Perhaps more important is the fact that most of the cells in young leaves have ceased division and are, presumably, at the G1 phase of the cell cycle when CENH3 nucleosomes are stable and fully assembled.
These early experiments showed that cultured human fibroblasts gradually lose proliferative capacity (arrest growth) until all cells in the culture cease division.
It suggested that the expression of synphilin-1 conferred toxicity mainly when cells were ceasing division, while the expression of α-Syn imposed restrictions at different stages during growth.
These early experiments showed that cultured human fibroblasts gradually lose proliferative capacity until all cells in the culture cease division.
The Blagosklonny group used a cancer cell line that ceases division upon inducible, ectopic expression of the cell cycle inhibitor p21.
By the time they cease division, the cells are filled with glucose in the form of trehalose and glycogen (Lillie and Pringle 1980; Li et al. 2013).
Furthermore, we suspect that the observed release of AuNRs from HB1.F3 NSCs in vitro overestimates that which would occur upon transplantation in vivo where NSCs cease division by 48 72 h.
Cells within the prospective sensory vesicle cease division as 13th-generation, with the exception of four cells that become post-mitotic in their 10th (1), 11th (2), or 12th (1) generation.
Overall, these data suggest that PHO84 plays a role in, but is not solely responsible for, signaling the transcriptional response to P. The ability of yeast cells to cease division and attain a stress-resistant state in response to different nutrient limitations was recognized some time ago (Lillie and Pringle 1980; Paris and Pringle 1983).
The resistance of the residual cells may arise from mechanisms such as inaccessibility for anatomical or other reasons, or because of a change in metabolic state which causes these cells temporarily to cease division, when they cannot be harmed by cycle-dependent drugs and repair damage sustained from cycle-independent drugs.
