Composite biomaterial scaffolds enable patterning of tissue architecture and cell identity

(Institute of Neural Regeneration & Tissue Engineering) New designs are described for unique biomaterial scaffolds that incorporate patterned architectures and regional compartments of signaling factors that can more intricately guide stem cell development. These designs enable more comprehensive control over cell fate and tissue architecture, and also establish a platform for studying the effects of concentration gradients of a variety of signaling factors on tissue development.
