Spaceflight Affects Postnatal Development of the Aortic Wall in Rats
Figure 7
Area of the smooth muscle, elastin, and collagen fibers (a) in the longitudinal histological sections and number of nuclei of the smooth muscle cells (b) in the circumferential histological sections excised from the proximal thoracic aorta in the FLT, AGC, and VIV group rats. Values are mean ± SE. . . . Area of each component was measured in three given microscopic fields for one histological section stained with EVG with an image analysis system and then averaged within each group. The number of nuclei was measured in three given microscopic fields for one section stained with HE with an image analysis system and then averaged within each rat group.
