Reduced endosomal staining in OCRL1 deficient pronephros.

<p>A-C. Confocal transverse sections of the zebrafish proximal pronephric tubule of 72 hpf wild-type (WT) and <i>ocrl^-/-</i> mutant embryos labelled with antibodies to EEA1 or endofin (A), or to GFP (B and C) to detect expressed GFP-Rab11 (B) or GFP-Rab7 (C). White dashed lines indicate the outline of pronephric tubules. Scale bars represent 10 μm.
