Hello. This image is taken from la7 cancer stem cells. It seems that the cells that have a purple halo and seen shiner than other cells have a high resistance to starvation conditions. What kind of cells do you think these are and what is the reason for their resistance?
The cells you've described with a purple halo and shinier appearance in the LA7 CSCs culture, which demonstrate a high resistance to starvation, could be presumed to be a subpopulation within the cancer stem cells known for their resilience in adverse conditions. The existence of such cells that appear distinct in terms of color and brightness could indicate a subset of cells with certain biological properties that confer this resistance.
Without a detailed analysis through biochemical and genetic investigations, it's hard to determine the exact identity of these cells.
