...Yasuhito Yahara; Tuyet Nguyen; Koji Ishikawa; Katsuhiko Kamei; Benjamin A. Alman ABSTRACT The mechanisms underlying bone development, repair and regeneration are reliant on the interplay and communication between osteoclasts and other surrounding cells. Osteoclasts are multinucleated monocyte...

... expand and are resorbed by osteoclasts then replaced by osteoblastic bone formation. Ephrin B2 is a receptor tyrosine kinase expressed by osteoblasts and growth plate chondrocytes that promotes osteoblast differentiation and inhibits osteoclast formation. We investigated the role of ephrin B2...

... and osteoclasts using immunohistochemical staining analysis with specific TGF- β antibodies. TGF- β s in osteoclasts and chondroclasts were restricted to those cells located on the respective matrices. TGF- β 3 localization was mainly cytoplasmic in the transitional (early hypertrophic) chondrocytes, but nuclear...
