Description
An account of the resource
Drug-induced acute tubular necrosis is a primary cause of acute renal failure (ARF); it may result from the use of such agents as aminoglycosides, amphotericin B, and radilocontrast media. To reduce the risk of aminoglycoside toxicity, prescribe the shortest course possible, use once-daily dosing, monitor serum concentrations, and avoid using these agents altogether in patients with known risk factors. Radiocontrast media-associated ARF is most likely to occur with preexisting renal damage, especially in a patient with diabetes mellitus. Since sodium depletion is the most important risk factor for nephrotoxic injury with amphotericin B use, saline loading is recommended both before and during drug administration. Drug-induced acute interstitial nephritis, another important cause of ARF, has been associated with a number of antibiotics, especially penicillin and ampicillin; many patients recover with the removal of the offending agent.

RATIONALE: A well-developed coronary collateral circulation improves the morbidity and mortality of patients following an acute coronary occlusion. Although regenerative medicine has great potential in stimulating vascular growth in the heart, to date there have been mixed results, and the ideal cell type for this therapy has not been resolved. OBJECTIVE: To generate induced vascular progenitor cells (iVPCs) from endothelial cells, which can differentiate into vascular smooth muscle cells (VSMCs) or endothelial cells (ECs), and test their capability to stimulate coronary collateral growth. METHODS AND RESULTS: We reprogrammed rat ECs with the transcription factors Oct4, Klf4, Sox2, and c-Myc. A population of reprogrammed cells was derived that expressed pluripotent markers Oct4, SSEA-1, Rex1, and AP and hemangioblast markers CD133, Flk1, and c-kit. These cells were designated iVPCs because they remained committed to vascular lineage and could differentiate into vascular ECs and VSMCs in vitro. The iVPCs demonstrated better in vitro angiogenic potential (tube network on 2-dimensional culture, tube formation in growth factor reduced Matrigel) than native ECs. The risk of teratoma formation in iVPCs is also reduced in comparison with fully reprogrammed induced pluripotent stem cells (iPSCs). When iVPCs were implanted into myocardium, they engrafted into blood vessels and increased coronary collateral flow (microspheres) and improved cardiac function (echocardiography) better than iPSCs, mesenchymal stem cells, native ECs, and sham treatments. CONCLUSIONS: We conclude that iVPCs, generated by partially reprogramming ECs, are an ideal cell type for cell-based therapy designed to stimulate coronary collateral growth.

Description
An account of the resource
The possible means by which type I collagen may mediate mineralization in normal vertebrate bone, tendon, dentin and cementum as well as in pathological mineral formation are not fully understood. One consideration in this regard is that the structure of the protein is somehow important in binding calcium and phosphate ions in a stereochemical configuration conducive to nucleation of apatite crystals. In the present study, type I collagen, packed in a quarter-staggered arrangement in two dimensions and a quasi-hexagonal model of microfibrillar assembly in three dimensions, has been examined in terms of several of its charged amino acid residues. These included glutamic and aspartic acid, lysine, arginine, hydroxylysine and histidine, whose positions along the three alpha-chain axes of the collagen molecule were determined with respect to each other. It was found that the locations of these residues specified sites uniquely suited as potential apatite nucleation centers following binding of calcium and phosphate ions. From this analysis, it would appear that type I collagen provides a template of charged amino acid residues that dictates ion binding critical to subsequent nucleation events for mineral formation in vertebrate tissues.

Description
An account of the resource
Reactive oxygen species (ROS) are implicated in coronary collateral growth (CCG). We evaluated the requirement for ROS in human coronary artery endothelial cell (HCAEC) tube formation, CCG in vivo, and signaling (p38 MAP kinase) by which ROS may stimulate vascular growth. The flavin-containing oxidase inhibitor diphenyleneiodonium (DPI) or the superoxide dismutase inhibitor diethyldithiocarbamate (DETC) blocked vascular endothelial growth factor-induced HCAEC tube formation in Matrigel. We assessed the effect of DPI and DETC on CCG in a rat model of repetitive ischemia (RI) (40 s left anterior descending coronary artery occlusion every 20 min for 2 h 20 min, 3 times/day, 10 days). DPI or DETC was given intraperitoneally, or the NAD(P)H oxidase inhibitor apocynin was given in drinking water. Collateral-dependent flow (measured by using microspheres) was expressed as a ratio of normal and ischemic zone flows. In sham-operated rats, collateral flow in the ischemic zone was 18 +/- 6% of normal zone; in the RI group, collateral flow in the ischemic zone was 83 +/- 5% of normal zone. DPI prevented the increase in collateral flow after RI (25 +/- 4% of normal zone). Similar results were obtained with apocynin following RI (32 +/- 7% of that in the normal zone). DETC achieved similar results (collateral flow after RI was 21 +/- 2% of normal zone). DPI and DETC blocked RI-induced p38 MAP kinase activation in response to vascular endothelial growth factor and RI. These results demonstrate a requirement for optimal ROS concentration in HCAEC tube formation, CCG, and p38 MAP kinase activation. p38 MAP kinase inhibition prevented HCAEC tube formation and partially blocked RI-induced CCG (42 +/- 7% of normal zone flow), indicating that p38 MAP kinase is a critical signaling mediator of CCG.

