Unlike prokaryotic cells, in which DNA is loosely contained in the nucleoid region, eukaryotic cells possess anucleus, which is surrounded by a complex nuclear membrane that houses the DNA genome (Figure 3). By containing the cell’s DNA, the nucleus ultimately controls all activities of the ce...

heterogenous and some are specialized for producing mucus as a vital physicochemical barrier. In the respiratory and genitourinary tracts, epithelial cells are also endowed with beating cilia, which together with mucus form the mucociliary blanket, which is essential for pulmonary defense and ...
Type C cells are considered to function as ‘transit amplifying’ cells in the neural stem cell niche, namely a bridge between the slow proliferating stem cells and their progeny of neuronal precursors (Doetsch, 2003a; see below). Indeed, the SVZ harbours a population of multipotent neural ...
More generally, a major challenge in identifying genetic interventions that improve the function of old cells is the establishment of scalable genetic screens in mammals. Ageing occurs at both the cell and organismal levels; therefore, it is important to develop screens in vitro in cells from old...
