TL;DR: Current knowledge about constitutive adult mammalian neurogenesis is reviewed, the critical differences between neurogenic and nonneurogenic regions in the adult brain are highlighted, and the cardinal features of two well-described neurogenic regions are described.

Abstract: Recent work has shown that the adult central nervous system (CNS) contains neural progenitors, precursors, and stem cells that are capable of generating new neurons, astrocytes, and oligodendrocytes. These findings challenge previous dogma that no new neurons are born in the adult mammalian CNS and raise the possibility of developing novel neural repair strategies. This article reviews current knowledge about constitutive adult mammalian neurogenesis, highlights the critical differences between neurogenic and nonneurogenic regions in the adult brain, and describes the cardinal features of two well-described neurogenic regions – the subventricular zone/olfactory bulb system and the dentate gyrus of the hippocampus. The possibility of repairing neural circuitry by manipulating neurogenesis is reviewed with a focus on recent efforts to understand the conditions under which neurogenesis can be induced in nonneurogenic regions of the adult CNS.

TL;DR: Human blastocyst-derived, pluripotent cell lines are described that have normal karyotypes, express high levels of telomerase activity, and express cell surface markers that characterize primate embryonic stem cells but do not characterize other early lineages.

Apoptosis: a basic biological phenomenon with wide-ranging implications in tissue kinetics.
TL;DR: Apoptosis seems to be involved in cell turnover in many healthy adult tissues and is responsible for focal elimination of cells during normal embryonic development, and participates in at least some types of therapeutically induced tumour regression.

Identification of programmed cell death in situ via specific labeling of nuclear DNA fragmentation.
TL;DR: The extent of tissue-PCD revealed by this method is considerably greater than apoptosis detected by nuclear morphology, and thus opens the way for a variety of studies.
Establishment in culture of pluripotential cells from mouse embryos
TL;DR: The establishment in tissue culture of pluripotent cell lines which have been isolated directly from in vitro cultures of mouse blastocysts are reported, able to differentiate either in vitro or after innoculation into a mouse as a tumour in vivo.
