Engineered Hypopharynx from Coculture of Epithelial Cells and Fibroblasts Using Poly(ester urethane) as Substratum

<table>Hematoxylin and eosin (H&amp;E) staining. Scaffolds PEU (a) and PEU-SF (b) were implanted subcutaneously into Wistar rat back for 20 d (1), 40 d (2), and 100 d (3), respectively. The inserted images were of higher magnification. The arrow pointed out the growing tissue in scaffold. Scale bar 200 <i>μ</i>m.</table>
