Islet at day 7 post-transplant. Arising from the vessels running along the outer surface of this large islet, many new vessels (arrows) are growing and penetrating from all directions towards the inner part of the endocrine parenchyma. Some vessels, lined by endothelial cells, are also visible in the islet parenchyma (arrowheads). Semithin section, methylene blue stain, 200×, scale bar = 100 µm.