Description
An account of the resource
Coronary collateral growth is a process involving coordination between growth factors expressed in response to ischemia and mechanical forces. Underlying this response is proliferation of vascular smooth muscle and endothelial cells, resulting in an enlargement in the caliber of arterial-arterial anastomoses, i.e., a collateral vessel, sometimes as much as an order of magnitude. An integral element of this cell proliferation is the process known as phenotypic switching in which cells of a particular phenotype, e.g., contractile vascular smooth muscle, must change their phenotype to proliferate. Phenotypic switching requires that protein synthesis occurs and different kinase signaling pathways become activated, necessitating energy to make the switch. Moreover, kinases, using ATP to phosphorylate their targets, have an energy requirement themselves. Mitochondria play a key role in the energy production that enables phenotypic switching, but under conditions where mitochondrial energy production is constrained, e.g., mitochondrial oxidative stress, this switch is impaired. In addition, we discuss the potential importance of uncoupling proteins as modulators of mitochondrial reactive oxygen species production and bioenergetics, as well as the role of AMP kinase as an energy sensor upstream of mammalian target of rapamycin, the master regulator of protein synthesis.

Description
An account of the resource
Vascular precursor cells include stem cells and progenitor cells giving rise to all mature cell types in the wall of blood vessels. When tissue injury occurs, local hypoxia and inflammation result in the generation of vasculogenic mediators which orchestrate migration of vascular precursor cells from their niche environment to the site of tissue injury. The intricate crosstalk among signaling pathways coordinates vascular precursor cell proliferation and differentiation during neovascularization. Establishment of normal blood perfusion plays an essential role in the effective repair of the injured tissue. In recent years, studies on molecular mechanisms underlying the regulation of vascular precursor cell function have achieved substantial progress, which promotes exploration of vascular precursor cell-based approaches to treat chronic wounds and ischemic diseases in vital organ systems. Verification of safety and establishment of specific guidelines for the clinical application of vascular precursor cell-based therapy remain major challenges in the field.

Description
An account of the resource
Ischemic heart disease is still the leading cause of death even with the advancement of pharmaceutical therapies and surgical procedures. Early vascularization in the ischemic heart is critical for a better outcome. Although stem cell therapy has great potential for cardiovascular regeneration, the ideal cell type and delivery method of cells have not been resolved. We tested a new approach of stem cell therapy by delivery of induced vascular progenitor cells (iVPCs) grown on polymer micro-bundle scaffolds in a rat model of myocardial infarction. iVPCs partially reprogrammed from vascular endothelial cells (ECs) had potent angiogenic potential and were able to simultaneously differentiate into vascular smooth muscle cells (SMCs) and ECs in 2D culture. Under hypoxic conditions, iVPCs also secreted angiogenic cytokines such as vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) as measured by enzyme-linked immunosorbent assay (ELISA). A longitudinal micro-scaffold made from poly(lactic-co-glycolic acid) was sufficient for the growth and delivery of iVPCs. Co-cultured ECs and SMCs aligned well on the micro-bundle scaffold similarly as in the vessels. 3D cell/polymer micro-bundles formed by iVPCs and micro-scaffolds were transplanted into the ischemic myocardium in a rat model of myocardial infarction (MI) with ligation of the left anterior descending artery. Our in vivo data showed that iVPCs on the micro-bundle scaffold had higher survival, and better retention and engraftment in the myocardium than free iVPCs. iVPCs on the micro-bundles promoted better cardiomyocyte survival than free iVPCs. Moreover, iVPCs and iVPC/polymer micro-bundles treatment improved cardiac function (ejection fraction and fractional shortening, endocardial systolic volume) measured by echocardiography, increased vessel density, and decreased infarction size [endocardial and epicardial infarct (scar) length] better than untreated controls at 8 weeks after MI. We conclude that iVPCs grown on a polymer micro-bundle scaffold are new promising approach for cell-based therapy designed for cardiovascular regeneration in ischemic heart disease.

Description
An account of the resource
Structural characteristics of normally calcifying leg tendons of the domestic turkey Meleagris gallopavo have been observed for the first time by tapping mode atomic force microscopy (TMAFM), and phase as well as corresponding topographic images were acquired to gain insight into the features of mineralizing collagen fibrils and fibers. Analysis of different regions of the tendon has yielded new information concerning the structural interrelationships in vivo between collagen fibrils and fibers and mineral crystals appearing in the form of plates and plate aggregates. TMAFM images show numerous mineralized collagen structures exhibiting characteristic periodicity (54-70 nm), organized with their respective long axes parallel to each other. In some instances, mineral plates (30-40 nm thick) are found interspersed between and in intimate contact with the mineralized collagen. The edges of such plates lie parallel to the neighboring collagen. Many of these plates appear to be aligned to form larger aggregates (475-600 nm long x 75-90 nm thick) that also retain collagen periodicity along their exposed edges. Intrinsic structural properties of the mineralizing avian tendon have not previously been described on the scale reported in this study. These data provide the first visual evidence supporting the concept that larger plates form from parallel association of smaller ones, and the data fill a gap in knowledge between macromolecular- and anatomic-scale studies of the mineralization of avian tendon and connective tissues in general. The observed organization of mineralized collagen, plates, and plate aggregates maintaining a consistently parallel nature demonstrates the means by which increasing structural complexity may be achieved in a calcified tissue over greater levels of hierarchical order.
