axoCellsTM Cortical Inhibitory Interneurons


Build high-quality neurodegenerative disease models in 20 days. 

Ensure confidence in your workflow with high-quality axoCellsTM cortical inhibitory interneurons, differentiated from human induced pluripotent stem cells (iPSCs). Derived from two different consenting donors (newborn male and 40-50yr old male), our inhibitory interneurons have been specifically developed for use in mono-, co- and tri-culture models to investigate neurodegenerative diseases and for drug discovery.  

Our robust, physiologically relevant neurons have been shown to express the key cell markers (parvalbumin, somatostatin, tyrosine hydroxylase, PAX-6, MAP2, beta-tubulin, GABA receptor, and GAD enzyme). And with a maturity time of just twenty days, you can build robust models in less time. 

Early Access Offer package

Our inhibitory interneurons are available through our Early Access Program where we are offering the following options: 

  1. When you purchase a co-culture or tri-culture kit, you will receive 1 x a0662 and 1 x ax0667 interneurons free of charge. 
  2. If you wish to buy interneurons on their own, you can request a 50% discount on the purchase of a twin pack of 1 x ax0662 and 1 x ax0667.

Product Highlights

  • Robust, relevant interneurons express eight key markers including parvalbumin, PAX-6 and MAP2 
  • Produce mature cells in just 20 days, with functional calcium responses in 30 days  
  • Specifically designed for use in mono-, co- and tri-culture models to investigate neurodegenerative disorders and for drug discovery 
  • Used by leading Biopharma and academic institutions around the world to fuel robust mono, co- and tri-culture models  


Our axoCellsTM cortical inhibitory interneurons can be used in co-culture with axoCellsTM cortical excitatory neurons to investigate the connections in the brain and also monitor the effect of inhibitory neurons on the electrical activity of these excitatory neurons, mimicking conditions such as epilepsy. In order to create more physiologically relevant models, the inclusion of microglia and/or astrocytes is also possible


Mono- and co-culture protocols for interneurons alone or with cortical excitatory neurons are available. In addition, we have protocols for tri-culture with astrocytes or microglia using one media for all cell types. 


As an Early Access Product, these cells will not have been manufactured at our ISO accredited facility and final protocols, documentation and literature may still be development.  

We welcome feedback on these products from the scientific community. These products are available to purchase at a discounted package price and will be supplied with a feedback form.
