Of interest, there was no growth disadvantage in cells irradiated with γ-rays, and these cells showed a rather slight delay in the onset of senescence; however, this delay was not statistically significant (see figure legend).
This tissue dependance has been suggested to result from a replicative disadvantage of cells harboring a high mutant load, thus promoting "mutation epuration" from fast regenerating tissues.
Again, we used the ΔNGFR surface marker to distinguish the transduced population from the untransduced in order to take into account the growth disadvantage of cells expressing p53-activating peptides.
We wanted to determine if the loss of the DNA and H3K9 methylation signal after 5 days could be caused by a selective growth disadvantage of cells after VEGF-A silencing.
One disadvantage with cell lines is that prolonged in vitro culturing may lead to changes in their genetic background or behavior, and there is also a risk that certain cells are selected based on their high proliferation capacity or whether they grow adherent or non-adherent [100].
Experiments to distinguish between these possibilities and to elucidate whether similar DC defects also further disadvantage T-cell responses to other intracellular infections in old organisms are currently under investigation.
Mechanism (ii) also leads to a potential disadvantage for OB cells in the presence of MM cells, whereas MM cells are unaffected by the presence of OB cells.
However, changes in δ may have a significant effect on the life history of the disease and associated progression time, as shown in Figure 2D: Increasing δ for fixed β – that is, increasing the disadvantage of OB cells in the presence of MM cells – leads to disease dynamics, in which considerable bone loss occurs without a significant increase in the MM population.
Table 3 provides representative verbatim quotes from individuals regarding the perceived advantages and disadvantages of cell phones.
Despite the disadvantages, cancer cell lines have been, and will continue to be, the model system of the cancer in vitro.
