Background:

Cell-extracellular matrix (ECM) interactions are crucial for cellular function and phenotype.
Microscale approaches offer high-throughput assessment of the ECM microenvironment's effects on cells.

Purpose of the Study:

To characterize the generation of multicomponent ECM microarrays using microscale direct writing (MDW).
To evaluate the impact of patterned ECMs on endothelial cell attachment and stem cell fate determination.

Main Methods:

Microscale direct writing (MDW) technique used to print ECMs and biomolecules onto glass substrates.
Generation of multicomponent ECM microarrays with gelatin, collagen IV, and fibronectin.
Culturing human endothelial cells and murine embryonic stem cells (ESCs) on the generated microarrays.

Main Results:

Endothelial cells showed preferential attachment and cytoskeletal alignment along patterned ECMs.
ESCs maintained pluripotency markers on ECM microarrays in the presence of leukemia inhibitory factor.
ESCs differentiated towards the ectodermal lineage, with gelatin promoting higher pan cytokeratin expression compared to collagen IV or fibronectin.

Conclusions:

MDW is a versatile method for printing diverse ECM geometries and compositions.
ECM microarrays generated by MDW are suitable for stem cell fate determination.
Specific ECM components differentially influence stem cell differentiation pathways.
