- Abstract: Objective: To explore the effects of the microenvironment of rabbit bladder acellular matrix graft (BAMG) on proliferation, cell surface markers, and molecular protein level of human bone marrow mesenchymal stem cells (hBMSCs). Methods: We prepared BAMG immersion fluid medium and detected its effect on the proliferation of hBMSCs by MTT method. The expressions of CD44, CD45, CD73 and PDGFRβ were detected by flow cytometry. The expressions of PPAR, OCN and α-SMA were detected by RT-PCR, and the expression of OCT was detected by Western blot. Results: hBMSCs had good compatibility with BAMG. The MTT method showed that BAMG and BAMG immersion medium did not affect the proliferation capacity of hBMSCs. The surface of hBMSCs cells cultured with immersion fluid still expressed CD44, CD73 and PDGFRβ, but not CD45. RT-PCR showed that OCN, PPAR, and α-SMA were all expressed. Western blot test also showed the positive expression of OCT-4. Conclusion: hBMSCs can still keep their original biological characteristics in the microenvironment of rabbit BAMG. It can be the seed cells and combined substrate materials for urinary system tissue engineering.
