3D Stone Cells

These were really weird glowing things under differential interference contrast, so here I used an image stack of three focal points and combined them using CombineZM which makes it look even weirder. They're Pyrus stone cells (prepared slide from Carolina Biologicals) observed with the 20x objective on an Olympus IX81 microscope. The glowing stony material is secondary cell wall; the lines radiating from the center of the cells are plasmodesmata. You can't really see them very well on the single images, but they show up nicely after focus stacking.
