“…Although the increase in the absolute number of cells predicted to die can be explained in part by the increased founder cell population in primates, as more cells are generated, the predicted percentage of cells that die is also considerably higher in primates versus rodents. Quantitative measurements of TUNEL(+) or pyknotic cells suggest similar percentages of death labeled cells are evident at any one time during human and rodent neocortical development, varying between 0.1% and 0.4% (Hoshino and Kameyama 1988;Thomaidou et al 1997;Chan and Yew 1998;Haydar et al 1999;Rakic and Zecevic 2000;Anlar et al 2003). Some researchers have suggested higher death rates in the proliferative zones (Blaschke et al 1998), however, these results may be an artifact of the technique used (Gilmore et al 2000), and are not supported by previous experiments cited above, experiments using retroviral labeling techniques (Cai et al 2002), or computational models comparing different techniques for detection of cell death during neocortical neuronogenesis in the mouse and rat (Gohlke et al 2004).…”

“…Apoptosis is a key process during brain formation, controlling cellularity in the developing brain [ 25 , 26 ]. Work in human [ 27 ], mouse [ 26 ], and rat [ 28 ] brain samples shows high incidence of cell death during the development of the neocortex. As the overall architecture of the organoids was maintained, the observed cell death may be the result of the normal elimination of cells that takes place in the developing brain.…”

“…Την κατανοµή της απόπτωσης στον εµβρυϊκό ανθρώπινο εγκέφαλο µελέτησε, ανάµεσα σε αρκετές οµάδες, και µια οµάδα, η οποία βρήκε ότι στα φυσιολογικά έµβρυα τα TUNEL-θετικά κύτταρα ήταν περισσότερο συγκεντρωµένα στη διάµεση ζώνη (intermediate zone, IZ) και µεταξύ της 18 ης και 22 ης εβδοµάδας κύησης. Επιπλέον, ένα έµβρυο που έπασχε από υδροκέφαλο παρουσίαζε αυξηµένο αριθµό TUNEL-θετικών κυττάρων (Anlar et al, 2003).…”
