Abstract：BACKGROUND:Bone marrow mesenchymal stem cel s have been shown to be differentiated into periodontal ligament fibroblasts when co-cultured with periodontal ligament cel s. Existing studies have shown that estrogen has the ability to influence bone marrow regeneration. OBJECTIVE:To investigate the effects of estrogen on osteogenesis and fibroblast-related factors alkaline phosphatase, type I and III col agen in bone marrow mesenchymal stem cel s. METHODS:Bone marrow mesenchymal stem cel s isolated from Beagle dogs were treated with estrogen. Osteogenesis and fibroblast-related mRNA and protein expression of bone marrow mesenchymal stem cel s was determined by RT-PCR and western blot assay, respectively. RESULTS AND CONCLUSION:mRNA and protein expression of type I and III col agen in bone marrow mesenchymal stem cel s was upregulated fol owing estrogen treatment;especial y, in contrast with type III col agen, the changes of type I col agen were more obvious. Estrogen did not influence mRNA and protein expression of alkaline phosphatase. These findings suggest that estrogen promotes the differentiation of bone marrow mesenchymal stem cel s into fibroblasts, whereas does not impact the genes involved in parodontium mineralization.
