Development of a microdevice-based human mesenchymal stem cell-mediated drug delivery system

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Drug Delivery Systems

Background:

• Cell-mediated drug delivery leverages living cells as carriers for enhanced therapeutic outcomes.
• Human mesenchymal stem cells (hMSCs) are recognized for their therapeutic potential and use as carriers for nanoparticles.
• Existing systems often lack controlled integration and stability, necessitating innovative approaches.

Purpose of the Study:

• To develop and characterize a novel microdevice-based drug delivery system utilizing human mesenchymal stem cells (hMSCs).
• To evaluate the stability, viability, and functional characteristics of hMSC-microdevice complexes.
• To assess the potential of this system for future clinical translation in drug delivery.

Main Methods:

• Development of disk-shaped microdevices for integration with hMSCs.
• Formation and cultivation of hMSC-microdevice complexes.
• Assessment of complex stability, hMSC viability, proliferation, and functional assays (migration, spheroid formation, dissociation).

Main Results:

• Microdevices were controllably and versatily attached to hMSCs.
• The resulting hMSC-microdevice complexes demonstrated stability during cultivation and trypsinization.
• hMSC viability and proliferation were unaffected by microdevice attachment.
• hMSC-microdevice complexes retained key cellular functions, including migration and spheroid behavior.

Conclusions:

• The developed microdevice-based system offers a stable and functional platform for hMSC-mediated drug delivery.
• The system preserves critical hMSC characteristics, indicating its suitability for therapeutic applications.
• This innovative approach shows significant promise for advancement into a clinically viable drug delivery solution.
