A, Cells present in clonal clusters were classified based on morphology (see Materials and Methods) into type 1 progenitor cells (A.1); type 2/3 progenitor cells (A.2); immature granule cells (A.3); mature granule cells (A.4), with spiny apical dendrites (A... A, Cells present in clonal clusters were classified based on morphology (see Materials and Methods) into type 1 progenitor cells (A.1); type 2/3 progenitor cells (A.2); immature granule cells (A.3); mature granule cells (A.4), with spiny apical dendrites (A.5); or astrocytes (A.6). B, Immunocharacterization of the different cell types. Type 1 cells were shown to express nestin and GFAP; type 2/3 cells expressed doublecortin (DCX); immature DGCs expressed calretinin; mature DGCs expressed calbindin; and astrocytes were shown to express GFAP. C, The number of clonal clusters per mouse hippocampus was significantly increased in female mice that underwent SE relative to female controls. Female SE mice also had more clusters than male SE mice. D, Graph shows the composition of cell types in clonal clusters from control and SE animals. There was a significant decrease in the number of type 1 cells and a trend (p = 0.06) toward an increase in the number of mature cells in mice exposed to status. E, The percentage of clusters containing either type 1 or type 2/3 progenitors was decreased in SE mice relative to controls, while the percentage of fully differentiated clusters increased. *p < 0.05; **p < 0.01.
