Dr Hazekamp: My other question is, you showed us these histology slides of the explanted homograft, but can you explain a little bit more, go a little bit more into detail about what cells did you see and how they were aligned? For example, did you see a true endothelial lining on this homograft and was it uniformly covering the homograft, and the myofibroblasts, which I think you saw them because you wrote it in the paper, were they scattered or were they in a uniform way introducing themselves in these homografts?
