BACKGROUND:Urothelial cells are important seeding cells for urinary tissue engineering, but they are difficult to proliferate in vitro. Several studies have shown that bone marrow mesenchymal stem cells can differentiate into urothelial cells, but how these cells functions in vivo in epithelium generation after implantation, and the application of these cells in tissue engineering, are rarely studied. OBJECTIVE:To explore the isolation and proliferation of rabbit bone marrow mesenchymal stem cells that are induced into urothelial cells in combination with rabbit bladder acellular matrix to construct tissue-engineered grafts, and to assess the effect of the induced cells as seeding cells. METHODS:Twelve 8-week-old male New Zealand white rabbits were chosen to obtain bone marrow samples through tibia puncture, and to isolate bone marrow mesenchymal stem cells by density gradient centrifugation. Then the fourth or fifth generation of bone marrow mesenchymal stem cells were cultured in conditioned medium for 2 weeks, and then identified by PCR and immunofluorescence. After that, the induced cells were seeded on rabbit bladder acellular matrix to construct tissue-engineered grafts for bladder repairing. Another 12 rabbits served as control group, and urothelial cells combined with bladder acellular matrix was used for bladder repairing. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cells were successful y cultured and proliferated in vitro. After induction, PCR detection suggested that stem cellmarker (CD44) expression decreased, and epithelial cellmarker (UP1a) expression increased in the induced cells. Immunofluorescence staining demonstrated that the induced cells rather than bone marrow mesenchymal stem cells were positive for specific urothelial marker, UP1a. A stable continuous epithelial layer was observed on tissue-engineered grafts constructed by induced cells after 2 weeks, similar to the grafts built by urothelial cells. Induced bone marrow mesenchymal stem cells can differentiate into urothelial cells that can be used as seeding cells for urinary tissue engineering, which may be another choice out of urothelial cells.

Objective To study the correlation between storage time and the content of 5-hydroxymethylfurfural (5-HMF) in Corni Fructus because of the color change caused by storage time. Methods Corni Fructus samples of different storage time with 0, 1, 2, 3, and 4 years were collected. The contents of 5-HMF were determined by HPLC. Results The HPLC determination method of 5-HMF in Corni Fructus was established. The contents of 5-HMF varied from undetected value to 0.292 8%, with the increase of storage time of 0, 1, 2, 3, and 4 years and the color gradually deepened from red, dark red, reddish brown to brown. The contents of 5-HMF in black wine-prepared Corni Fructus were 0.954 4%-1.837%. Conclusion The browning of Corni Fructus is related to the production of 5-HMF. With the extension of storage time of Corni Fructus, the color gradually deepens and the content of 5-HMF increase significantly. The storage time of Corni Fructus can be suggested to be one year.

BACKGROUND:The main way for long-segmental ureteral reconstruction may cause a lot of traumas and complications. Therefore, to seek a new repair method is urgent. OBJECTIVE:To investigate the feasibility of a tissue-engineered tubular graft for ureteral reconstruction. METHODS:Bone marrow mesenchymal stem cels and smooth muscle cels of rabbits were seeded into the two surfaces of bladder acelular matrix and cultivated for 7 days. Then the graft was used to prepare a 4-cm long tissue-engineered tubular graft, which was regarded as experimental group. Smooth muscle cels seeded onto the bladder acelular matrix was used to construct the tissue-engineered tubular graft as control group. Twenty-five New Zealand rabbits were randomly divided into experimental group (n=20) and control group (n=5), and two kinds of tubular grafts covered with omentum were implanted into the two groups, respectively, for repair of ureteral defects. Hematoxylin-eosin staining and immunohistochemical detection were performed at 2, 4, 8 weeks after implantation. RESULTS AND CONCLUSION:In the experimental group, hematoxylin-eosin staining showed epithelial coverage and muscle fibers on the lumen of tissue-engineered tubular grafts at 8 weeks after implantation; immunohistochemistry showed that anti-AE1/AE3 antibody and anti-uroplakinⅢa antibody were positive, confirming that there were mature epithelial cels on the lumen of tissue-engineered tubular grafts. In the control group, five rabbits were dead within 2 weeks after removal of ureteral scaffold, and autopsy showed scar formation inside the graft and severe hydronephrosis. These results demonstrate that it is feasible to construct the tissue-engineered tubular graft using bone marrow mesenchymal stem cels and smooth muscle cels into the bladder acelular matrix for ureteral reconstruction. Bone marrow mesenchymal stem cels can potentialy promote urothelial regeneration.
