20 These are believed to represent a stable population of primitive cells under going regular cell division, in turn giving rise to a population of intermediately differen tiated cells called transient amplifying (TA) cells. These TA cells are thought to divide subsequently, several times,...

Cancer is a group of diseases in which cells divide continuously and excessively. Cell division is tightly regulated by multiple evolutionarily conserved cell cycle control mechanisms, to ensure the production of two genetically identical cells. Cell cycle checkpoints operate as DNA surveillance mechanisms...
CORNEAL EPITHELIAL CELL MIGRATION IN HUMANS: 'HURRICANE AND BLIZZARD KERATOPATHY' H. S. DUA1,2, N. J. WATSON2, R. M. MATHUR3 and J. V. FORRESTER2 Philadelphia, Aberdeen and Ontario SUMMARY Replicative turnover of the corneal epithelium is believed to occur from a population of stem ...
g In silico mapping of mitotic cells onto non-mitotic landscape pinpoints progenitor states of active cell division (upper). To remove effect of mitotic program, mitotic cells were re-positioned as average of 10 transcriptionally similar non-mitotic cells. Comparison of intensity of odontoblast (...
1a,b). We profiled cells in resting state, before dividing (16 h), after the first cell division (40 h) and after acquiring effector functions (5 d)19. This process resulted in high-quality data for 655,349 cells (Methods and Supplementary Fig. 1c–g). Fig. 1: A single-cell...
(Extended Data Fig.4a). At 21 d.p.ci., approximately 54% of same-colour clones were comprised of two or more clonally related cells, indicating cell division (Extended Data Fig.4b–f). Furthermore, we found that 22% of epicardium-derived cardiomyocytes were PCNA+at 21 d.p.ci., ...
Other times, cell-in-cell phenomena have been classified entirely by the outcome of the cell-in-cell event: death of the host and/or death of the internalized cell, division of the internalized cell, or exit of the internalized cell from the host cell14,15,16. There are several open ...
(Extended Data Figs.2and3). Cell types identified in both snRNA-seq and scRNA-seq datasets included fibroblasts, endothelial cells, myeloid cells, pericytes, smooth muscle cells, T cells and natural killer (NK) cells, neurons/glia and B cells. A notable benefit of snRNA-seq is the ability...
