Staining for β-gal was performed at the vein-to-graft anastomosis removed from the BOEC and contralateral non-transplanted (control) specimens. In (A), L is the lumen, N is the neointima, M is a microvessel and A is adventitia. B is a high magnification of the adventitia. (A) Engraftment of Lac Z-positive labeled BOEC cells (blue) into the neointima (N). In (B), there is engraftment of Lac Z-positive cells into the microvessel (yellow arrows) in the adventitia. Lower panel shows quantitative analysis of the Lac Z-positive BOEC cells into the neointima and intima of both the transplanted and non-transplanted contralateral (control) vein-to-graft anastomosis. There was an increase in the engraftment of Lac Z-positive cells into the neointima of the control vein-to-graft anastomosis when compared to the BOEC.
