Finally, when ductal labeling was carried out in 90% Ppx mice, the preliminary data suggested that no new islets were generated from the duct. Therefore, the mechanism for islet regeneration was different from islet development in the embryo.

Compared with PPX, the sulfonated PPX ( PPX-SO_3Na) has lower water contact angle and better hydrophilicity, which is useful for biological materials. The Advance of Polysaccharide Biomedical Materials-Chitin and Chitosan

与PPX相比，表面磺化改性PPX（PPX-SO3Na）的接触角变小，亲水性增加，更有利于作为生物医用材料。多糖类生物医用材料&甲壳素和壳聚糖的研究及应用

Therefore, PDL was a better model to study pancreas regeneration as compared to Ppx and STZ.

因此，PDL较Ppx和STZ是一个更为理想的胰腺再生模型。
