Electron microscopy analyses. Calcified (a) and fibrotic (b) regions were analyzed by transmission electron microscopy. The presence of dilated mitochondria was detected in numerous hepatocyte-like cells (c) as well as hydroxyapatite deposits within cell cytoplasms (d). Bars indicate either 5 μm (a–c), 1 μm (b) or 2 μm (d).
