Colony-forming efficiency assay of pooled adipose-derived stem cells (pADSCs) in comparison to MCF-7, MCF10A, and ZR-75-1 cells. ADSCs of 10 donors were pooled and, like ZR-75-1, MCF-7, and MCF10A cells, seeded 24 h before the IR procedure, where 0 Gy was defined as the control. The cells were stained by crystal violet to visualize formed colonies. The cell survival fractions (SF) of the different experimental approaches were normalized to those of unirradiated cells; n = 5 (MCF-7 cells and ZR-75-1 cells), n = 4 (pADSCs), or n = 3 (MCF10A cells) presented as mean ± standard deviation. Asterisks illustrate significance: ** p < 0.01; *** p < 0.002 (one sample t-test).
