Human iPSC-Derived Neural Stem Cells that have been genetically edited using CRISPR-Cas9 technology to introduce the P301L mutation (CCG>CTG) into the MAPT gene. This line is heterozygous for the P301L mutation where one allele contains the mutation and the other allele is wild type at the locus. Click on the product images to see the data and further details.

The P301L mutation MAPT has been implicated in frontotemporal dementia and parkinsonism (Dumanchin et al., 1998). The mutation affects only the 4R isoforms of MAPT since the exon containing the mutation is spliced out of 3R isoforms (Hutton et al., 1998). Aggregated MAPT/tau protein in affected patients consisted mainly of the 4R isoform (Hutton et al., 1998). The P301L mutation promotes aggregation of MAPT/tau protein into ordered paired helical filaments and beta sheet formation in vitro (von Bergen et al., 2001).

Frequently Asked Questions

Plate the cells on Readyset + Surebond (ax0052)

Always plate onto Surebond (ax0041) if you intend to detach the cells for continued expansion

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 or 96-well plates Surebond- Coating reagent needed when passaging of NSCs is required

Please switch to the Maintenance Medium-XF after the suggested period of Neural differentiation medium-XF treatment (see page 12 and 15 of the Human iPSC-Derived Neural Stem Cell Master Protocol below).

Please make sure you change medium gently and avoid adding the medium from one side of the wells throughout the 5-6 weeks of culture. If the cells start to peel from the corners, it can be repaired by adding Surebond (ax0041) into your standard feeding media. Usually, we use 120 uL Surebond in 12 mL medium for a few days until the layer re-attach. This can be applied no matter what coating has been used.

We do not recommend using coating reagents whcih we have not tested with our cells. They might result in poor quality cultures and low adherence. Our SureBond, SureBond-XF and SureBond+ReadySet have been optimized to complement our cells and provide consistent results.

We do not recommend re-freeze the NSCs. Axol cannot guarantee the viability of the iPSC-derived NSCs and functionality of the neurons derived after re-freezing.

A long expansion period will increase the number of glial cells in your final population. We recommend conducting fewer passaging steps (< 3 passages) over a shorter period of time in order to reduce the glial cell population.

It is possible to achieve a 90% pure population of cerebral cortical neurons after terminal differentiation using Neural Differentiation-XF Medium (System B). Repeated expansion of the NSCs will increase the glial population and conversely decrease the neuronal population.

The ratio of deep to upper layer neurons will change with the number of days in culture. After 2 weeks in Neural Maintenance-XF Medium, approx. 60% of neurons express deep layer markers but this will decrease with length of time in culture. We would recommend spontaneous differentiation for over 40 days to see a large percentage of upper layer neurons.  

At day 21, spontaneous synaptic activities should be detected, and day 35 synchronised burst firing should occur.

Yes, Axol iPSC-Derived Cortical Neurons when co-cultured with astrocytes have been shown to respond to high frequency stimulation resulting in a change in spike frequency presenting as a depression of potentiation of network transmission.

We typically use PAX6, SOX2, Nestin, FOXG1, OTX, ASPM, N-cadherin and Ki67 to identify NSCs.

NeuN, TBR1, TUJ1, MAP2, GAD67, VGLUT1, Synaptophysin, CTIP2, CUX1 and BRN2 can be used to identify cerebral cortical neurons.
