143 results about "Angiogenesis Factor" patented technology

Angiogenic factor. Any of a group of substances present in the circulation (most of which are polypeptides—e.g., angiogenin, fibroblast growth factor, transforming growth factors and some lipids) which play a role in blood vessel formation. Angiogenic factors are increased after myocardial ischaemia.

Treatment for heart disease

InactiveUS20070059288A1Poor cell survival and engraftmentImprove heart functionBiocideVirusesDiseaseCORONARY ARTERY DISEASE/MYOCARDIAL INFARCTION
The present invention provides a system for treating heart disease using a combination of pro-angiogenesis therapy and cellular cardiomyoplasty. The system is particularly useful in treating patients with damaged myocardium due coronary artery disease, myocardial infarction, congestive heart failure, and ischemia. A pro-angiogenic factor (e.g., VEGF) or a means of delivering a pro-angiogenic factor (e.g., a genetically engineered adenovirus, adeno-asssociated virus, or cells) is administered to the heart in order to promote new blood vessel growth in an ischemic or damaged area of the patient's heart. Cells such as skeletal myoblasts or stem cells (e.g., mesenchymal stem cells) with the potential to divide, differentiate, and integrate themselves into the injured myocardium are then administered into the affected area of the heart. By inducing new blood vessels growth in the injured myocardium, the cells are better able to grow and become an integral part of the heart. The invention also provides kits for use in treating a patient using the inventive method. Such kits may contain cells, catheters, syringes, needles, cell culture materials, polynucleotides, media, buffers, etc.

Provided are methods and compositions for the photodynamic therapy (PDT) of ocular conditions characterized by the presence of unwanted choroidal neovasculature, for example, neovascular age-related macular degeneration. The selectivity and sensitivity of the PDT method can be enhanced by combining the PDT with an anti-angiogenesis factor, for example, angiostatin or endostatin, or with an apoptosis-modulating factor. Furthermore, the selectivity and sensitivity of the PDT may be further enhanced by coupling a targeting moiety to the photosensitizer so as to target the photosensitizer to choroidal neovasculature.

Methods for improving cell therapy and tissue regeneration in patients with cardiovascular and neurological diseases by means of shockwaves

InactiveUS20060246044A1Improving targeted recruitmentReduced ability to homeBiocideNervous disorderShock waveEtiology
Improving cell therapy and tissue regeneration in a patient suffering from a cardiovascular or a neurological disease by treating a tissue of the patient with shock waves and / or applying to the patient a therapeutically effective amount of stem cells and / or progenitor cells. Such treatment increases expression of chemoattractants, pro-angiogenic factors, and pro-survival factors. The chemoattractants can be, for example, vascular endothelial growth factor (VEGF) or stromal cell derived factor 1 (SDF-1). For example, the treated tissue can be located in the patient's heart or in a skeletal muscle of the patient, and the shock waves can be extracorporeal shock waves (ESW) or intracorporeal shock waves. The cardiovascular disease can have an ischemic or non-ischemic etiology. For example, the cardiovascular disease can be a myocardial infarction, ischemic cardiomyopathy, or a dilatative cardiomyopathy. For example, the neurological disease can be a peripheral neuropathy or neuropathic pain.

Myoblast cells obtained by culturing, particularly from satellite cells or other progenitor cells, are transplanted into tissue such as diseased heart tissue to form healthy repair tissue and reverse disease. This technique can be carried out in various ways and preferably includes a cellular integration factor to assist cellular survival, integration and longevity into the treated organ. Angiogenesis factors such as vascular endothelial growth factor are particularly preferred and may be transgenically expressed by the transplanted cell. Other factors that may be used to augment the procedure include migratory and scaffolding molecules. The methods and materials are particularly useful in combination with an automated cell processor and an automated catheter delivery system.

Injectable modified hyaluronic acid, preparation method for same and composition

The invention discloses injectable modified HA (hyaluronic acid), a preparation method for the same and a composition. -OH in -COOH in an HA structural unit is partially substituted by a group shown in the original document, and the substitution rate is not lower than 40 percent. The modified HA can be directly reacted with chitosan to form hydrogel without chemical cross-linking reaction and damage to the structure of the HA. Rheodynamic experiments show that AHA-CS can be prepared into injection, and the formed hydrogel is stable in structure. Animal experiments show that the AHA-CS hydrogel has the effects of accelerating the healing of wounds and promoting cell proliferation and keratinocyte migration. Histological detection for the wounds treated by the hydrogel also proves that the hydrogel has the effect of promoting the formation of granulation tissues and capillaries. The expression of MRNA (messenger ribose nucleic acid) such as a VEGF-A (vascular endothelial growth factor), an SDF-1 (stromal-derived factor-1) and MMPs (matrix metalloproteinases) at the wounds treated by the hydrogel is increased or upregulated. Significantly, new hair follicles are found on the wounds treated by the hydrogel.
