Journal ArticleDOI
Real-time identification of liver cancers by using indocyanine green fluorescent imaging
Takeaki Ishizawa,Noriyoshi Fukushima,Junji Shibahara,Koichi Masuda,Sumihito Tamura,Taku Aoki,Kiyoshi Hasegawa,Yoshifumi Beck,Masashi Fukayama,Norihiro Kokudo +9 more
TL;DR: Fluorescent imaging using indocyanine green (ICG) has the potential to detect liver cancers through the visualization of the disordered biliary excretion of ICG in cancer tissues and noncancerous liver tissues compressed by the tumor.
Journal ArticleDOI
Are animal models useful for studying human disc disorders/degeneration?
Mauro Alini,Stephen M. Eisenstein,Keita Ito,Christopher B. Little,Annette Kettler,Koichi Masuda,James Melrose,James Robert Ralphs,Ian A. F. Stokes,Hans-Joachim Wilke +9 more
TL;DR: Although animal models are invaluable to increase the understanding of disc biology, care must be taken when used to study human disc degeneration and much more effort is needed to facilitate research on human disc material.
Journal ArticleDOI
A novel rabbit model of mild, reproducible disc degeneration by an anulus needle puncture: correlation between the degree of disc injury and radiological and histological appearances of disc degeneration.
Koichi Masuda,Yoichi Aota,Carol Muehleman,Yoshiyuki Imai,Masahiko Okuma,Eugene J.-M.A. Thonar,Gunnar B. Andersson,Howard S. An +7 more
TL;DR: The needle puncture approach, using 16G to 21G needles, resulted in a reproducible decrease of disc height and magnetic resonance imaging grade, which will benefit researchers studying disc degeneration.
Journal ArticleDOI
Platelet-rich plasma stimulates porcine articular chondrocyte proliferation and matrix biosynthesis
Koji Akeda,Howard S. An,Masahiko Okuma,Mohamed Attawia,Kei Miyamoto,E. J-M. A. Thonar,Mary Ellen Lenz,Robert L. Sah,Koichi Masuda +8 more
TL;DR: Platelet-rich plasma isolated from autologous blood may be useful as a source of anabolic growth factors for stimulating chondrocytes to engineer cartilage tissue.
Journal ArticleDOI
Exhaustion of nucleus pulposus progenitor cells with ageing and degeneration of the intervertebral disc
Daisuke Sakai,Yoshihiko Nakamura,Tomoko Nakai,Taishi Mishima,Shunichi Kato,Sibylle Grad,Mauro Alini,Makarand V. Risbud,Danny Chan,Kathryn S.E. Cheah,Ken Ichi Yamamura,Koichi Masuda,Hideyuki Okano,Kiyoshi Ando,Joji Mochida +14 more
TL;DR: In this article, the authors identify populations of progenitor cells that are Tie2 positive (Tie2+) and disialoganglioside 2 positive (GD2+), in the nucleus pulposus from mice and humans.
