On the cover: Scanning electron micrographs of kidney sections from 15-week-old podocyte-specific p53^+/+ or p53^-/- wild-type (WT) or Alport (AS) mice. Foot process effacement is observed in AS mice, which was exacerbated by knockout of p53. Numerous filopodia formed on the zipper-like structures in podocytes of pod-p53^-/- AS mice. Bars, 1 μM. Original magnification, x10,000. Ryosuke Fukuda, Kumamoto University, Japan
