We describe the experimental design protocol used to achieve the culture conditions necessary to obtain both high-cell-density and TAG accumulation; specifically, we describe the importance of the C/N ratio of the medium composition.
With primary PCa composed of a mixture of cells with high or low mitochondrial genome content, cells with high mitochondrial content may generate more hypoxia-induced changes that benefit the growth and maintenance of both groups under high cell density conditions, that is, the primary tumor site.
Finally, our data showing that TDZD-8 decreases the formation of neurospheres, both at low and high cell density, suggest that this drug could have an inhibitory effect on glioblastoma stem cells proliferation and self-renewal.
The production of PGA in bioreactor cultivations has been widely studied using both batch [ 20- 22] and high cell density fed-batch cultures [ 6, 23, 24].
This presumably indicates that the presence of both variants is necessary to achieve high cell density of adherent bacteria.
Furthermore, crvA is quorum regulated, and CrvA-dependent curvature increases at high cell density.
Both phenotypes suggest that downregulation of O1 antigen phage receptor occurs in response to autoinducers and thus at high cell density.
Muller, C., Laurent, G. & Ling, V. P-glycoprotein stability is affected by serum deprivation and high cell density in multidrug-resistant cells.
Romer, P. S. et al. Preculture of PBMCs at high cell density increases sensitivity of T-cell responses, revealing cytokine release by CD28 superagonist TGN1412.
