These high-population cells appear in clusters throughout the lattice since nearest neighbors exchange population.
Figure 4G shows that DS/Cu induces the expression of p21 and p53 protein but has no effect on CDK2, Cyclin D1 and E. The MDA-MB-231PAC10 cell line is composed of high population of cells expressing stem cell markers that may play a key role in the pan-resistance.
Cancer therapy has been most successful against aggressive tumors characterized by a high population of cells in active cell growth (high-growth fraction), although acquired impairment of DNA-damage repair mechanisms may underlie the chemotherapy sensitivity of the most curable cancers [1].
However, the cell pools displayed an inhomogeneous expression pattern at non-saturating levels of 0.1 2.0 µg/mL: while cells from the 'low' population provided a bimodal distribution, the 'high' population cells remained fully induced at inducer levels of 0.5 µg/mL and above (Fig. 5A).
Therefore, these benefits should enable BelloCell to be adopted as a simple system for high population density cell culture and virus production.
Interestingly, the expression distribution at the entry of stationary phase in M9-amino acids is trimodal: the majority of cells exhibits no expression, while the cells that do induce the colicin operon can be divided into a low-induction population (likely cells that have just initiated expression) and a high-induction population (cells that have reached the maximum induction level).
Although all of SP cells are not cancer stem cells, SP cells contain high population of cancer stem cells.
Because M. xanthus is a predatory bacterium whose growth is facilitated by high population density, the cells have evolved to sporulate in mounds to aid in dispersal of groups of cells [ 5, 6].
Comparing MCF-7 and Cal51 cells, both MCF-7/A02 and CALDOX cell lines were composed of a much higher population of cells exhibiting ALDH activity, and the ALDH activity in these MDR cell lines were remarkably inhibited after exposure to BKM120 in the doses lower than IC50.
TUNEL staining performed on sections of the tumor also confirmed that EGFR-targeted nanoparticle treated tumor section show highest population of cells undergoing apoptosis (brown TUNEL positive cells) compared to those treated with SH-Gel and SH-Gel-PEG.
Passaged meniscus cells contain a high population of fibroblast-like cells; the observed decrease in collagen I expression was therefore not surprising [ 27].
