JANUARY 25TH, 2022 CONN HASTINGS MATERIALS, ORTHOPEDIC SURGERY A team of researchers at the University of Connecticut have developed a biomaterial scaffold that generates small amounts of electricity when compressed. The piezoelectric material is intended to facilitate cartilage regeneration in joints. Normal movement of a joint in which the scaffold is implanted will create repeated small bursts...
UNIVERSITY OF BIRMINGHAM Research published today has demonstrated the viability of 3D-printed tissue scaffolds that harmlessly degrade while promoting tissue regeneration following implantation. The scaffolds showed highly promising tissue-healing performance, including the ability to support cell migration, the ‘ingrowth’ of tissues, and revascularization (blood vessel growth). Professor Andrew Dove, from the University of Birmingham’s School of...
KING ABDULLAH UNIVERSITY OF SCIENCE & TECHNOLOGY (KAUST) KAUST bioengineers have developed a bioprinting process that uses ultrashort peptides as the basis of the scaffolding ink. CREDIT: © 2021 KAUST. A new automated process prints a peptide-based hydrogel scaffold containing uniformly distributed cells. The scaffolds hold their shapes well and successfully facilitate cell growth that...
Near-infrared light is used to precisely engineer stem cells into tissue. Nothing beats nature. The diverse and wonderful varieties of cells and tissues that comprise the human body are evidence of that. Each one of us starts out as a mass of identical, undifferentiated cells, and thanks to a combination of signals and forces, each...
