Recent advances in stem cell technologies offer an exciting alternative to rodent models for investigating the human nervous system and neurological disorders.  The ability to simultaneously monitor morphology and functional readouts over time is critical for thorough characterization of human induced pluripotent stem cell (hiPSC)-derived models. Typically endpoint assays of subtype-specific surface marker expression and morphological features are employed. These techniques have proven valuable, but they fail to couple insight into the ability of these cells to exhibit neuronal activity and develop mature networks. In the case of hiPSC-derived microglia, it is important to ensure that these cells are capable of critical neuroimmune functions such as phagocytosis and chemotaxis.  Here we present live-cell imaging data used to quantify functional readouts of hiPSC-derived neurons and microglia and qualitatively assess morphology using the IncuCyte® for Neuroscience. Monitoring of differentiating neuro-progenitor cells (Axol Bioscience) enabled the maturation to iPSC-derived neurons to be visualized over >80 days, with marked morphological and functional development. Activity of hiPSC-derived glutamatergic and GABAergic neurons (CDI, iCell Neurons) was visualized and analyzed using the Incucyte® NeuroBurst reagent, a genetically encoded calcium indicator. While both neuronal types exhibited spontaneous activity, only glutamatergic neurons developed coordinated synaptic network activity over time in culture.  To exemplify the benefit of long term monitoring of these models, the CNS.4U® (NCardia) co-culture model of hiPSC-derived neurons and astrocytes were evaluated for over 40 days. While spontaneous activity was detected after one week, correlated network bursting was only observed after 30 days in culture. Finally, hiPSC-derived microglia (Axol Bioscience) were monitored for morphological changes following differentiation and evaluated for phagocytic potential by use of a pH sensitive dye.  Collectively, these data illustrate the ability to monitor and characterize hiPSC-derived neuronal cultures and support cells over time using live-cell analysis techniques.
