Although the mechanisms that alter the bioenergetic metabolism in cancer cells are still not fully understood, it is generally postulated that increased glycolysis offers cancer cells an advantage to better proliferate, survive and become invasive in the tumor microenvironment [ 4, 7- 10].
The PLLA nanofibres displayed a significantly better proliferation rate, and enabled endothelial cells to proliferate in the monolayer.
It has been demonstrated that a small subset of cancer cells with stem cell properties, referred to as 'cancer stem cells' (CSCs), survive intensive anticancer therapies better than proliferating progenitor cells or differentiated tumour cells (Dean et al, 2005).
The smaller pores in the matrix allowed cells to spread better and proliferate faster, while cells in the larger pores tended to form large aggregates and had lower proliferation rate.
In fact, CD15-positive cells, similar to CD133-positive cells, survive better and proliferate faster as compared with their negative counterparts (Supplementary Figure 3), indicating its potential to complement some part of CD133 function.
Moreover, unlike fibroblasts, which proliferate better in 3% oxygen [ 27], keratinocytes proliferate better in 20% oxygen [ 57].
The selective importance of heme in tumor cell proliferation and function is also consistent with the previous observation that NSCLC cells require serum (containing heme) for maintenance and proliferation, whereas the normal lung cells survive and proliferate better with growth factors in the absence of serum [148, 149].
He also plans to see if human heart muscle cells grown in a laboratory dish proliferate better if the Hippo pathway is disrupted.
New services would proliferate; better service would ensue.
But they whittled that down to an app as smart TVs and better Android devices proliferated.
