Dongeun Huh and co-workers present a placenta on a chip that can be used as a screening platform to study and predict drug transport in pregnancy from the mother to the fetus. This microengineered model is designed to recapitulate the multilayered 3D architecture of the placental barrier including efflux transporter-mediated transport of test compounds. Within the microfluidic device, trophoblast and endothelial cells are cocultured on the opposite sides of a thin porous polymeric membrane.

This Review Article gives an overview of the biochemical, mechanical, and structural considerations for hierarchical design of materials for tissue regeneration. The work brings together ongoing approaches to fabricate implantable and injectable scaffolds with hierarchical organization to create new technologies that have the potential to widen the scope of tissue engineering and increase the opportunities for translation to the clinic.

Hydrogels are under active development for controlled drug delivery, but the clinical translation of hydrogel delivery systems faces hurdles, including low drug loading capacity, deficiencies in mechanical toughness and storage stability, and poor control over the drug release. David Mooney and colleagues report a design of composite clay hydrogels, which simultaneously achieve a spectrum of mechanical, storage, and drug loading/releasing properties to address the critical needs from translational perspectives. The clay nanoparticles provide large surface areas to adsorb biological drugs, and assemble into microparticles that are physically trapped within and toughen hydrogel networks. A rodent model of Achilles tendon injury is used to demonstrate that the composite hydrogels allow highly extended and localized release of biological drugs in vivo, while demonstrating biodegradation and biocompatibility. These composite hydrogels may aid the clinical translation of hydrogel drug delivery systems for biological drugs.
We recently have released top-level special issues on biomimetic interfaces in biomedical devices and microphysiological analytic platforms (MAPs): precision organs on chip.
