Custom 3D In Vitro Model of Ischemic Stroke

Most of the knowledge from in vitro ischemic stroke studies is based on monolayer cultures of neural cells. This traditional simplified culture system is of undisputed importance for stroke research, especially given its relatively low cost and reproducibility compared to animal models. However, two-dimensional (2D) cultures cannot mimic the complex microenvironment experienced by cells in tissues. Unlike cells in 2D culture, in the brain, cells are able to generate 3D projections and establish multiple interactions with other cells and cell types as well as the extracellular matrix (ECM), ultimately affecting their morphology, survival and proliferation, differentiation, gene expression, and even function. Therefore, 3D models of the brain are considered to be more realistic models of the human brain than traditional 2D models and can better simulate its complexity and possible ischemia-induced responses.
