BRCA1 and cancer: The results show that the CM of ADSCs result in a dose-dependent stimulation of the proliferation of the cancer cell lines and that, in case of the Fat3A CM, this effect is more pronounced for the nonmutated cell lines MDA-MB-231 and T47D versus the BRCA1/2-mutated cell lines MDA-MB-436 and HCC1937, respectively (Fig. 1).
