Figure 2. Architecture of ascending thoracic aortas.
In adult Fibulin-4+/R and Fibulin-4R/R aortas there is an increase in aortic wall thickness (A–C), glycosaminoglycan depositions (blue areas) (D–F), elastic fiber fragmentation (G–I) and loss of smooth muscle cells in the media (J–L), also quantified (M).
