G Representative fluorescensce micrographs of GFP:sh-scramble (n=8) and GFP+ shLOXL1 (n=10) MM134 xenografted glands. ILC cells expressing viral transcripts are detected based on GFP expression (green); DAPI nuclear stain (blue). Asterics point to intraductal growth while arrow points to invasive tumor cells. Scale bars, 50 μm.
