Immunofluorescence expression of mouse-specific PECAM and human- specific vWF in thawed-ungrafted controls and implant groups. Results are represented as mean+SD. The x-axis represents the five experimental and control groups. The y-axis represents the level of fluorescence marker expression. (A) Peripheral mouse-specific PECAM and human-specific vWF expression in thawed-ungrafted controls and grafts. Levels were graded according to the intensity of fluorescence marker expression as in Figures 5 and 6. *Significantly higher than group B (P = 0.038). (B) Diffuse mouse specific PECAM and human specific vWF expression in thawed-ungrafted controls and implanted groups. Levels were graded according to the intensity of fluorescence marker expression as in Figures 5 and 6. *Significantly higher than groups B and C (P < 0.001 for both comparisons). **Significantly higher than groups B and C (P < 0.001, P = 0.002, respectively).
