Figure 2From: The effect of calcium phosphate nanoparticles on hormone production and apoptosis in human granulosa cellsTEM observation of granulosa cells exposed to calcium phosphate nanoparticles. Cells were exposed during 72 h to 100 μM of nanoparticles. Nanoparticles were internalized in cells and localized in cytoplasms, mostly in membranate compartments, including lysosome and mitochondria, thecal organelles (arrow). The scale bar in the image is 500 nm.Back to article page
