Apoptosis during embryonic tissue remodeling is accompanied by cell senescence


Figure 5. (A) Transverse vibratome section of an experimental embryo 48 hr after electroporation of Btg2. Note the abundance of cells positive for β-gal activity in the electroporated limb (*). (B) is a detailed view of the limb electroporated with Btg2. As previously reported, β-gal activity is intense in the AER of both control and experimental limbs, in the mesonephros (M) and in the notochord (N).
