Engineering a Perfusion Bioreactor System for hiPSC‐Derived Progenitor Co‐Culture Capturing Microglial Features in CNS Development

open access: yesBiotechnology and Bioengineering, EarlyView.
The authors report the development of a controlled and scalable 3D co‐culture system combining hiPSC‐derived erythromyeloid progenitors and neurospheres within the Ambr® 250 Modular platform operated with a newly designed perfusion system. This model faithfully recapitulates early microglia–neural interactions, enabling progenitor integration ...
