Number of death caused by dementia has doubled in the last 15 years bringing it to the 7th leading cause of global death. Alzheimerâ�?�?s is the main form of dementia Characterized by amyloid-�?² plagues and neurofibrillary tangles. It is critical to establish a relevant disease model in order to understand the pathology of the dementia and also develop a drug. Introduction of 3D cell culture technologies provided us with improved model for cellular research for drug discovery and other medical applications. It was very challenging to create reliable human disease model due to high levels of soluble and insoluble toxic amyloid �?² (A�?²) species that do not recapitulate the true Alzheimerâ�?�?s disease pathology. Recently, Kim et. al created a three-dimensional (3D) human neural stem cell model of Alzheimerâ�?�?s disease using �?²-amyloid precursor protein and presenilin-1 overexpressing ReNcellâ�?¢ VM human neural stem cell lines. This 3D cell model was able to induce robust extracellular deposition of amyloid-�?², including amyloid-�?² plaques, and high levels of phosphorylated tau in the soma and neurites, as well as filamentous tau. This model is a valuable tool to study age-related Alzheimerâ�?�?s dementia as well as other neurodegenerative disorders.
