The figure shows the fibrosis analysis. Top panel shows images of diaphragm, quadriceps and tibialis anterior sections from mice stained with Picro Sirius Red, which reveal collagen deposition as an indicator of fibrosis. Bottom panel shows violin plots representing the quantification of the percentage area of fibrosis in the diaphragm, quadriceps or tibialis anterior of wild-type, heterozygous and homozygous mice aged 2, 6 or 12 months.
Arístides López-Márquez, Cecilia Jiménez-Mallebrera & co used CRISPR/Cas9 to generate the first #MouseModel of a pathogenic variant that involves glycine substitutions in the triple helical domain of collagen VI alpha chains and leads to congenital #MuscleDisease.

Multipanel figure showing pathological changes in the brains and the peripheral organs of the investigated mouse models. Panel A: Images of the brains obtained from C57BL/6J mice not infected with JEV (Control), C57BL/6J, NCG and NCG-hSTAT2+/+ mice showing retention of Evans Blue. Panel B: Images, showing histopathological changes of the hippocampal area in the brains of mice as described in panel A. Panel C: a graph shoeing quantification of neuronal cell density in the hippocampus of the mice as described in panel B. Panel D: Images showing immunofluorescence staining of neuronal cells in the dentate gyrus region. Panel E: Histological images of liver and spleen tissues in mice, showing pathological changes in these peripheral organs.

Immunohistochemical detection of GM2 ganglioside in dKO, KIKO and CON brains. Sections were selected from similar areas of the brain for matched pairs. Sections for each matched pair were stained together and photographed at 63× using a Zeiss Axioimager equipped with ZEN software. Many images are taken from within the same field of view as the 20× images shown in Fig. S6A. Specifically, data in Fig. 6, panels E,F,G,I,J,N, and O are also shown in Fig. S6A, panels A,B,C,I,J,N, and O respectively. The presence of a red-brown staining signal for GM2 ganglioside was present in CON brains but much more broadly and abundantly present in the sections from the dKO and KIKO brains. Arrows indicate cells that have low levels of GM2 in CON (A,C,E,F,I,K,M,O), compared to the higher levels of GM2 present in vacuolated cells (B,D,F,H,J,L,N,P). Arrows in panels A-D identify Purkinje cells. Scale bars: 20 µM. These images are representative of those from three different pairs of animals.
