We constructed a UC-VEGF-SMC three dimensional (3D) scaffold to explore its effect on blood vessel regeneration and bladder repair function in a rabbit model with bladder injury. Rabbit adipose tissue-derived stem cells (ADSCs) were cultured to construct pluripotent stem cell systems that can be induced to differentiate into urothelial cells (UCs) and smooth muscle cells (SMCs). Reverse transcriptase-polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), immunofluorescence, MTT assay and HE staining were used in our study. Rabbit models were divided into an experimental group, control group and sham group. The bladder histology, urodynamics, smooth muscle function, stent degradation rate, urothelial permeability and biomechanical determination of rabbits were detected after grafting the scaffold. Correct stem cells based on the ADSC surface marker and found that CD90 and CD105 were positive and that CD34 and CD45 were negative. RT-PCR showed that ADSC-iPS cells expressed the marker gene of embryonic stem cells (ESCs), which indicated that Sox2, Klf4, Oct4 and c-Myc were inserted into the iPS nucleus and that the ADSC-iPS system was constructed successfully. Immunofluorescence and MTT assays indicated that iPS differentiated into mature SMCs and UCs. ELISA and HEMC culturing methods revealed that vascular endothelia growth factor (VEGF) could promote the growth of HMECs. Rabbit bladder repair function (urodynamics, smooth muscle function, urothelial permeability and biomechanical determination) was stronger in the experimental group than in the control group. UC-VEGF-SMC 3D nano scaffold exhibits good repair function for bladder damage, which may helpful for treatment of damaged bladders.
