Fig. 5From: The optimal time to inject bone mesenchymal stem cells for fracture healing in a murine modelChanges in the gene expression levels of SDF-1, TGF-beta 1, and MCP-3 in callus of the fractured dogs. Stromal cell-derived factor 1 (SDF-1), transforming growth factor Ī²1 (TGF-Ī²1), and monocyte chemoattractant protein 3 (MCP-3) are important chemokines for BMSC migration. Quantitative RT-PCR analysis of mRNA levels was measured by q-RT-PCR from callus after fracture at days 0, 3, 7, 14, and 28 (*Pā<ā0.05 compared with day 3 and 2Ā weeks) (nā=ā3).
