Zhang Xin-ru, Lu Wen-long, Feng Chao, Lv Xiang-guo, Zhu Wei-dong . Constructing tissue-engineered bladder by vascular endothelial growth factor nanoparticle-bacterial cellulose composite scaffold with various kinds of cells[J]. Chinese Journal of Tissue Engineering Research, 2016, 20(21): 3088-3096.
尿动力学检查:在模型制备前,实验组和对照组的膀胱最大容积分别为(69.55±8.68) mL和(66.31± 6.32) mL,植入后3个月,两组的膀胱最大容积均有下降,分别为(58.75±3.14),(50.13±2.42) mL,对照组下降幅度高于实验组(P < 0.05)。在模型制备前,实验组和对照组的漏尿点压力分别为(3.45±0.78),(3.64± 0.52) kPa,植入后3个月的漏尿点压力分别为(3.15± 0.51),(2.67±0.60) kPa,对照组下降幅度高于实验组 (P < 0.05)。 在模型制备前,实验组和对照组的漏尿点压力分别为(3.45±0.78),(3.64±0.52)kPa,植入后3个月的漏尿点压力分别为(3.15±0.51),(2.67±0.60) kPa,对照组下降幅度高于实验组(P < 0.05)。 组织学检查:对照组膀胱替代组织表面未能构建出完整的上皮细层,其下方亦未能够证实有充分肌细胞的形成,同时采用CD31抗体的免疫组织化学染色中,仅见黏膜下方有少量微血管形成。实验组修复处膀胱组织的苏木精-伊红及免疫组织化学切片中可见到有完整上皮细胞层的形成,同时在使用α-SCA抗体的免疫组织化学切片中,可以见到黏膜下方有较多肌层形成,CD31检查可发现有较多量毛细血管形成,见图7。"
