FIG. 7.

Analysis of the biopolymer patches explanted after 3 months. All biopolymers are evenly lined with endothelial (b, g, l) and smooth muscle cells (c, h, m). PDO has totally disappeared and is replaced by a neotissue similar to the native IVC (a–e). PU is encapsulated in a granulomatous inflammatory reaction (f, i, j). PHBVV starts to be degraded (k, n, o). DAPI staining again shows a greater cellularization of the PDO and PHBVV patches compared with PU (b, c, g, h, l, m). Scale bar: 50 μm.
