  1. BrdU was administrated to osmotically stimulated rats drinking 2% saline during 6 days, and the animals were fixed 5 hours after the BrdU administration. The relative proportion of each BrdU-labeled cell type was calculated from at least 4 sections per rat in 4 stimulated rats. More than 500 BrdU-labeled nuclei were scored for most markers.
  2. GFAP: glial fibrillary acidic protein; EBA: endothelial brain antigen; NG2: proteoglycan NG2; OT: oxytocin; VP: vasopressin.
