ppx

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.

将胰管标记运用于90%Ppx模型，初步的实验结果提示，再生模型中没有从胰管新生的胰岛，说明其再生机理和胚胎中胰岛的发育不一样。

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。
