ABSTRACT
Objective To confirm that rat bone marrow mesenchymal stem cells (MSC) transfected with nerve growth factor (NGF) gene in the bladder tissue of diabetic rats bladder tissues can survive and stably express NGF. Methods A diabetic rat model was constructed. The BrdU-labelled MSC transfected with NGF gene were transplanted into the diabetic rats bladder tissues. BrdUlabelled immunohistochemistry was used to observe the growth of MSC transfected with NGF gene in the diabetic rats bladder tissues. The expression of NGF mRNA and protein were checked by RT-PCR and ELISA. Results A diabetic rat model was successfully built by a single intraperitoneal injectionof STZ. The blood glucose was still high after 8 weeks. NGF gene modified MSC could be detected in the bladder of diabetic rats by BrdU-labelled immunohistochemistry. The concentration of NGF in the control group, disease group and treatment group were ( 114 ± 3), ( 70 ± 2), ( 110 ± 2) pg/ml by ELISA and mRNA quantity by RT-PCR were 0. 183±0. 004, 0. 032±0. 139, 0. 130±0. 165, respectively. Compared with the control group, the expression of NGF gene was decreased (P<0. 05) in the incidence group. The expression of NGF gene was increased (P<0. 05) in the treatment group compared with the disease group. Conclusions The NGF gene-modified MSC could survive in diabetic rats bladder tissues. The NGF gene in MSC could stably express in diabetic rats bladder tissues.
