Overview
Neurological disorders impose a substantial burden of disability and morbidity globally. As the population grows and ages, the anticipated increase in these disorders necessitates advancements in neurological research. A significant challenge in studying these diseases is the difficulty in accurately culturing, monitoring, and analyzing neuronal cells due to their delicate nature and limited ability to proliferate. Induced pluripotent stem cells (iPSCs), which can differentiate into neurons, present a promising solution.
However, traditional culture methods often use animal-derived components, raising concerns about experimental validity and potential contamination risks. In this application note, we investigated optimized culture methods using human iPSC-derived neuronal and astrocytic cells with xeno-free coatings from Advanced BioMatrix (ABM). We assessed neuron outgrowth and excitotoxic response on ABM-coated plates, finding that dual-coating with ABM solutions significantly enhanced neurite outgrowth and showed a concentration-dependent reduction in neurites in both monoculture and co-cultures. Further analysis using a neuronal activity assay revealed correlated calcium burst activity, indicating the presence of functional synapses. Overall, these findings underscore the potential of integrating iPSC-derived neurons, xeno-free coatings, and live-cell analysis to develop accurate and reproducible neuronal models, thereby advancing research in neurological diseases.
