Abstract:

BACKGROUND: The correlation of zinc with Stro-1+ cells and bone morphogenetic protein 7 surrounding the prosthesis may affect the bone fusion and survival rate in hip prosthesis.

OBJECTIVE: To analyze the correlation of zinc content with Stro-1+ cells and bone morphogenetic protein 7 in proximal femur.
METHODS: Bone samples were obtained from the discarded metaphysis region of the proximal femur in 24 patients with primary total hip replacement. Bone marrow mesenchymal stem cells were cultured in vitro. At 14 days after culture, Stro-1+ cells in bone marrow mesenchymal stem cells were detected using flow cytometry. Bone morphogenetic protein 7 expression in cell supernatant was detected using enzyme-linked immunosorbent assay. Zinc content in supernatant was measured using radio-immunity assay.
RESULTS AND CONCLUSION: No significant difference in the zinc content was detected in different age groups and different gender groups. Zinc content was positively associated with Stro-1+ cells and bone morphogenetic protein 7 expression. The further study of the trace element zinc in proximal femur can predict and intervene the longevity of hip prosthesis.
