Fig. 5: Histological analysis of liver and heart following fetal scAAV9 delivery.

a Histological analysis of liver morphology by HE staining and hepatocytes functionality evaluated by PAS activity; Masson Trichrome (MT) analysis did not highlight fibrotic areas in scAAV9-GFP injected fetuses. b Histological analysis of myocardium morphology by HE staining did not reveal significant alterations or inflammatory infiltrations. MT analysis did not highlight fibrotic areas in scAAV9-GFP injected fetuses. Scalebar, 100 μm.
