A non-invasive method to isolate the neuronal linage from the nasal epithelium from schizophrenic and bipolar diseases

► In this study we developed a method to obtain human neural precursors by exfoliation. ► We obtained neural precursors from schizophrenic and bipolar disease patients. ► We cryo-preserved olfactory neural precursors in banks. ► Neural precursors showed cytoskeletal phenotypes typical of developing neurons. ► Neural precursors differentiate morphofunctionally and maintain voltage-operated Ca2+ currents.
