BACKGROUND: Experiments have confirmed that there are integrin receptors on bone marrow mesenchymal stem cells (BMSCs), but it is still uncertain whether angiogenin-1(Ang-1) can promote survival of BMSCs and protest against its apoptosis via integrins. OBJECTIVE: To investigate the effect of human recombinant angiopoietin-1 on adhesion, vigour, anti-apoptosis of rat BMSCs and its mechanism of signal transduction. DESIGN, TIME AND SETTING: The cytological in vitro controlled study was performed at the Opening Laboratory, Zhongshan Hospital Affiliated to Xiamen University from January to October 2008. MATERIALS: A total of 40 clean Sprague Dawley rats were supplied by Shanghai Experimental Animal Center, Chinese Academy of Sciences. Human Ang-1 (R&D) was used in this study. METHODS: Combining density gradient centrifugation and adherence separation was used to separate, cultivate and identify rat BMSCs. At the third to sixth passages, BMSCs were used for this study. Various matrix was used to coat 24-well culture plates for 1 hour. Following washing, monoplast suspension was added. Seven groups were set up. Group 1 served as control, BMSCs were coated with phosphate buffered saline containing 0.1% bovine serum albumin. BMSCs in the groups 2, 3 and 4 were incubated with vitronectin, fibronectin and Ang-1. BMSCs in the groups 5, 6 and 7 were firstly incubated in ethylenediaminetetraacetic acid, ?1 antibody and RGD antibody for 10 minutes, and then placed in a 24-well plate, and coated with Ang-1. MAIN OUTCOME MEASURES: Adhesion, trypan blue staining method, MTT test, Hoechst staining and Annexin V/PI were used to measure biological effects of Ang-1 on adherence, activity and anti-apoptosis of BMSCs. Combined with integrin antibody and signal transduction blocker, the expression of phosphoserine/threonine protein kinase B (pAkt), total Akt, Bcl-2 and ?-actin was examined by western blotting. RESULTS: Rat BMSCs were successfully isolated. The purity of BMSCs was 98.3% using flow cytometry. Cell adhesion assay shows Ang-1 promoted the adhesion of BMSCs at 1, 2 and 3 days compared with control group (P

Objective To analyze left ventricular (LV) global systolic function in patients with coronary artery disease(CAD) and their changes after percutaneous coronary intervention(PCI) using velocity vector imaging(VVI). Methods Eighteen healthy adults and twenty two patients with CAD were enrolled in this study. Two-dimensional dynamic images of standard apical four-chambers, two-chambers and parasternal short-axis views at the level of mitral valve and apex were obtained in VVI condition. All patients were examined 1 day before PCI, 1 week, 1 month and 3 months after PCI respectively. LV rotation degree, rotation velocity at baseline and apex were measured using the off-line syngo US workplace software and LV twist, torsion were calculated as global motion condition. Results LV ejection fraction(LVEF) and peak torsion at myocardial infarction group were lower than those at normal control and myocardial ischemia group. After PCI, LVEF were gradually improved in both myocardial infarction group and myocardial ischemia group,while changes of LV apex rotation degree and velocity, peak twist and peak torsion between two groups were opposite: those parameters of the former increased 1 week or 1 month after PCI but decreased 3 months after PCI,while those of the latter decreased 1 week after PCI but increased gradually 1 month and 3 months after PCI. Conclusions LV twist and torsion can be evaluated exactly by VVI.Compared with LVEF, LV twist and torsion can preferably reflect the different characteristic of LV global systolic function after coronary artery recanalization in myocardial infarction group and myocardial ischemia group.
