PCNA-IR in the mPFC are expressed as the mean ± sem (panel A and panel F). BrdU-IR and BrdU/GFAP-IR cells in the mPFC from animals sacrificed the same day after the last BrdU injection are expressed as the mean ± sem (panel B-E). BrdU-IR and BrdU/GFAP-IR cells in the mPFC from animals sacrificed one week after the last BrdU injection are expressed as the mean ± sem (panel G-J). BrdU/GFAP-IR cells from IT1, IT, Tr and Tr1 groups are are expressed as the mean ± sem (panel K-N).
