Abstract/OtherAbstract:
Naturally-occurring cell death is essential to the development of the mammalian nervous system. Although the importance of developmental cell death has been appreciated for decades, there is no comprehensive account of cell death across brain areas in the mouse. Moreover, several regional sex differences in cell death have been described inthe ventral forebrain and hypothalamus, but it is not known how widespread the phenomenon is. We used immunohistochemical detection of activated caspase-3 to identify dying cells in the brains of male and female mice from postnatal day (P)1 to P11. Cell death density, total number of dying cells, and regional volume were determined in 16 regions of the hypothalamus and ventral forebrain(the anterior hypothalamus, arcuate nucleus, anteroventral periventricular nucleus, medial preoptic nucleus, paraventricular nucleus, suprachiasmatic nucleus and ventromedial nucleus of the hypothalamus;the basolateral, central and medial amygdala; the lateral and principal nuclei of the bed nuclei of the striaterminalis; the caudate-putamen, globuspallidus, lateral septum, and Islands of Calleja). All regions showed a significant effect of age on cell death. The timing of peak cell death varied between P1 to P7 and the average rate of cell death varied10-fold among regions. Several significant sex differences in cell death and/or regional volume were detected. These data address large gaps in the developmental literature and suggest interesting region-specific differences in the prevalence and timing of cell death in the hypothalamus and ventral forebrain.
