ioNEURONS/glut cells have been reprogrammed from human induced pluripotent stem cells (iPSC) using opti-ox, a precise reprogramming technology. Human stem cells, within days, convert into consistent, mature, functional glutamatergic neurons providing a high quality human model for the study of neurological activity and disease.
ioNEURONS/glut cultures consist mainly of glutamatergic neurons (>80%) characterised by the expression of the glutamate transporter genes VGLUT1 and VGLUT2 (see Figure 1). The minor remaining fraction of the neuronal population express marker genes of cholinergic neurons. A bulk RNA-seq analysis shows that ioNEURONS/glut have a rostral CNS identity and express the classical cortical maker genes FOXG1 and TBR1 (data not shown).

Immunocytochemistry of ioNEURONS/glut at day 9 post plating shows homogeneous expression of pan neuronal marker MAP2 and a dense neuronal network. Image courtesy of Charles River Laboratories.
Immunofluorescent staining on post-revival day 11 demonstrates homogenous expression of pan-neuronal proteins (MAP2 and TUBB3) and glutamatergic neuron-specific transporters (VGLUT1 and VGLUT2). Cells exhibit neurite outgrowth.

ioNEURONS/glut display neuronal activity that matures over-time. Examples of MaxOne high-resolution multi electrode array (MEA) recordings of ioNEURONS/glut in BrainPhys™ media. The activity maps show firing rate (A), spike amplitude (B) and % of active electrodes (C) and demonstrate a time-dependent increase of spontaneous activity during neuronal maturation from 2 to 3 weeks post plating.

ioNEURONS/glut show good suitability for high-throughput screening in 384-well format plates. Cytotoxicity CellTiter-Glo® (CTG) assay and a TR-FRET (HTRF) assay for the AKT serine/threonine kinase 1 (AKT) and its substrate the Huntingtin (HTT) were performed on ioNEURONS/glut treated with a tool compound. Compound titration shows concentration response curve in all three assays (mean±sd of 2 replicates). Average signal/background of 2 experiments is excellent for CTG, but lower for both HTRF assays due to lower assay sensitivity.

ioNEURONS/glut are delivered in a cryopreserved format and are programmed to rapidly mature upon revival in the recommended media. The protocol for the generation of these cells is a three-phase process: 1. Induction (carried out at Bit Bio) 2. Stabilization for 4 days with Doxycycline 3. Maintenance during which the neurons mature.
