Protocol to generate a microfluidic vessels-on-chip platform using human pluripotent stem cell-derived endothelial cells

Here, we present a protocol for producing a microfluidic vessel-on-chip platform using human pluripotent stem cell-derived endothelial cells (SC-ECs). We describe steps for manufacturing the 3D-printed chip, cell culturing to generate SC-ECs, hydrogel patterning, and the formation and cultivation of barrier-forming vessels. We then detail procedures for the retrieval of cells and media from the open microfluidic chip platform to enable multi-omics analysis. For complete details on the use and execution of this protocol, please refer to Marder et al.¹.
