The present study was designed to investigate the progress of physiological calcification in the bone matrix by using a rat embryonic calvarial organ culture. We analyzed the content and concentration of calcium in the cultured bone matrix for assessing the organ culture system to replicate the progress in calcification.
Abstract: We investigated the extent of calcification on the cell surface of the coccolithophorid Pleurochrysis haptonemofera using flow cytometry. Side scattering (SSC) by coccolith-bearing cells was higher than that by naked cells, suggesting the difference was due to scattering of the laser beam by the coccoliths. SSC of coccolith-bearing cells under acidic conditions corresponded well to the extracellular...
The purpose was to examine the formation and mineralization of molar roots in rats with hypocalcaemia, induced by a low-calcium diet and the changes after returning to a normal diet. Two-week-old male Wistar rats were fed a low-calcium diet (0.03% calcium) during the period when the first molar roots form and then a diet containing normal amounts of calcium (1.83% calcium) was restored. The blood...
