Selected images showing the effect of sub-lethal doses of cadmium on INS-1 cells mitochondria. Mitochondrial morphology was followed by staining a mitochondrial protein of the matrix, aconitase (green). The nucleus was stained by PI (red). INS-1 cells were treated for 96 h with (a) 0 and (b) 2 μM CdCl₂. Scale bars 10 μm.
