[Effect of fatty acids from plastrum testudinis on proliferation of rat bone mesenchymal stem cell].

To investigate the components in Plastrum Testudinis which have effects on the proliferation of rat bone marrow mesenchymal stem cells( bMMSCs), the active parts of plastrum testudinis which can promote proliferation of rat mesenchymal stem cells were extracted by petroleum aether. The activities of inducing the proliferation of bMMSCs were studied by MTT assay and flow cytometry. The chemical components of extraction were analyzed by GC-MS. The...
