ioGlutamatergic Neurons
TDP‑43 M337V/WT

Human iPSC-derived ALS and FTD disease model

A rapidly maturing, consistent and scalable isogenic system to study amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

ioGlutamatergic Neurons TDP‑43 M337V/WT are opti‑ox deterministically programmed glutamatergic neurons carrying a genetically engineered heterozygous M337V mutation in the TARDBP gene, encoding TAR DNA binding protein 43 (TDP‑43).

Benchtop benefits

defined_0

Make True Comparisons

Pair the ioDisease Model Cells with the genetically matched wild-type ioGlutamatergic Neurons to investigate the impact of mutant TDP‑43 protein on disease progression.

scalable_0

Scalable

Industrial scale quantities are available with industry-leading seeding densities, and at a price point that allows the cells to be used from research to high throughput screening.

quick_0

Quick

The disease model cells and isogenic control are experiment ready as early as 2 days post revival, and form structural neuronal networks at 11 days.

Technical data

Highly characterised and defined

ioGlutamatergic Neurons TDP‑43 M337V/WT express neuron-specific markers with protein expression highly reminiscent to the isogenic control

ioGlutamatergic_neurons-TDP43-M337V-WT-ICC-VGLUT2

Immunofluorescent staining on post-revival day 11 demonstrates similar homogenous expression of pan-neuronal proteins MAP2 and TUBB3 (upper panel) and glutamatergic neuron-specific transporter VGLUT2 (lower panel) in ioGlutamatergic Neurons TDP‑43 M337V/WT compared to the isogenic control. 100X magnification.

ioGlutamatergic Neurons TDP‑43 M337V/WT form structural neuronal networks by day 11

ioGlutamatergic_neurons-TDP43-M337V-WT-Morphology

ioGlutamatergic Neurons TDP‑43 M337V/WT mature rapidly and form structural neuronal networks over 11 days when compared to the isogenic control. Day 1 to 11 post-thawing; 100X magnification.

ioGlutamatergic Neurons TDP‑43 M337V/WT demonstrate gene expression of neuronal-specific and glutamatergic-specific markers following deterministic programming

ioGlutamatergic_neurons-TDP43-M337V-WT-rt-qPCR

Gene expression analysis demonstrates that ioGlutamatergic Neurons TDP‑43 M337V/WT and the isogenic control (WT) lack the expression of pluripotency makers (NANOG and OCT4), at day 11, whilst robustly expressing pan-neuronal (TUBB3 and SYP) and glutamatergic-specific (VGLUT1 and VGLUT2) markers, and the glutamate receptor GRIA4. Gene expression levels were assessed by RT-qPCR (data expressed relative to the parental hiPSC control (iPSC Control), normalised to HMBS). Data represents day 11 post-revival samples.

Disease-related TARDBP is expressed in ioGlutamatergic Neurons TDP‑43 M337V/WT following deterministic programming

ioGlutamatergic_neurons-TDP43-M337V-WT-rt-qPCR-TDP43

Gene expression analysis demonstrates that ioGlutamatergic Neurons TDP‑43 M337V/WT and the isogenic control (WT) express the TARDBP gene encoding TDP‑43. Gene expression levels were assessed by RT-qPCR (data expressed relative to the parental hiPSC control (iPSC Control), normalised to HMBS). Data represents day 11 post-revival samples.

Disease-related phenotype

Differences in neuronal activity between disease models and control cells by MEA analysis indicates the potential of the panel as a relevant translational in vitro drug discovery model for ALS and FTD

ioGlutamatergic-Neurons-TDP-43-M337V-MEA-analysis-CRL

Reduced neuronal activity was measured in ioGlutamatergic Neurons TDP-43 M337V/M337V compared to ioGlutamatergic Neurons TDP-43 M337V/WT and the isogenic control, ioGlutamatergic Neurons. Microelectrode array (MEA) chips were spotted with 100K (~900K cells/cm2) ioGlutamatergic Neurons (WT), TDP-43 M337V/WT (C20), or TDP-43 M337V/M337V (C1), along with 20K (~180K cells/cm2) human iPSC-derived astrocytes.  Brightfield at 26 DIV (A, left),  cells show good coverage of electrodes and produce clear burst and network burst activity as seen in the raster plot of activity (A, right). In the raster plot, each dash indicates a firing event, blue indicates a single electrode burst and the pink box indicates a network burst event. Quantification of raster plots over the course of culture shows that ioGlutamatergic Neurons TDP-43 M337V/M337V have a lower weighted mean firing rate, and network burst frequency than WT and ioGlutamatergic Neurons TDP-43 M337V/WT (B). No clear difference is noted between WT and TDP-43 M337V/WT. Error bars indicate SEM, n=14 technical repeats. Data courtesy of Charles River Laboratories.

Cells arrive ready to plate

ioGlutamatergic_Neurons_and_disease_models_timeline

ioGlutamatergic Neurons TDP‑43 M337V/WT are delivered in a cryopreserved format and are programmed to mature rapidly upon revival in the recommended media. The protocol for the generation of these cells is a two-phase process: Phase 1, Stabilisation for 4 days; Phase 2, Maintenance, during which the neurons mature. Phases 1 and 2 after revival of cells are carried out by the customer.

Industry leading seeding density

Do more with every vial

ioGlut-WT-well_plate-2

The recommended minimum seeding density is 30,000 cells/cm2, compared to up to 250,000 cells/cm2 for other similar products on the market. One small vial can plate a minimum of 0.7 x 24-well plate, 1 x 96-well plate, or 1.5 x 384-well plates. One large vial can plate a minimum of 3.6 x 24-well plates, 5.4 x 96-well plates, or 7.75 x 384-well plates. This means every vial goes further, enabling more experimental conditions and more repeats, resulting in more confidence in the data.
