When the particle-treated cells received repeated administration of the particles or recovery from frozen storage, even when the cells grew on the surface coated with the particles, they still maintain proliferative activity, suggesting that the 6MP-AuNPs-RDP should have the potential for application.
They further show that cardiomyocytes from fish and newt, which are known to maintain proliferative activity, maintain centrosome integrity, consistent with their model.
While all N-Ep and most T-Ep cultures have limited expansion (3 7 passages), some cases maintain proliferative activity for extended passages.
Although overexpression of Notch 1 mRNA or protein has not been found in ovarian tumours, our data point to a possible role of the Notch pathway in ovarian cancer formation: our transfection experiments indicate, that activation of the Notch pathway could contribute to the malignant phenotype by maintaining proliferative activity against growth control signals and by promoting cell survival.
We therefore evaluated the sensitivity of NG2-KO glioma cells to increased cell density in culture, and we observed that, like wild type cells, NG2-KO tumor cells bypassed cell-cell contact inhibition and maintained their proliferative activity, eventually forming three dimensional cell foci.
In keratinocytes, BNC maintains proliferative capacity and prevents their terminal differentiation [ 62].
After 5 and 6 days in vitro, untreated slices maintained a high proliferative activity.
As showed in Figure 2A, TGFαL3SEAD227A maintained 77.8% of the proliferative activity of rSEA.
These cells in culture exhibit proliferative activity, maintain typical mesenchymal markers, as well as differentiation potential [ 18].
