Control sections.

<p>Sections are toluidine stained in (A-H). Both the WT mice and The ZnT3-KO mice display a normal morphology 24 hours after respectively DEDTC and selenite treatment. The tissue is without oedema and the cells are all intact with normal configuration. A, B, E, F are Cryo-sections 30 µm thick. C, D, G, H are semi-thin sections 3 µm thick. No major differences between the ZnT3-KO and the WT mice are noticeable. Scale bar A,B: 100 µm. Scale bar E: 200 µm. Scale bar F: 300 µm. Scale bar C, D, G, H: 30 µm. Control sections, FJB stained (I-L). Sections I, J are pretreated with DEDTC and sections K, L are pretreated with selenite. All sections are FJB negative. Control sections, TUNEL stained (M-P). Sections M, N are pretreated with DEDTC and sections O, P are pretreated with selenite. All sections are TUNEL negative. M, P depict part of the hippocampus formation and N, O depict all the six neocortical layers. Scale bar I-P: 200 µm.
