Penn State researchers 3D print porous tissues for bone and cartilage Implants

December 21, 2018 / TIA VIALVA

Researchers from Pennsylvania State University have created a novel 3D printing method to create tissue building blocks with micropores.
According to the Penn State team, micropores in artificial tissues forming bone and cartilage allow nutrient and oxygen diffusion into the core. By 3D printing stem cells derived from human fat mixed with sodium alginate porogens found in seaweed, the materials can be extruded into tiny particles that, when dissolved, leave behind pores in the fabric of the tissue.
Such additively manufactured porous structures allow both nutrients and other fluids to circulate and demonstrate the potential for lab-grown tissue containing blood vessels.
