Whole transcriptome analysis demonstrates high lot-to-lot consistency across three manufactured lots of ioGlutamatergic Neurons

Bulk RNA-seq data represented in PCA plots demonstrates lot-to-lot consistency of 3 different lots of ioGlutamatergic Neurons.

Bulk RNA-sequencing analysis was performed on three different lots of ioGlutamatergic Neurons on day 0, day 11 and day 18 post-revival. (A) A principal component analysis (PCA) to assess gene expression variance between three different manufactured lots showed a tight clustering of the samples at each timepoint, demonstrating high consistency between these lots. This lot-to-lot consistency of ioGlutamatergic Neurons will help reduce experimental variation and increase the reproducibility of experiments. (B) PCA without the parental non-induced hiPSC samples, highlighting the tight clustering of the day 11 as well as day 18 samples of the three different lots. (C) Differential expression test reveals no statistically significant differentially expressed (DE) genes across the three lots at day 11 (|logFC| > 0.5 and FDR < 0.01).

Colours represent the three lots of products; shapes represent the parental non-induced hiPSC line and different timepoints.

High lot-to-lot consistency is demonstrated by a consistent transcriptomic fingerprint across manufactured lots of ioGlutamatergic Neurons

Single cell RNA-seq data represented in UMAP plots demonstrates lot-to-lot consistency of 3 different lots of ioGlutamatergic Neurons.

Single cell RNA-sequencing analysis was performed on three different lots of ioGlutamatergic Neurons on day 11. UMAP plots represent the cell-to-cell variation in gene expression profiles of cells, each dot representing an individual cell. Cells from each of the three lots are equally distributed across the body of the plot. Merging the UMAP plots creates a tight overlay, showing a strong transcriptional relationship between cells from three independently manufactured lots of ioGlutamatergic Neurons. Gene expression was assessed by 10x Genomics scRNA-sequencing.

Single cell ATAC-sequencing shows a consistent transcriptomic fingerprint demonstrating high lot-to-lot consistency across manufactured lots of ioGlutamatergic Neurons

Single cell ATAC-seq data represented in UMAP plots demonstrates lot-to-lot consistency of 3 different lots of ioGlutamatergic Neurons.

Single cell ATAC-sequencing analysis was performed on three different lots of ioGlutamatergic Neurons on day 11. Single cell ATAC-sequencing reveals regions of open chromatin to understand the gene regulatory landscape of individual cells. UMAP plots represent the cell-to-cell variation in chromatin accessibility of the cells, each dot representing a single cell. Cells from each of the three lots are equally distributed across the body of the plot. Merging the UMAP plots creates a tight overlay, showing a strong transcriptional relationship between cells from three independently manufactured lots of ioGlutamatergic Neurons. Gene expression was assessed by 10x Genomics scRNA-sequencing.

Rapid gain of functional activity

ioGlutamatergic Neurons display neuronal activity that matures over-time

Examples of MaxOne high-resolution multi electrode array (MEA) recordings of ioGlutamatergic Neurons in BrainPhys media. The activity maps show firing rate (A), spike amplitude (B) and % of active electrodes (C). Results demonstrate a time-dependent increase of spontaneous activity during neuronal maturation from 2 to 3 weeks post-revival.

Array Wide Spike Detection Rate histograms (AWSDR – a graphical measure of synchrony) for 10-minute recordings on day 8, 13 and 20 post-revival ioGlutamatergic Neurons in co-culture with primary rat-derived astrocytes. Results show prominent synchronicity on day 13, exemplified by the ‘spikier’ nature of the associated AWSDR, which increases at day 20. Cells were cultured in the bit.bio recommended open-source medium and recorded on 64-electrode MEAs.

Robust and scalable cells for high-throughput screening

ioGlutamatergic Neurons show good suitability for high-throughput screening in 384-well format plates

Cytotoxicity CellTiter-Glo®️ (CTG) and TR-FRET (HTRF®️) assays for AKT serine/threonine kinase 1 (AKT) and Huntingtin (HTT) proteins were performed on ioGlutamatergic Neurons in 384-well plates treated with tool compound (cmp) at day 9 post-revival. Compound titration results in a concentration response curve for all three assays (mean±sd of 2 replicates). CTG assay on ioGlutamatergic Neurons shows an excellent average signal/ background ratio and high suitability for HTS. HTRF® assays on ioGlutamatergic Neurons show lower signals but with low variability, and could therefore also provide a suitable platform for HTS.

Industry leading seeding density

Do more with every vial

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.

bit.bio_ioGlutamatergic_Neurons_WT_timeline

ioGlutamatergic Neurons 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: 1. Stabilisation for 4 days 2. Maintenance during which the neurons mature.
