Figure 3. The effects of PRL-deficiency on hippocampal precursor number in vivo.

(A) No difference was observed in proliferation (BrdU-positive cells; A), nor in the generation of new neurons (DCX-positive cells; B) in the hippocampus of PRL−/− mice compared to wild-type littermates (n = 6 animals per genotype). (C) A representative image of BrdU-positive (green) and DCX-positive staining in the PRL−/− hippocampus.
