Description
Axol Human iPSC-Derived Neural Stem Cells
Axol Human iPSC-Derived Neural Stem Cells (NSCs) are derived from integration-free, induced pluripotent stem cells (iPSCs) under fully defined neural induction conditions. The NSCs express typical markers of cerebral cortical neural stem and progenitor cells such as PAX6, FOXG1 and nestin, and spontaneously form polarized neural tube-like rosette structures when plated as a monolayer in culture (see below). Additionally, Axol NSCs are capable of generating a spectrum of cerebral cortical excitatory and inhibitory neurons that are electrically active and have the ability to form functional synapses and circuits in vitro. After thawing and plating, the neural stem cells terminally differentiate to acquire mature electrophysiological properties, and form functional synaptic networks over a period of 40 ~ 50 days.
Axol NSCs are easy to differentiate to neurons or mixed neural cell types, following our protocols and using our tailored media and reagent bundles. A highly pure population of neurons can be generated from Axol NSCs following the synchronous differentiation protocol. Using our specialized coating reagents, neurons derived from Axol NSCs can be maintained in culture long-term (>1 year). NSCs are available from multiple donors to suit your research needs and have been characterized extensively.

Frequently Asked Questions
For cortical neurogenesis, when do I switch from differentiation media (Diff-XF) to maintenance media NMM-XF?
Nnly move into maintenance media (NMM-XF) when at least 80% of your culture has differentiated to the cortical neurons.
I want to carry out imaging/confocal microscopy, how should I plate the cells?
Plate the cells on Readyset + Surebond (ax0052)
What are the APOE genotypes of the Alzheimers disease Neural Stem Cell products?
Please find attached document.
I want to passage and expand the iPSC-derived neural stem cells, what coating shall I use?
Always plate onto Surebond (ax0041) if you intend to detach the cells for continued expansion
I am not sure what coating I should use for iPSC-derived neural stem cells?
Surebond-XF - Xeno-free coating reagent needed for endpoint assays on plastic, this is the easiest method of coating, with no wash steps. Surebond + Readyset - Coating reagent needed for endpoint assays on glass Surebond- Coating reagent needed when passaging of NSCs is required
How long do I need to expand the cells before I start differentiating the cells?
Each line will need to be assessed to understand it's growth Profile, lines vary however you should aim to passage no more than 2 times Always allow the cells to recover from mitogen treatment for at least a couple of days before going into differentiation. You do not want to differentiate when cells appear flat. Let the cells recover from the flat morphology and assume NSC like morphology before changing media to diff-XF.
