Short-term characterization (7 days after grafting) of T and ET models. Immunofluorescence of human PECAM-1 (A–B), mouse PECAM-1 (C–D) and mouse red blood cells (E–F) for T (left column) and ET models (right column), at 7 days. Presence of mouse capillaries was similar in both models, but mouse red blood cells were located at the periphery of the T model. In the ET model, human capillaries and mouse red blood cells were present throughout the tube. Antibodies are illustrated in red and nuclei in blue. Scale bar: 50 μm.
