From: The application of tissue-engineered fish swim bladder vascular graft
a Photographs showing the swim bladder before and after decellularization, stained with hematoxylin & eosin, VVG, trichrome, α-actin, collagen-1, fibronectin, or vimentin; scale bar, 100 μm; n = 3. b Bar graph showing the cell number before and after decellularization, *p = 0.0031, t-test; n = 3. c SEM images of fresh, decellularized and rapamycin-coated patches (rapa-coating); scale bar, 200 μm; n = 3. d Water contact angles of fresh, decellularized and rapamycin-coated patches; the inset panels showing the photographs of the water contact angles; p < 0.0001, one-way ANOVA; *p < 0.0001, Tukey’s multiple comparisons test; n = 3. e Bar graph showing the burst test, *p = 0.0003, one-way ANOVA; d-TA, decellularized rat thoracic aorta; n = 4. f Bar graph showing the suture retention, *p = <0.0001, one-way ANOVA; d-TA, decellularized rat thoracic aorta; n = 4. Data are expressed as mean ± s.e.m.
