Cell-based microarrays are valuable platforms for the study of cytotoxicity and cellular microenvironment because they enable high-throughput screening of large sets of conditions at reduced reagent consumption. However, most of the described microarray technologies have been applied to two-dimensional cultures, which do not accurately emulate the in vivo three-dimensional (3D) cell-cell and cell-extracellular matrix interactions.Herein, we describe the methodology for production of alginate- and Matrigel-based 3-D cell microarrays for the study of mouse and human pluripotent stem cells on two different chip-based platforms. We further provide protocols for on-chip proliferation/viability analysis and the assessment of protein expression by immunofluorescence.
