This study investigated the effect of cilostazol on proangiogenesis functions in human early endothelial progenitor cells (EPCs) in vitro and the therapeutic implication of hybrid therapy with cilostazol and human early EPCs in vivo. Cilostazol significantly increased colony-forming units and enhanced differentiation of EPCs toward endothelial lineage. Treatments resulted in antiapoptotic effects and stimulated proliferation and migration and in vitro vascular tube formation through activation of stromal cell-derived factor-1 (SDF-1)/C-X-C chemokine receptor type 4 (CXCR4)/phosphatidylinositol-3 kinase (PI3K)/Akt signaling pathway...

OBJECTIVE Chronic subdural hematoma (CSDH) is prevalent in the aged population and is commonly treated with bur hole drainage. This treatment, however, can lead to various surgical complications. Atorvastatin may cure CSDH via its antiinflammatory and proangiogenesis effects, but not all patients treated with this medication can avoid surgery. The authors' aim was to investigate the effect of atorvastatin and identify characteristics of patients with CSDH sensitive to atorvastatin therapy. METHODS A prospective, placebo-controlled observational study was conducted in 80 patients with evidence of CSDH...

UNLABELLED: Effectively stimulating angiogenesis and avoiding wound infection are great challenges in wound care management. Designing new healing dressings with requisite angiogenic capacity and antibacterial performance is of particular significance. In order to achieve this aim, we prepared a copper (Cu)-containing bioactive glass nanocoating (40-50nm) with uniform nanostructure on natural eggshell membrane (Cu-BG/ESM) by the pulsed laser deposition (PLD) technique. The surface physicochemical properties including hydrophilicity and hardness of ESM were significantly improved after depositing Cu-BG nanocoatings...

UNLABELLED: Cell secretion is an important mechanism for stem cell-based therapeutic angiogenesis, along with cell differentiation to vascular endothelial cells or smooth muscle cells. Cell-released microvesicles (MVs) have been recently implicated to play an essential role in intercellular communication. The purpose of this study was to explore the potential effects of stem cell-released MVs in proangiogenic therapy. We observed for the first time that MVs were released from adipose-derived stem cells (ASCs) and were able to increase the migration and tube formation of human umbilical vein endothelial cells (HUVECs)...

Formononetin is an isoflavone that has been shown to display estrogenic properties and induce angiogenesis activities. However, the interrelationship between the estrogenic properties and angiogenesis activities of formononetin are not well defined. In the present study, docking and enzymatic assay demonstrated that formononetin displayed direct binding to the ligand-binding domain (LBD) of estrogen receptor alpha (ERα) with an agonistic property. Results from Human Umbilical Vein Endothelial Cells (HUVEC) by using real-time migration xCELLigence system, immunofluorescence and western blotting provided strong evidences of formononetin induced endothelial cell migration and dramatic actin cytoskeleton spatial modification through ERα-enhanced-ROCK-II/MMP2/9 signaling pathways...

Arachidonic acids are converted to eicosanoid mediators by different enzyme systems: cyclooxygenase, lipoxygenase, and cytochrome P450 (CYP) monooxygenase pathways (ω/ω-1-hydroxylases and epoxygenases). Of 57 putatively functional human CYPs, only about a dozen enzymes are responsible for xenobiotic metabolism. CYP2 family is the predominant epoxygenase isoform abundantly expressed in the endothelium, myocardium, and kidney in humans. Numerous studies have demonstrated the cardiovascular protective effects of CYP epoxygenases and eicosatrienoic acids ranging from vasodilation, antihypertensive, proangiogenesis, antiatherosclerosis, and cardiac protection...

S-propargyl-cysteine (SPRC), also named as ZYZ-802, is a structural analog of S-allylcysteine (SAC), the most abundant constituent of aged garlic extract. SPRC becomes a derivative of the amino acid cysteine, which contains sulfur atom, by changing allyl group in SAC to propargyl group in SPRC. Another analog of SPRC and SAC is S-propyl cysteine (SPC), which has propyl group instead in its cysteine structure. Drug formulation of SPRC has been investigated in the mixture of extenders, such as lactose, microcrystalline cellulose, and cross-linked povidone, showing good fluidity and scale-up production possibility...

Hydrogen sulfide (H2S), produced endogenously by the activation of two major H2S-generating enzymes (cystathionine β-synthase and cystathionine γ-lyase), plays important regulatory roles in different physiologic and pathologic conditions. The abnormal metabolism of H2S is associated with fibrosis pathogenesis, causing damage in structure and function of different organs. A number of in vivo and in vitro studies have shown that both endogenous H2S level and the expressions of H2S-generating enzymes in plasma and tissues are significantly downregulated during fibrosis...

The vascular endothelial growth factor (VEGF)-VEGF receptor (R) system is deeply involved in angiogenesis and lymphangiogenesis. VEGFR1/ Fms-like tyrosine kinase-1 (Flt-1) and VEGFR2 are significantly expressed in vascular endothelial cells, where they transfer proangiogenic signals. Particularly, VEGFR2 has strong tyrosine kinase activity; thus, the major and direct angiogenic signals are generated from VEGFR2. VEGFR3 is specifically expressed in lymphatic endothelial cells, generating the main signal for lymphangiogenesis...

Cardiovascular disease is the leading cause of death globally, and stem cell therapy remains one of the most promising strategies for regeneration or repair of the damaged heart. We report that human placenta-derived multipotent cells (hPDMCs) can modulate cardiac injury in small and large animal models of myocardial ischemia (MI) and elucidate the mechanisms involved. We found that hPDMCs can undergo in vitro cardiomyogenic differentiation when cocultured with mouse neonatal cardiomyocytes. Moreover, hPDMCs exert strong proangiogenic responses in vitro toward human endothelial cells mediated by secretion of hepatocyte growth factor, growth-regulated oncogene-α, and interleukin-8...

The liver has a remarkable capacity to regenerate after injury; yet, the role of macrophages (MF) in this process remains controversial mainly due to difficulties in distinguishing between different MF subsets. In this study, we used a murine model of acute liver injury induced by overdose of N-acetyl-p-aminophenol (APAP) and defined three distinct MF subsets that populate the liver following injury. Accordingly, resident Kupffer cells (KC) were significantly reduced upon APAP challenge and started recovering by self-renewal at resolution phase without contribution of circulating Ly6C(hi) monocytes...

Copper stimulation of angiogenesis at the organ system level is vascular endothelial growth factor (VEGF) dependent, but copper stimulation of vascular endothelial cell proliferation in cultures is VEGF independent. The present study was undertaken to use isolated rat aortic rings to understand the seemly controversial observations between in vivo and in vitro studies. The thoracic aorta was isolated from Sprague Dawley rats (8-10 weeks) and sectioned into 1.0-mm thick vascular rings for culturing. Copper sulfide at a final concentration of 5, 25, 50 or 100 μM was added to the cultures and maintained for 8 days...
