Growth analysis of monotypic 3D-microtissues with constitutive lentiviral-RFP expression. a Example of RFP detection for breast cancer 3D-microtissue spheroids generated from T47D-RFP, MDA-MB-361-RFP and MDA-MB-231-RFP cells (9 days after treatment), b RFP plot quantification of MDA-MB-361 and T47D spheroid growth delay after 2 Gy irradiation at indicated time points. Data are averages ± SD (n = 4). MDA-MB-231 were not quantified using RFP area (μm2) settings, as they were not forming consistent spheroid structures during 13 days of analyses
