Ultrastructural features of osteoclasts and osteoblasts on the medullary bone surface were observed in the cultured bones of laying hens via an electron microscope. The medullary bones were excised from the femur during the formative phase when the eggs were in the magnum of the oviduct and during the resorptive phase when the eggs were in the shell gland of the oviduct. During the formative phase, osteoclasts had abundant cytoplasm but no ruffled border and osteoblasts showed well developed cytoplasm containing a large amount of rough-surfaced endoplasmic reticulum within 48 hours of culturing. These characteristics of osteoclasts and osteoblasts did not differ from those before culturing. During the resorptive phase, on the other hand, osteoclasts had a ruffled border of finger-like cell processes within 72 hours and osteoblasts had poorly developed cytoplasm within 24 hours. These features of osteoclasts and osteoblasts did not differ from those before culturing. These results indicate that the function of osteoclasts and osteoblasts on the medullary bone surface is maintained for a short period of culturing.
