Tissue engineering utilizes 3D printing and bioink to grow human cells on scaffolds, creating replacements for damaged tissues like skin, cartilage, and even organs. A team of researchers led by Professor Insup Noh from Seoul National University of Science and Technology, Republic of Korea, has developed a bioink using nanocellulose derived from Kombucha SCOBY (Symbiotic Culture of Bacteria and Yeast) as the scaffold material.
