iPSC-derived Microglia Generation Service
Microglia are the resident immune cells of the central nervous system (CNS). They play crucial roles in immune surveillance, responding to injury and pathogens, synaptic pruning, and neuronal support and protection. Dysfunctional microglial responses have been implicated in many neurological and neurodegenerative diseases.
Microglia can be derived from induced pluripotent stem cells (iPSCs) through specific differentiation protocols. iPSCs are stem cells reprogrammed from somatic cells like skin or blood cells back into a pluripotent state. The iPSCs can then be directed to become microglial progenitor cells that mature into functional microglia-like cells. Creative Biolabs offers custom services to generate iPSC-derived microglia for research applications.

Common Assays Utilize iPSC-derived Microglia
- Phagocytosis and oxidative stress functional assays
Assessing microglial phagocytic activity and production of reactive oxygen species which can damage neurons.
- Co-cultures with iPSC-derived neurons/astrocytes
Modeling interactions between microglia and other neural cell types by co-culturing in 2D/3D systems.
- Inflammatory response/cytokine profiling assays
Quantifying secretion of pro-inflammatory cytokines like TNF-α, and IL-1β in response to immune challenges.
- Compound screening for anti-inflammatory/neuroprotective effects
High-throughput screens to identify compounds that modulate microglial activation and improve neuronal survival.
- RNA-sequencing and microglial signature analysis
Transcriptomic profiling to define gene expression patterns associated with different microglial activation states.
Microglial Dysfunction Has Been Linked To
- Alzheimer's disease: Microglia implicated in amyloid-beta clearance
Microglia normally clear amyloid-beta plaques, but this function becomes impaired in Alzheimer's, exacerbating the disease.
- Parkinson's disease: Neuroinflammation and oxidative stress
Overactive microglia induces oxidative stress and neuroinflammation that damages dopaminergic neurons in Parkinson's.
- Multiple sclerosis: Microglial activation and CNS inflammation
In MS, aberrant microglial activation contributes to damaging CNS inflammation and demyelination of neurons.
- Stroke: Microglia mediate post-ischemic neuroinflammation
After ischemic stroke injury, microglia become over-activated, causing oxidative damage and impairing neuronal recovery.
- Autism spectrum disorders: Altered synaptic pruning
Microglia regulate synaptic pruning during development, and impairments may contribute to autism phenotypes.
iPSC models allow studying patient microglia harboring disease-relevant genetic backgrounds. Researchers can investigate aberrant microglial responses, evaluate new therapeutics targeting microglia, and explore cell therapy approaches using iPSC-derived microglia.
In summary, iPSC-derived microglia serve as a powerful platform for studying microglial biology, and neuroinflammation and developing new therapies for various neurological conditions involving microglial dysfunction. Creative Biolabs provides iPSC-derived microglia designed to meet the specific requirements of your project's research needs. Let us guide you through your experimental investigations and help advance your understanding of neuroinflammation.
