  STOP null mice and their WT littermates were generated on a mixed BALBc/129 SvPas and on a pure 129 SvPas background as previously reported by Andrieux et al. [4]. All animals used in the study underwent immunohistochemistry for the detection of STOP protein, resulting in no staining in STOP null mice, and genotyping by PCR as described by Andrieux et al. [4]. All mice were kept under standard housing conditions with a 12-hour/12-hour dark-light cycle. The experiments were carried out in accordance with the European Communities Council Directive of 24 November 1986 (86/609/EEC), and the French Department of Agriculture (License Ndegrees 67-95). The protocol was approved by the ethical Animal Research Committee of Louis Pasteur University (CREMEAS #AL/01/19/10/07).
  In a first experiment, we searched for differences in glomerular ultrastructure and peripheral neurogenesis between WT and STOP null mice: a first group of 24 mice, 3- to 6- month-old, was used for ultrastructural study of the OBs; a second group of 13 animals was used to analyse proliferation and apoptosis in the OE and VNE on paraffin sections in 3-month-old mice. In a second experiment we analysed, in WT and STOP null mice, the effect of OE regeneration on glomeruli structure and ultrastructure and on peripheral neurogenesis at two age times (3 and 10 months).
