Human induced pluripotent stem cell (iPSCs) derived neural models to study brain disease provide an unlimited resource for disease modelling and use as a general research tool. The limited access to viable patient neurons from brain tissue itself generates the need for functional and reproducible human neuron cell models. Such cells are now increasingly used for drug development studies as well as supporting research into mechanisms and pathways of various neurological diseases.
StemRNA Neuro Human iPSCs Neurons
REPROCELL’s StemRNA™ Neuro cells , when cultured, will form a network of mature neurons that develop increasingly dense synaptic connections over time. These cultures can then be used in an array of assays such as assessment of neurite outgrowth, analysis of cell signalling including electrical action potentials, and gene expression analysis.

StemRNA Neuro is a single-cell suspension of late stage progenitor cells prepared from disrupted neurospheres. When the cells are plated in 2D culture plate with microwells, cell aggregation is promoted and spheroid formation is induced over a 24-hour culture phase.
Neurite Outgrowth Assays from REPROCELL
Neurite outgrowth assays are a simple but efficient quantitative method to investigate compounds that effect neurite formation and toxicity.
Induction of neurite outgrowth is performed by transferring generated neurospheres into plates prepared with Neuro Coat. This promotes attachment of the neurospheres and induces neurite outgrowth over the course of the culture phase. For neurite outgrowth assays, 1-2 neurospheres are plated per well to allow neurites to fully form for high quality immunofluorescent imaging, enabling quantification of neurite outgrowth (Number of Neurites per Neurosphere).
