Sentences with phrase «phase of the cell cycle»

These are other proteins that are periodically formed and again broken down during the various phases of the cell cycle.

There are as many as 14, but the scientists found that cyclin D adds just a single phosphate at one, and only one, of the 14 locations during the early G1 phase of cell cycle progression, essentially make 14 different versions of the Rb tumor suppressor.

According to Wikipedia, old pores are disassembled and assembled during different phases of the cell cycle.

(B) FACs analysis of the cell cycle in proliferating hNSCs, hESCs, and iPS cells with a chart showing percentages of cell types in the G2 / M phase of the cell cycle.

Additionally, human - specific mouse anti-Ki67 (1 ∶ 50, Dako) revealed any human cells in active phases of the cell cycle.

Overgrown cultures stimulate quiescence, the resting phase of the cell cycle; quiescent cells do not take up nucleic acid or express transgenes as well as actively dividing cells resulting in lower lentiviral titers.

During the mitotic phase of the cell cycle, the duplicated genome in the form of condensed chromosomes is partitioned to the daughter cells.

ActD has been shown to have a reversible cytostatic effect and the ability to arrest cells in both the G1 and G2 phase of the cell cycle [17].

Quantification of this data showed that hNSC - derived iPS cells were more similar to hESCs in the percentage of cells in the G2 / M phase of the cell cycle than were hNSCs (Figure S1b).

Cells maintained the expression profile they had displayed prior to grafting and had largely exited active phases of the cell cycle (Ki67 negative).

It has been shown that mTOR inhibition by rapamycin arrests cells in G1 phase of the cell cycle and there is evidence that this inhibitory effect occurs via the inhibition of activation of p70S6K1 and 4E - BP1 (45).

In this new study, licensing refers to origin licensing, the process of helicase loading onto DNA for genome duplication purposes during the G1 phase of the cell cycle.

Expression occurs preferentially during late G1, S, G2 and M phases of the cell cycle, while in cells in G0 phase the antigen can not be detected (at protein level)(PubMed: 6206131).

Importantly, differentiated cells were negative for RPE cell de-differentiation marker, KRT8 [9] and a marker of the active phase of cell cycle, Ki67, indicating cells were no longer proliferative (Fig. 3).

In the 1990s, researchers were beginning to understand the ways cells regulate transitions into the four phases of the cell cycle: G1, synthesis (S) phase, G2, and mitosis.
