Fig. 3: Swim bladder patches harvested from aorta arterioplasty and IVC venoplasty at day 14.

a Photographs of hematoxylin & eosin staining of the swim bladder patches after arterioplasty or venoplasty, day 14. First row, low power photographs, scale bar, 1 mm; second to fourth rows, high-power photographs shows the neointima, cells infiltrated into the patch and the newly formed adventitia; scale bar, 100 μm; n = 3. b Bar graph showing the neointimal thickness in the arterioplasty (*p = 0.013) and venoplasty (*p = 0.0147) models, day 14; t-test; n = 3. c Bar graph showing the cells infiltrated into the patch in the arterioplasty (*p = 0.0001) and venoplasty (*p = 0.0008) models, day 14; t-test; n = 3. d Bar graph showing the adventitial thickness in the arterioplasty (*p = 0.0037) and venoplasty (*p = 0.0059) models, day 14; t-test; n = 3. Data are expressed as mean ± s.e.m.
