Highlights
Materials Today
Bioengineers have created three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can be kept alive in the lab for more than two months.
The University of Edinburgh
Scientists have for the first time grown a complex, fully functional organ from scratch in a living animal by transplanting cells that were originally created in a laboratory to form a replacement thymus, a vital organ of the immune system.
Materials Today
Repairing damaged cartilage, which allows the smooth motion of joints, can require surgery to implant donor tissue grafts. A potentially better solution would be the fabrication of custom-made graft tissue scaffolds that enable cartilage cells to recolonize damaged areas and produce new tissue. A new bioink devised by researchers could allow just such three-dimensional cartilage tissue scaffolds to be printed at room temperature.
Ann & Robert H. Lurie Children's Hospital of Chicago
The research group of Arun K. Sharma, PhD has developed a system for patients with urinary bladder dysfunction that may protect them against an inflammatory reaction resulting from tissue regeneration, which can negatively impact tissue growth, development and function.
MIT News
MIT chemical engineers have devised a new treatment for bone injuries or defects: an implantable tissue scaffold (structure) coated with bone-growth factors that can be released slowly over a few weeks to induce the body to rapidly form new bone that looks and behaves just like the original tissue.
Kurzweil Accelerating Intelligence
A biomaterial that can regenerate damaged skeletal muscle is being developed by University of Arkansas biomedical engineering researcher Jeffrey Wolchok, funded by a National Institutes of Health three-year, $437,248 grant.
