The “Cell Death Atlas” is a project started several years ago by Todd H. Ahern & Nancy G. Forger to map naturally occurring cell death in the mouse brain during the late prenatal and early postnatal period. The atlas comprises scanned microscope slides of ~275 mouse brains of both sexes, age embryonic day 17 through postnatal day 11. All brains have been frozen sectioned, immunohistochemically stained for the cell death marker activated caspase 3 (AC3), and counterstained with thionin.
The first part of the atlas covers postnatal day 1 through 11 and is the subject of a publication (Ahern et al., 2013). We have recently expanded the atlas to include earlier time points [embryonic day (E) 17, 18, and 19, and postnatal day 0].
A sample “page” from the atlas is shown below. Each image can be zoomed up to 400X equivalent magnification.
