Tartrate-resistant acid phosphatase (TRAP) is well known as an osteoclast marker; however, a recent study from our group demonstrated enhanced number of TRAP + osteocytes as well as enhanced levels of TRAP located to intracellular vesicles in osteoblasts and osteocytes in experimental osteoporosis in rats. Such vesicles were especially abundant in(More)
Tartrate-resistant acid phosphatase (TRAP) is known as an osteoclast marker, but osteoblasts and osteocytes in the vicinity of bone remodeling sites also express TRAP. Cell culture studies suggest that osteoblasts endocytose osteoclastic TRAP for inactivation. To evaluate whether changes in osteoclast activity could alter TRAP expression in osteoblasts(More)
OBJECTIVES An experimental rabbit model was used to test the null hypothesis, that there is no difference in new bone formation around uncoated titanium discs compared with coated titanium discs when implanted into the muscles of rabbits. METHODS A total of three titanium discs with different surface and coating (1, porous coating; 2, porous coating +(More)
The main purpose of this study was to examine whether antigens can be retrieved by heating Lowicryl sections of paraformaldehyde-fixed (PFF) tissues. Thus the intensity of the immunogold signal for two bone proteins (Nucleobindin (Nuc) and osteoadherin (OSAD)) was compared in retrieved and non-retrieved sections of PFF rat bone. As an additional experiment,(More)
