Apoptosis during embryonic tissue remodeling is accompanied by cell senescence
Figure 6. Selection of areas of embryonic programmed cell death showing the parallelism between the distribution of neutral red vital staining (A′, B′, C′) and β-gal activity (A, B C). A-A′: cell death (arrows) during the closure of the lens in chick embryos at 2.5 id. B-B′ cell death in the AER in the embryonic limb at id 3.5. C-C′, cell death in the root of the main arteries of the embryonic heart at id 7.5.
