% of BrdU-labeled nuclei associated with specific cell markers
VP + OT
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.
