Figure 4. Enlarged cells elicited by functional knockdown of lin19 exhibit increased nuclear BrdU staining.

(A,B) PxnGal4>w ¹¹¹⁸ wild-type animals were fed BrdU during larval stages resulting in slight incorporation into the DNA as visualized by anti-BrdU and DAPI staining. (C,D) pxnGal4>lin19 RNAi ^HM05197 were fed BrdU during laval stages resulting in a distinct nuclear BrdU staining in the nucleus when observed with DAPI staining. Scale bar = 20 μm.
