Abstract:

BACKGROUND: In the repair of urinary tract defects, we have been actively trying to construct the urinary tract substitutes with normal physiological function through combining ideal seed cells and proper scaffold materials by tissue engineering method.
OBJECTIVE: To investigate the biocompatibility of bone marrow mesenchymal stem cells with rabbit bladder acellular matrix scaffold.
METHODS: Rabbit bone marrow mesenchymal stem cells were isolated and cultured using density gradient centrifugation method. Passage 3 rabbit bone marrow mesenchymal stem cells were cultured on the rabbit bladder acellular matrix. The cells were counted every day for 12 days, to drawn a cell growth curve. Bone marrow mesenchymal stem cells cultured alone were used as control group.
RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cells were successfully seeded onto the bladder acellular matrix. Under the inverted microscope, the cells grew out of the bladder acellular matrix, and a great amount of long spindle-shaped cells were found around the bladder acellular matrix. With 5 days of inoculation, the cells in the two groups grew gently; at 6-9 days, the cell growth curve gradually became steeper, and the cell division and growth were increased exponentially; at 10-12 days, the cells recovered to a gentle state. Cell growth curves in the two groups were basically coincident, suggesting that rabbit bone marrow mesenchymalstem cells have good biocompatibility with the bladder matrix.
