Summary
We developed a simple protocol to generate microglia-like cells from human induced pluripotent stem cells (hiPSCs). This method uses SPI1 and CEBPA overexpression for efficient differentiation, aiding neurological disorder modeling and drug discovery.
Area of Science:
- Stem cell biology
- Neuroscience
- Cellular reprogramming
Background:
- Modeling neurological disorders requires specific cell types like microglia.
- Human induced pluripotent stem cells (hiPSCs) offer a renewable source for cell generation.
- Efficient differentiation protocols are needed for disease modeling and drug screening.
Purpose of the Study:
- To establish a robust and efficient protocol for differentiating hiPSCs into microglia-like cells (iMGs).
- To enable better modeling of neurological disorders and facilitate drug screening and toxicity testing.
Main Methods:
- Overexpression of SPI1 and CEBPA transcription factors.
- Stepwise protocol involving hiPSC culture, lentivirus production, and delivery.
- Differentiation and validation of the generated microglia-like cells.
Main Results:
- Successfully generated a homogeneous population of microglia-like cells (iMGs) from hiPSCs.
- Demonstrated a simple, robust, and efficient differentiation process.
- Validated the identity and function of the iMGs.
Conclusions:
- The developed protocol provides a reliable method for generating iMGs from hiPSCs.
- This advancement supports research in neurological diseases, drug screening, and toxicity testing.
- Efficient iMG generation is critical for in vitro disease modeling.

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...
