Figure 4From: Amnion formation in the mouse embryo: the single amniochorionic fold modelAbsence of apoptosis in the amniochorionic fold of embryos undergoing exocoelom formation. (A-B) TUNEL assay in sections of embryos showing absence of programmed cell death in extraembryonic mesoderm during the process of exocoelom formation. Apoptotic cells were readily detected in the ectoplacental cone. Scale bar: 200 μm.Back to article page
