A 3D-induced pluripotent stem cell-derived human neural culture model to study certain molecular and biochemical aspects of Alzheimer's disease.

ABSTRACT:

Purpose

Alzheimer's disease (AD) early pathology needs better understanding and models. Here, we describe a human induced pluripotent stem cells (iPSCs)-derived 3D neural culture model to study certain aspects of AD biochemistry and pathology.

Method

iPSCs derived from controls and AD patients with Presenilin1 mutations were cultured in a 3D platform with a similar microenvironment to the brain, to differentiate into neurons and astrocytes and self-organise into 3D structures by 3 weeks of differentiation in vitro.

Results

Cells express astrocytic (GFAP), neuronal (β3-Tubulin, MAP2), glutamatergic (VGLUT1), GABAergic (GAD65/67), pre-synaptic (Synapsin1) markers and a low level of neural progenitor cell (Nestin) marker after 6 and 12 weeks of differentiation in 3D. The
