(A) The population of integrin α4 ＋ ASCs were about 5.11% and 70.7% in the pre- and postsorted ASCs, respectively. (B) Immunofluorescent staining revealed integrin α4 were robustly expressed in integrin α4 ＋ ASCs subpopulation. (C) Western blotting showed that the ex- pression of integrin α4 with 135 kDa was obviously more in integrin α4 ＋

Identification of Integrin α4 ＋/green fluorescent protein＋ (GFP＋) adipose-derived stem cells (ASCs) and incorporation of injected ASCs into the vasculature by immunofluorescent staining in infarcted myocardium 4 weeks posttransplantation. (A) Immunofluorescent staining was performed for GFP (green) and integrin α4 (red), and nuclei were stained with 4’,6-diamidino-2-phenylindole (DAPI, blue), co-localized expression of integrin α4 and GFP were detected in the hearts receiving integrin α4 ＋ ASCs subpopulation, and integrin α4 ＋ ASCs sub- population showed much higher engraftment than unfractionated ASCs. (B) Immunofluorescent staining was conducted for GFP (green) and von Willebrand Factor (vWF, red), and nuclei were stained with DAPI (blue), GFP-positive ASCs directly incorporated into vasculature.

Figure Lengend Snippet: Fig. 5. Integrin α4 ＋ adipose-derived stem cells (ASCs) subpopu- lation more robustly migrated and engrafted into the infartced my- ocardium after cell transplantation. (A) Four weeks posttranspla- ntation, green fluorescent protein-positive ASCs were more fre- quently detected in the hearts receiving integrin α4 ＋ ASCs sub- population than in the hearts undergoing unfractionated ASCs treatment. (B) The high reproducibility of the standard curve of re- al-time PCR. Serial dilution (10−2∼10−8) of DNA was made 7 times to construct the standard curve. Each pink circle corresponded to one dilution in one experiment. The blue solid line represented the regression analysis. (C) Four weeks after cell transplantation, in- tegrin α4 ＋ ASCs subpopulation treated rats showed the signifi- cantly greater ASC numbers per heart as compared to unfractio- nated ASCs treated rats. *p＜0.05 vs. unfractionated ASCs.

Figure Lengend Snippet: Fig. 6. Integrin α4 + adipose-derived stem cells (ASCs) subpopulation more effectively reduced infarct size post-implantation in vivo. (A) Representative tomographic histograms of the 18F-fluorodeoxyglucose (FDG) positron emission tomography images at 4 weeks posttrans- plantation. Yellow colors were indicative of higher tracer uptake, while blue colors stood for lower tracer uptake. (B) Four weeks after transplantation, unfractionated ASCs transplantation markedly elevated the 18F-FDG uptake in apical-septal, apical-anterior, and apex seg- ments as compared with phosphate-buffered saline (PBS) control. Of importance, integrin α4 + ASCs subpopulation implantation further increased the 18F-FDG uptake in apical-septal, apical-inferior, and apex segments compared with unfractionated ASCs injection. (C) Representative transverse, coronal, and sagittal myocardial 18F-FDG images at 4 weeks after cell transplantation. The infarcted area can be visually detected as an area of low glucose metabolism. (D) Four weeks after transplantation, integrin α4 + ASCs subpopulation markedly reduced infarct size as compared to unfractionated ASCs and PBS control. (E) Integrin α4 + ASCs subpopulation significantly increased global 18F-FDG uptake compared with unfractionated ASCs and PBS control. *p＜0.05 vs. unfractionated ASCs. #p＜0.05 vs. PBS.
