Characterized by the functional deterioration of neurons, neurodegenerative diseases present severe implications for individuals and society. Creative Biolabs has developed several culture systems to study the pathogenesis of neurodegenerative diseases. For example, the human neuroblastoma cell line SH-SY5Y has been widely used for the research of Parkinson's disease (PD); the Lund human mesencephalic (LUHMES) immortalized cell line can be used for neurotoxicity studies.
