Figure 2From: A new unique form of microRNA from human heart, microRNA-499c, promotes myofibril formation and rescues cardiac development in mutant axolotl embryosTropomysin expression in RNA-treated mutant axolotl hearts revealed by immunofluorescent staining with confocal microscopy. (A) Normal heart. (B) Mutant untreated heart. (C) Mutant heart treated with cloned RNA (clone #291) after 5 days of incubation in organ culture. Magnification is the same in all images.Back to article page
