High-Throughput On-Chip Human Mesenchymal Stromal Cell Potency Prediction.

Area of Science:

• Biomedical Engineering
• Cell Therapy
• Regenerative Medicine

Background:

• Human mesenchymal stromal cells (hMSCs) show promise for regenerative therapies.
• Clinical application is hindered by donor variability and inconsistent outcomes.
• Predicting hMSC potency is crucial for market success but current assays lack scalability and translational power.

Purpose of the Study:

• To develop a high-throughput, scalable, and cost-effective on-chip microfluidic potency assay for hMSCs.
• To improve the functional predictive power of hMSC potency assessment.
• To better recapitulate in vivo secretory responses compared to traditional methods.

Main Methods:

• Development of an on-chip microfluidic system for hMSC potency assessment.
• Comparison of hMSC secretory responses in the microfluidic system versus traditional methods.
• Evaluation of on-chip microfluidic markers against functional immune cell suppression and in vivo models.

Main Results:

• The microfluidic assay demonstrates improved functional predictive power for hMSC potency.
• On-chip markers show better correlation with immune cell suppression than traditional markers.
• hMSC secretory performance in the microfluidic system more closely resembles in vivo conditions.

Conclusions:

• Current hMSC culture and potency assessment methods have significant limitations.
• The novel microfluidic system offers enhanced functional predictive power and physiological relevance.
• This technology could advance the clinical translation of hMSC-based therapies.
