Cerebral Cortical Neuron Differentiation Service
Cerebral cortical neurons are the primary functional units of the mammalian cerebral cortex, responsible for cognition, memory, perception, motor control, language, and advanced neural circuit formation. Their dysfunction and loss are closely associated with many neurological and neuropsychiatric diseases, including Alzheimer's disease, autism spectrum disorder (ASD), schizophrenia, epilepsy, and cortical developmental disorders.
Key Features
- Derived from human iPSCs/ESCs under defined, xeno-free, and feeder-free conditions
- Uses dual SMAD inhibition for efficient dorsal cortical specification
- Generates layer-specific cortical neurons (deep layers: TBR1+; upper layers: CUX1+, BRN2+)
- High expression of cortical markers: PAX6, TBR2, MAP2, NeuN, VGLUT1
- Provides highly pure, electrophysiologically functional glutamatergic cortical neurons
Service Content
- Cortical neural progenitor induction and expansion
- Directed differentiation into mature cortical neurons
- Long-term maturation support for functional neural circuit formation
- Quality validation: immunofluorescence, qPCR, Western blot, calcium imaging
- Optional: patch‑clamp electrophysiology, 3D cortical organoids, co-culture systems

Case Study
Researchers generated and characterized cortical organoids and neurospheres from human iPSCs using a defined induction protocol. They differentiated iPSCs into cortical organoids, then dissociated and reaggregated them into uniform neurospheres. Immunostaining and flow cytometry were used to detect neural progenitor and cortical neuron markers.
At day 35, organoids formed rosette structures expressing FOXG1, SOX1, PAX6, and the deep-layer marker CTIP2. After reaggregation, flow cytometry confirmed abundant cortical progenitors and deep-layer neurons with no pluripotent cells remaining. Immunostaining verified the homogeneous structure of neurospheres.
These results show that the stepwise protocol efficiently drives iPSCs to differentiate into stable, homogeneous cerebral cortical neurons.

FAQs
Q: How do you ensure the neurons are functionally mature enough for electrophysiological studies?
A: We utilize Microelectrode Array (MEA) measurements and calcium imaging as standard QC steps. Our maturation protocols typically extend to 6 weeks or more, ensuring the presence of spontaneous firing and synaptic vesicle recycling, which are critical for meaningful data.
Q: Can we request specific genetic modifications, such as CRISPR-knockouts, in the neurons?
A: Yes, we offer all-side gene-editing services on the parent iPSC lines before differentiation. This allows you to study the impact of specific mutations on cortical development and disease progression in a controlled manner.
Q: How does your service compare to purchasing frozen primary neurons from other suppliers?
A: Unlike primary animal neurons, our iPSC-derived neurons are of human origin, eliminating species-specific metabolic differences. Furthermore, our customized differentiation ensures you receive specific cortical subtypes rather than a mixed neural population.
Q: What is the purity of the final neuronal population?
A: Through our optimized SFEBq and induction protocols, we routinely achieve over 90% purity for neural markers like PAX6 and TUJ1, with high specificity for cortical markers like CTIP2 and SATB2, minimizing background noise in your assays.
Q: Do you offer co-culture options with non-neuronal cells?
A: Absolutely. We can incorporate astrocytes, microglia, or pericytes into the differentiation workflow to create "niche-relevant" models that better simulate the cellular interactions and inflammatory environment of the human brain.
Creative Biolabs offers a world-class platform for the generation of human iPSC-derived cortical neurons, providing the precision, scalability, and functional validation required for modern drug discovery and regenerative medicine.
