Overview

Short-term co-culture improves immune cell viability in colorectal tumor models, suggesting better tumor-immune interaction analysis.

Key Points

  • The study aims to optimize culture conditions for enhancing immune cell survival in tumoroid co-culture systems.
  • Utilized patient-derived tumoroids for co-culture with immune cells
  • Optimized OncoPro™ Tumoroid Culture Medium
  • Screened 13 cytokines and growth factors via a design of experiments (DOE) approach
  • Applied flow cytometry for cell population analysis
  • Compared embedded and suspension culture methods.
  • Supplemented medium with IL-2, IL-15, GM-CSF, and BAFF improved PBMC survival and immune composition
  • Suspension culture supported higher immune cell viability than embedded culture
  • Up to 80% PBMC loss in non-supplemented medium after 5 days
  • Cytokine-optimized medium enhanced total viable cell recovery and stability.
