Abstract:
Objective:To evaluate the biocompatibility of insulin-like growth factor I (IGF-1) gene transfected bone marrow stem cells (MSCs) with ostrich true bone ceramic (OTBC). Methods:Rat MSCs were transfected with IGF-1 gene, and positive clones were selected by G418. The expression of IGF-1 protein in the MSCs was detected by immunocytochemical technique. The IGF-1 transfected MSCs were cultured with OTBC and the morphology of the cells was observed by scanning electronic microscope(SEM) at different time point. Results:Immunohistochemical staining suggested that the IGF-1 protein was expressed in the IGF-1 transfected MSCs. The cells adhered to OTBC and stretched well after 24 h of culture. The IGF-1 transfected MSCs proliferated on the surface of OTBC with culture time.Conclusion:The OTBC has a good biocompatibility with IGF-1 transfected MSCs.
