Fig. 4. Adult hippocampal neurogenesis in the treatment recipient AD rats. Neurons born during the treatment period were assessed in early-stage (3 months old)
and later-stage (6 months old) male AD rats treated with intravenous injections of (A and D) saline, (B and E) ExPlas, and (C and F) SedPlas. The 6-week treatment
period consisted of 14 intravenous injections, each followed by an intraperitoneal injection of BrdU to label proliferating cells. Single 3.98 mm images showing
immunofluorescent labeling of BrdU (green) and NeuN (red) in a part of the dorsal dentate gyrus that was analyzed to assess the degree of neurogenesis. BrdU/
NeuN-double-labelled cells, seen here in yellow, were quantified as new neurons born during the study period. The yellow arrows point to an example of a BrdU
