An immunocytochemical method using an antibody against 5-bromo-2'-deoxyuridine has been applied to the study of the kinetics of osteoclast nuclei on intact mouse parietal bones. Osteoclasts containing tartrate-resistant acid phosphatase show nuclei that are positive for the thymidine analogue within 24 hours of injection into four-day old mice. Labelled osteoclast nuclei decline in number with a half-life of 1.3 days, compatible with a random mechanism of cell death rather than a fixed lifespan. This is shorter than has previously been reported and the possible reasons for this are suggested. The main advantages compared with autoradiography are the shortened processing time and the large number of osteoclasts that can be examined per parietal bone.
