSC modification strategies for drug delivery and gene therapy.

Main Results:

• MSCs interact with TME components through autocrine and paracrine signaling.
• Extracellular vesicles mediate intercellular communication between MSCs and other TME cells.
• MSCs can be engineered as biological carriers for targeted osteosarcoma treatment.

Conclusions:

• MSCs significantly influence osteosarcoma progression and the TME.
• Targeted modification of MSCs offers promising avenues for osteosarcoma therapy.
• Further research into MSC-TME interactions could unlock novel clinical applications.
