Journal ArticleDOI

Jürgen Groll,Jason A. Burdick,Dong-Woo Cho,Brian Derby,Michael Gelinsky,Sarah C. Heilshorn,Tomasz Jungst,Jos Malda,Vladimir Mironov,Koichi Nakayama,Aleksandr Ovsianikov,Wei Sun,Wei Sun,Shoji Takeuchi,James J. Yoo,Tim B. F. Woodfield +15 more
TL;DR: A simple but general definition of bioinks is proposed, and its distinction from biomaterial inks is clarified, to briefly summarize the historic evolution of this term within the field of biofabrication.
Journal ArticleDOI
Scaffold-Free Tubular Tissues Created by a Bio-3D Printer Undergo Remodeling and Endothelialization when Implanted in Rat Aortae
Manabu Itoh,Koichi Nakayama,Ryo Noguchi,Keiji Kamohara,Kojirou Furukawa,Kazuyoshi Uchihashi,Shuji Toda,Jun-ichi Oyama,Koichi Node,Shigeki Morita +9 more
TL;DR: A novel method to create scaffold-free tubular tissue from multicellular spheroids (MCS) using a “Bio-3D printer”-based system and underwent remodeling and endothelialization is developed.
Journal ArticleDOI
Principles of the Kenzan Method for Robotic Cell Spheroid-Based Three-Dimensional Bioprinting*
TL;DR: The future of bioprinting may benefit from the use of gentler scaffold-free bioassembling methods, as a substantial body of evidence has accumulated, indicating this is possible by use of preformed cell spheroids, which have been assembled in cartilage.
Journal ArticleDOI
The efficacy of a scaffold-free Bio 3D conduit developed from human fibroblasts on peripheral nerve regeneration in a rat sciatic nerve model.
Hirofumi Yurie,Ryosuke Ikeguchi,Tomoki Aoyama,Yukitoshi Kaizawa,Junichi Tajino,Akira Ito,Souichi Ohta,Hiroki Oda,Hisataka Takeuchi,Shizuka Akieda,Manami Tsuji,Koichi Nakayama,Shuichi Matsuda +12 more
TL;DR: It is confirmed that scaffold-free Bio 3D conduits composed entirely of fibroblast cells promote nerve regeneration in a rat sciatic nerve model.
Journal ArticleDOI
Fabrication of scaffold-free tubular cardiac constructs using a Bio-3D printer.
Kenichi Arai,Daiki Murata,Ana Raquel Verissimo,Yosuke Mukae,Manabu Itoh,Anna Nakamura,Shigeki Morita,Koichi Nakayama +7 more
TL;DR: The results indicate that these engineered cardiac tubular constructs, which address both the limited supply of donor tissues as well as the immune-induced transplant rejection, has potential to be used for both clinical and drug testing applications.
