Macrophage manufacturing: Protecting function through harvest
Macrophages serve two main roles in industry: as an in vitro test system for detecting pyrogens and as a therapeutic. While their applications differ, their manufacturing depends on the same three requirements: scale adherent surface area without a switch to suspension, put harvest quality and functional integrity ahead of expansion yield, and detach cells gently.
This white paper covers:
- How adherent growth, post-mitotic biology and harvest sensitivity set platform requirements
- Why harvest is closer to a functional test than a transfer step
- How manufacturing variability played out in MATCH01, a phase 2 macrophage therapy trial
- Functional data from large-scale adherent culture, at two vessel scales
- Monocyte-derived and iPSC-derived macrophages compared
- A five-question framework for testing a platform decision early
