Public Release: 14-Feb-2018 Case Western Reserve University researchers engineer natural windpipe replacement alternative to synthetic scaffolding now being used Case Western Reserve University Biomedical engineers at Case Western Reserve University are growing tracheas by coaxing cells to form three distinct tissue types after assembling them into a tube structure-without relying on scaffolding strategies currently…
Novel bio-ink comprises flake-shape microgels and living cells that can produce cartilage-like tissues and other complex living constructs.
New 4D Hydrogels can Change Shape in Response to Stimuli Written by AZoMMar 2 2021 For a long time, tissue engineering has relied on geometrically static scaffolds that are seeded with cells in the laboratory to make new tissues and even organs. 4D hydrogel-based materials can undergo multiple conformational shape changes in response to environmental cues.

Generally, the scaffolding material is a biodegradable polymer structure that is provided with cells, and if the cells are supplied with proper nutrients, then they develop into a tissue as the basic scaffold bio...
E-Mail IMAGE: 4D hydrogel-based materials can undergo multiple conformational shape changes in response to environmental cues view more Credit: Aixiang Ding Tissue engineering has long-depended on geometrically static scaffolds seeded with cells in the lab to create new tissues and even organs. The scaffolding material -- usually a biodegradable polymer structure -- is supplied with cells and the cells, if supplied with the right nutrients, then develop into tissue as the underlying scaffold biodegrades. But this model ignores the extraordinarily dynamic morphological processes th...
New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers at the University of Illinois Chicago.
