Potassium concentration in membrane-associated particles in the epiphyseal growth plate


Electron-dense particles with a diameter of 50–200 nm have been observed at the cell membrane of chondrocytes in the zone of the initiation and advance of mineralization, using the dark field STEM mode. Electronprobe x-ray microanalysis and laser microprobe mass analysis indicate that these particles contain predominantly K and Na. They appear only in dry… (More)
