Electron micrographs of syncytiotrophoblastic mitochondria (arrows) at different gestational ages demonstrating the distortion of the cristae and dilatation of the intracristal space that coincides with Hsp 70 expression and the formation of nitrotyrosine residues at 6 weeks (a), 10 weeks (b), 14 weeks (c). d: Scattergram plot of the percentage mitochondrial volume occupied by intracristal space at different gestational ages. The line was fitted using the LOWESS technique with a tension of 66.
