The nonlinear mapping of BrdU intensity to the number of divisions during uptake and chase are summarized in Table 1, whose values are computed from Figure 6. Figure 6 depicts the average real-valued labeling percentage of a single cell based on up to 4 uptake divisions, and the decrease in label corresponding to each of the 1 to 4 uptake divisions.
3 4 This deterministic, cell based model integrates data from many sources on patient numbers, treatment uptake, treatment effectiveness, risk factor trends, and consequent mortality effects.
To permit more quantitative examination of lysis rates, we have developed a mathematical model for osmotic fragility of infected cells based on diffusional uptake via PESAC and the two-compartment geometry of infected RBCs.
There was also relatively little evidence of cell necrosis (<10% of cells) based on PI uptake, lack of DNA fragmentation, delayed externalisation of phosphatidylserine, and absence of processing of PARP.
This observation allowed us to develop an additional uptake assay for live cells based upon particle labeling by fluorescent dextran.
Dead cells were excluded based on propidium iodide uptake.
Though Fc-modified PEG-PLGA NPs exhibited a better Caco-2 cells uptake based on our data, which cell uptake mechanism is not clear, therefore, we would do more research about the cell uptake mechanism, e.g., Transport through cell monolayers study.
However, for studies on trans-differentiation, such as mesenchymal or hematopoetic stem cells differentiating to cells of other tissue like neurons or epithelial cells, interpretations based on the uptake of the label can be misleading especially since a very low percentage of cells are thought to change lineages and this may well be from the macrophage uptake of labels [45] [46].
C-MET and not FDG was found to be a significant prognostic factor for GBM based on uptake in proliferative cells (Kim et al, 2005).
Neutral red uptake assay was performed to determine the cell viability based on an established protocol [ 22].
