Abstract of Disclosure The present invention provides methods and compositions for attenuating expression of a target gene in vivo. In general, the method includes administering RNAi constructs (such as small-interfering RNAs (i.e., siRNAs) that are targeted to particular mRNA sequences, or nucleic acid material that can produce siRNAs in a cell), in an amount sufficient to attenuate expression of a target gene by an RNA interference mechanism, e.g., in a sequence-dependent, PKR-independent manner. In particular, the subject method can be used to alter the growth, survival or differentiation of cells for therapeutic and cosmetic purposes.

A surgical stent made of biocompatible material for implantation in human tissue to enable blood and nutrients to flow from an area of vascular tissue to an area of tissue with little or no vasculature.

Methods and compositions are provided for circularizing target sequences in a sample. In particular, ligation oligonucleotides are employed to selectively hybridize with the target such that the target can be ligated into a closed circular target. Rolling circle amplification can then be performed directly on the target sequence for subsequent detection and analysis.

Methods and compositions for treating or ameliorating lower back pain by administering an effective amount of one or more cell types, alone, and/or in combination with a matrix, and/or in combination with growth factors, in order to stimulate lumbar angiogenesis, decrease inflammation, and stimulating regeneration.

The present invention relates to methods and apparatuses for use in revascularization of damaged areas of myocardium through application of one or more radiation type treatment modalities.

Methods and devices for increasing revascularization in an ischemic heart and for reducing muscle mass or volume in congestive heart failure patients are described. The method includes using laser energy to create microchannels in the target tissue. The microchannels are separated from each other to maintain tissue that is untreated or undamaged by laser energy. Such undamaged tissue augments angiogenesis. The method also includes delivery of bioactive agents that are angiogenic. The apparatus simultaneously creates a plurality of microchannels that are separated from each other and thereby promote angiogenesis, revascularization and/or muscle reduction.

An improved prosthetic graft for the bypass, replacement or repair of vessels and organs that are in contact with blood flow is disclosed. The prosthetic graft includes a porous prosthetic implant and adherent cells adhered to the outer surface of the implant. The adherent cells are transfected with at least one recombinant nucleic acid molecule encoding at least one protein that enhances patency of the graft. The prosthetic graft has a long-term patency and success rate that is superior to other previously described prosthetic grafts designed for such use. Also disclosed are methods of making and using such a graft.

A method is provided for use with extracted blood, including (a) applying blood to a first gradient suitable for selecting first-pass cells having a density less than 1.077 g/ml; (b) applying the first-pass cells to a second gradient suitable for selecting second-pass cells having a density between 1.055 and 1.074 g/ml; (c) increasing the number of cells having a density between 1.055 and 1.074 g/ml, by culturing the second-pass cells for a period lasting between 3 and 30 days; and (d) identifying endothelial progenitor cells in the cultured cells. Other embodiments are also described.

The invention provides a scaffold of extracellular matrix polymers with recombinant chimeric peptides tethered thereto. The invention also provides recombinant chimeric peptides of antimicrobial peptides and extracellular matrix binding domains. The invention also provides methods for treating chronic wounds using the scaffold and/or recombinant chimeric peptides.

Methods and compositions for rejuvenating neural stem cells and/or progenitor cells, increasing neurogenesis, increasing angiogenesis, and treating or preventing neurodegenerative and neurovascular disorders are disclosed.

CRF peptide analogs that bind to CRFR2 with an affinity far greater than they bind to CRFR1. These analogs exhibit CRF antagonist activity, and they can be based upon the native structures of sauvagine, CRF, and urocortin.

The present invention relates to a therapeutic preventive agent that includes an angiogenic factor gene (such as hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), and hypoxia inducible factor (HIF)) as its active ingredient, and the administration of such an agent into the targeted skin diseases-affected area.

As described below, the present invention features compositions and methods related to the isolation, culture and therapeutic use of CD31-expressing cells.

A microfluidic device for more accurately modeling the in vitro environment in which cancer occurs is disclosed. The microfluidic device includes a surface defining one or more microfluidic channels, a first three dimensional scaffold comprising one or more cancer cells that is spatially separated from the one or more microfluidic channels, a second three dimensional scaffold, at least a portion of which is contacting and in fluid communication with the first three dimensional scaffold, and that is spatially separated from the one or more microfluidic channels, and a third three dimensional scaffold, at least a portion of which is contacting and in fluid communication with the one or more microfluidic channels and the second three dimensional scaffold. The device can be used to assay anti-cancer agents, or as a system for modeling the growth, behavior, or metastasis and tumor formation of cancer cells.

The present invention provides compositions and methods for increasing proliferation, increasing cell cycle activity, and/or proliferation of postmitotic mammalian differentiated cardiomyocytes. The invention can be used to slow, reduce, or prevent the onset of cardiac damage caused by, for example, myocardial ischemia, hypoxia, stroke, or myocardial infarction in vivo. In addition, the methods and compositions of the invention can be used to enhance proliferation of differentiated cardiomyocytes in vitro and/or ex vivo, which can then be used in tissue grafting.

Disclosed are methods of polarizing macrophages to exhibit M2 phenotype, including introducing an effective amount of gingiva-derived mesenchymal stem cells to an environment comprising a population of macrophages such that the macrophages are in fluid communication with the gingiva-derived mesenchymal stem cells. Also disclosed are methods of promoting cutaneous wound healing including administering to a patient an effective amount of human gingiva-derived mesenchymal stem cells, thereby resulting in at least one of accelerated wound closure, rapid re-epithelialization, improved angiogenesis and improved tissue remodeling relative to untreated controls. Also disclosed are methods for attenuating contact hypersensitivity in a patient, the methods including administering to a patient an effective amount of human gingiva-derived mesenchymal stem cells at a time at least timeframe selected from the group consisting of before sensitization, after sensitization and before challenge and after challenge, thereby attenuating contact hypersensitity.

Presented herein are novel protein biomarkers related to cancers with stromal components. These newly identified biomarkers create the basis for multiple (single) assays using traditional bioassay technologies and when used in combination yield exceptional clinical sensitivity and specificity in the determination of diagnosis and/or prognosis of cancer. A new genetic model able to identify potential genetic suppressors and/or potential therapeutic agents for treating stromal cancers is also described. Means and methods for evaluating data generated using multiple biomarkers in order to validate findings and further the use of the biomarkers and the genetic model system in clinical, diagnostic and therapeutic uses is also included.
