However, when IMR-32 cells were cotreated with SB203580 and etoposide, the formation of NBSs was totally prevented, even from the first passage (data not shown).
The long telomeric end of DNA extracted from WJ-MSCs at all examined passages also confirms that these cells preserve their capability to undergo a high number of cellular divisions up to the 12th passage (data not shown) [ 15].
Further investigation revealed that many apps did not do enough to secure the passage of data from users back to central servers.
The estimate of the selection rate constant from the serial-passage data is quite similar to the result of the single-passage experiment (w = 1.53).
Transcripts emanating from this gene were not detected in both passages (data not shown), again indicating the repressed chromatin state is indeed preserved in senescing cells.
Similar results were obtained from MMTV-K-Ras tumors cultured as described above, whereby pStat3 and IL-6 levels were markedly decreased upon two passages (data not shown).
These features persisted after subsequent passages (data not shown).
Expression raw data from passage control cells were used for other exposure studies.
However, because of the effects of the passage of time, only data from the short occlusion period offer a pure measure of temporal orienting.
We do not presently have CGH or SNP array data from earlier passages or from other laboratories.
Five serial passages were performed, and the data from the two experiments were combined for analysis.
