Cover Story: A new class of porous 3D dual network composite hydrogel scaffolds with osteogenic ions: Ca2+, Zn2+, and Sr2+ was developed by sequential formation of the networks with differences in the ion-alginate affinity, accounting for the differences in properties. These composites resembled the morphology of trabecular bone with high interconnectivity and isotropy, allowing cells to thrive and to evenly dissipate energy from multidirectional loads. The simple fabrication process and low costs of these scaffolds with osteoinductive properties thus have translational potential to replace autografting in bone defects, especially for oral and maxillofacial surgery.

Delivery of Bioactive Compounds to Improve Skin Cell Responses on Microfabricated Electrospun Microenvironments

  • David H. Ramos-Rodriguez,
  • Sheila MacNeil,
  • Frederik Claeyssens and
  • Ilida Ortega Asencio

The introduction of microtopographies within biomaterial devices is a promising approach that allows one to replicate to a degree the complex native environment in which human cells reside. Previously, our group showed that by combining electrospun f...
