At the G2/M transition it undergoes significant cell cycle-specific reorganizations and matures into the division-competent center of the mitotic poles.
It is unclear what these 'positional cues' are, although we do know that division competent cells in both the mouse mammary gland and the human breast are separate from, but adjacent to cells that express receptors for oestrogen, implying that this steroid controls proliferation indirectly [ 9, 10].
This accelerated senescence of WS cells in vitro has been postulated to correspond to a similar process in vivo, and thus contribute to the accelerated ageing of division-competent tissues (Ostler et al. 2002).
AILs also play a role in the specification of meristematic or division-competent states [ 76].
In the first instance we demonstrate a synergy of action between two products of the first gene cluster, (PknA and the FHA domain protein FipA), and two products of the dcw cluster (FtsZ and FtsQ) in maintaining cells in a division-competent state under oxidative stress.
BOB1 transcripts accumulated in tissues, such as shoot apices, developing rosette leaves and roots, that contain division-competent cells (Fig. 5B).
In the aerial parts of the transgenic plants, signals due to GFP were most abundant in shoot apices with developing leaves (Fig. 5C), which contain strongly division-competent cells.
There is rarely a division of labour within an industry in nonliterate communities, except perhaps for the production of larger goods (such as houses or canoes); in these cases the division is often a temporary one, and each worker is competent to perform other phases of the task.
Although an extremely competent administrator, there were reservations within the New Zealand government following Godley's appointment as commander of the division.
Adventitious root forming treatments induce root meristem patterning genes, such as GRAS genes, before the onset of cell division in competent cells.
The division was also supposed to hire a consultant (because the station is registered as a national historic place and the division's engineers did not feel competent for the job) to repair the ceiling permanently.
