タイトル Scraping Assay as a Novel Strategy to Evaluate Axonal Regeneration Using Human-Induced Pluripotent Stem Cell-Derived Neurons.
ジャーナル Biol Pharm Bull
Abstract Neuronal regrowth after traumatic injury is strongly inhibited in the central nervous system (CNS) of adult mammals. Cell-intrinsic and extrinsic factors limit the regulation of axonal growth and regrowth of fibers is minimal despite nearly all neurons surviving. Developing medical drugs to promote neurological recovery is crucial since neuronal injuries have few palliative cares and no pharmacological interventions. Herein, we developed a novel in vitro axonal regeneration assay system to screen the chemical reagents using human-induced pluripotent stem cell (hiPSC)-derived neurons. These neurons were cultured in a 96-well plate to form a monolayer and were scraped using a floating metal pin tool for axotomy. The cell number and plate coating conditions were optimized to score the regenerating axon. Treatment using the Rho-associated kinase (ROCK) inhibitor Y-27632 enhanced axonal regeneration in this regeneration assay system with hiPSC-derived neurons. Therefore, our novel screening method is suitable for drug screening to identify the chemical compounds that promote axonal regeneration after axotomy under in vitro conditions.
