Abstract

Cerebral organoids are 3D stem cell-derived models that can be utilized to study the human brain. The current consensus is that cerebral organoids consist of cells derived from the neuroectodermal lineage. This limits their value and applicability, as mesodermal-derived microglia are important players in neural development and disease. Remarkably, here we show that microglia can innately develop within a cerebral organoid model and display their characteristic ramified morphology. The transcriptome and response to inflammatory stimulation of these organoid-grown microglia closely mimic the transcriptome and response of adult microglia acutely isolated from post mortem human brain tissue. In addition, organoid-grown microglia mediate phagocytosis and synaptic material is detected inside them. In all, our study characterizes a microglia-containing organoid model that represents a valuable tool for studying the interplay between microglia, macroglia, and neurons in human brain development and disease.

Funding

We are grateful to the Netherlands Brain Bank (http://www.brainbank.nl) who provided us with the post mortem human brain tissue. We thank the MIND facility at the UMC Utrecht for their help. We are thankful to M.H.M. de Goeij for setting up the phagocytosis assay and Dr. R. F. Hevner (University of Washington, Seattle, WA) for providing us with the TBR1 antibody. Furthermore, we want to thank Vanessa Marques Donega for providing us with adult MG for an experiment and Yujie He for helping with ELISA assays. Lastly, we are grateful for the advice on bioinformatics from Mark K. Bakker and Onur Basak.
