Abstract To date, no histochemical data exist concerning the process of ossification of developing pedicles in deer. Four different zones of the growing pedicle (subcutaneous tissue; fibrous layer of the periosteum; cambial layer of the periosteum; women bone of the primary spongiosa) were analysed in direct correlation to their histological appearance. The level of extractable specific alkaline phosphatase in the preosseous zones of the pedicle was 4-fold higher than levels in the epiphyseal growth plate previously reported. These results reflect that rapid bone formation takes place in the growing pedicle. Highest buffer-extractable alkaline phosphatase activity was found in the cambial layer directly in front of the mineralization area of the pedicle-bone, connected with maximal values for organically bound phosphate and inorganic phosphate. Moreover, the values for buffer-extractable alkaline phosphatase, organically bound phosphate and inorganic phosphate decreased with increasing mineralization in the zone of the primary spongiosa. The present histological and biochemical findings on the process of ossification in the pedicle show similarities to typical endochondral ossification. The process of pedicle growth may serve as a new and important system for chondrogenic and osteogenic studies, including a better understanding of antler development.
