On the cover: Intravital image of a glomerulus in a healthy Confetti/ Podocin:Cre mouse. Capillaries were marked by a single injection of DyLight594-labeled tomato lectin (red). Podocytes are visible in yellow (cytoplasmic YFP) and light-blue (membrane-tagged CFP). Collagen fibers are visualized by second harmonic signal generation (dark blue) and the surrounding tubules are visualized by autofluorescence. Sebastian Brähler and Bernd H.
