Microanalysis in mitochondrial granules of bone cells incident to experimental tooth movement
Biological functions of Ca in mitochondrial granules have been reported by a number of investigators. It is said that mitochondrial granules of chondrocytes, osteoblasts and osteocytes in rat epiphyseal growth plate with regard to bone calcification and these granules of osteoclasts at bone-resorbing site play an important role of Ca-transport. However, these results were reported about the first stage of calcification in rat epiphyseal growth plate, so that the changes of bone tissues in adult rats seem to be not always the same.The purpose of this work is, by electron probe X-ray microanalysis method, to do the elemental analysis in mitochondrial granules of osteoblasts, osteocytes and osteoclasts incident to experimental tooth movement in adult rats, and to compare them with these analysis in control groups.
