Vascular microphysiological systems

Curr Opin Hematol. 2024 May 1;31(3):155-161. doi: 10.1097/MOH.0000000000000802. Epub 2024 Jan 18.


Purpose of review: This review summarizes innovations in vascular microphysiological systems (MPS) and discusses the themes that have emerged from recent works.

Recent findings: Vascular MPS are increasing in complexity and ability to replicate tissue. Many labs use vascular MPS to study transport phenomena such as analyzing endothelial barrier function. Beyond vascular permeability, these models are also being used for pharmacological studies, including drug distribution and toxicity modeling. In part, these studies are made possible due to exciting advances in organ-specific models. Inflammatory processes have also been modeled by incorporating immune cells, with the ability to explore both cell migration and function. Finally, as methods for generating vascular MPS flourish, many researchers have turned their attention to incorporating flow to more closely recapitulate in vivo conditions.

Summary: These models represent many different types of tissue and disease states. Some devices have relatively simple geometry and few cell types, while others use complex, multicompartmental microfluidics and integrate several cell types and origins. These 3D models enable us to observe model evolution in real time and perform a plethora of functional assays not possible using traditional cell culture methods.
