Article Title: Effects of CXCR4 Gene Transfer on Cardiac Function After Ischemia-Reperfusion Injury

doi: 10.2353/ajpath.2010.090451

Figure Lengend Snippet: CXCL12 is upregulated in ischemic myocardium of CXCR4-overexpressed rat. A: CXCL12 protein expression was assessed in hearts injected with either CXCR4 or β-gal and/or control (saline-injected; with IR) by immunofluorescence staining. Frozen sections were fixed and stained with anti-CXCL12 (green) and anti–α actinin (red). Primary Abs visualized with FITC or Texas Red conjugate. Nuclei were stained with DAPI. Images are taken with confocal microscopy. B: Protein lysates were prepared from rats’ hearts one week after CXCR4 gene transfer followed by 30 minutes LAD ligation and 24 hours reperfusion. The ischemic and remote tissues were lysed and analyzed by Western blot. Representative gel of three independent experiments is shown. C: CXCL12 mRNA levels were determined by quantitative real-time PCR (QRT-PCR) using a QuantiTect SYBR Green RT-PCR Kit and using specific primers for CXCL12 and 18S. Primers were designed to generate short amplification products. Densitometric analysis of data from three different experiments is shown. *P < 0.05.

Article Snippet: The following antibodies were used: (1) rabbit anti-mouse/rat CXCL12 (eBiosciences; San Diego, CA); (2) goat anti-rat CXCR4 antibody (Torrey Pines Biolabs; East Orange, NJ); (3) goat anti-mouse/rat TNF- α, (R&D), (4) mouse anti-rat leukocyte antibody (BD Pharmingen; Franklin Lakes, NJ); and (5) mouse anti- rat macrophage marker (VP-M640, Vector Laboratories; Burlingame, CA) Sections from the hearts were fixed and blocked with the normal serum and incubated with primary antibody for 2 hours at room temperature.

Blood collection and bladder excision were performed 24 h after intravesical substance P (SP). V, vehicle. Plasma HMGB1 levels were determined by ELISA, and protein levels were quantified by Western blotting. V, vehicle.

Article Title: High-mobility group box 1 fragment suppresses adverse post-infarction remodeling by recruiting PDGFRα-positive bone marrow cells

doi: 10.1371/journal.pone.0230392

Figure Lengend Snippet: The second examination was performed using the same MI rats prior to HMGB1 treatment to assess the expression of SDF1, a representative homing factor of MSCs. A: Study protocol of second examination. B: Histological analysis revealed SDF1 expression along the peri-infarction area in MI model and normal rats (40×, scale bar = 200 μm). C: RT-PCR analysis indicated that SDF1 expression increased significantly in MI rats (n = 6) compared with normal rats (n = 10). P -values were calculated using the Welch’s t-test. P < 0.05*, P < 0.01**.

Article Snippet: In the second examination, the frozen sections in MI and normal rats were stained with rabbit anti-SDF1 polyclonal antibody (1:50; Abcam, Cambridge, UK), and were evaluated using the confocal laser microscopy.

Figure Lengend Snippet: Intravital imaging analysis was performed using the GFP-BMT rat MI model to visualize HMGB1-induced GFP + -cells mobilization to the damaged heart tissue in real time. A: Details of the study protocol using intravital imaging. B: Histological findings in GFP-BMT rat MI model 12 h after HMGB1 treatment. 1, 2) More GFP + /PDGFRα + cells were visualized in the HMGB1 group compared with the control (100×, 600×; scale bar = 100, 200 μm, respectively). C: In the HMGB1 group, GFP + -cells were recruited along the peri-infarction area with SDF1 over-expression (100×, scale bar = 200 μm). Conversely, the recruitment of GFP + -cells was not enhanced at the remote area, where significant expression of SDF1 was not observed. P -values were calculated using the Welch’s t-test. P < 0.01**.

doi: 10.1371/journal.pone.0230392

Figure Lengend Snippet: Systemic administration of HMGB1 fragment can mobilize BM mesenchymal cells, including BM-MSCs, to blood circulation. Consequently, these BM-derived mesenchymal cells accumulate in the damaged myocardium through the SDF1/CXCR4 signaling complex, leading to functional recovery by paracrine activity of the BM-MSCs or to differentiation of some vascular constituent cells.
