PAINT with a 3D Printing Pen
August 15, 2023 | Terry Sharrer
“The team [at Nanjing University] developed a system called PAINT, or “portable bioactive ink for tissue healing,” using EVs [extracellular vesicles] secreted from macrophages combined with sodium alginate. These components were combined in a 3D-printing pen, where they mixed at the pen’s tip and formed a sturdy gel at the site of injury within three minutes. The EVs promoted blood vessel formation and reduced inflammatory markers in human epithelial cells, shifting them into the “proliferative,” or growth, phase of healing.” MORE
