摘要:
An immunotherapy delivery device is provided including a catheter and a pressure modulating device fixed adjacent the distal end of the catheter. In accord with aspects of the device, the lumen of the catheter is coated to facilitate delivery of a healthy immunotherapy agent. A method for delivering an immunotherapy agent to a tumor includes advancing the delivery device into a vessel of a patient, and infusing the agent under pressure into the vessel to penetrate the tumor. The delivery device prevents reflux of the agent toward non-treatment sites.
摘要:
A method to provide an inflated decellularized extracellular matrix of a mammalian organ or a vascularized portion thereof, or a mammalian vascularized tissue or a vascularized portion thereof, an inflated decellularized extracellular matrix of a mammalian organ or a vascularized portion thereof, or a mammalian vascularized tissue or a vascularized portion thereof, and uses thereof, are provided.
摘要:
Methods and devices for tissue remodeling and repair of collagenous tissues, including tendons, ligaments, and bone, as well as scalable connective tissue manufacturing, are provided. Collagen fibers are assembled by extensional strain-induced flow crystallization of collagen monomers. Extensional strain also drives the fusion of already formed short collagen fibrils to produce long-range, continuous fibers. Wearable devices for controlled tissue remodeling and wound healing deliver a tissue remodeling solution to a tissue repair site. The remodeling solution, together with appropriate application of strain to the tissue remodeling site, accelerate healing, prevent injury, and reduce scar formation.
摘要:
The present invention relates to compositions and methods utilizing hair follicle derived Non-Bulbar Dermal Sheath cells for use in the treatment of dental-related conditions, including the treatment of gingivitis. Briefly stated, the present invention provides compositions and methods for treating or preventing a wide variety of conditions associated with the oral cavity, including for example, periodontal disease and a variety of diseases or injuries associated with the gingiva utilizing hair follicle derived Non-Bulbar Dermal Sheath ("NDBS") cells. Within one aspect of the invention methods are provided for isolating NBDS cells, comprising the steps of: preparing vital hair and cleaving the hair.
摘要:
The present invention describes methods and compositions of hydrogel microspheres for inducing macrophage conversion by sequentially converting a first population of wound macrophages in a wound to M2A macrophages by exposing the first population of wound macrophages to IL-4 and converting a second population of wound macrophages to M2C macrophages by exposing the second population of wound macrophages to IL-10. One aspect describes a method of inducing macrophage conversion in a wound. Another aspect describes compositions and methods of preparing a hydrogel microsphere for wound healing. Yet another aspect describes methods for treating a chronic wound with hydrogel microspheres.
摘要:
A composition for loading into a structural element of a stent, where the structural element is defined by a lumen and at least one opening to access the lumen. The composition may comprise a therapeutic agent, and a chelator, a precipitation agent, or a combination thereof. Medical devices, such as stents, with a structural element defined by a lumen and at least one opening to access the lumen, filled with the compositions are also described.
摘要:
The present disclosure provides methods and compositions, including a placental extract, for inducing and/or modulating angiogenesis; methods of identifying modulators of angiogenesis, and assays for identifying modulators of angiogenesis. The present disclosure also provides methods of making a composition, including a placental extract that can induce and/or modulate angiogenesis.
摘要:
The methods and compositions disclosed herein are effective in the promoting the reattachment of delaminated cartilage to bone. The methods (and related compositions) comprise the removal of the acellular layer of the delaminated cartilage thereby exposing the underlying chondrocyte cells thereby allowing the promotion of the reattachment of the delaminated cartilage.
摘要:
The present invention provides compositions for treating soft tissue injuries comprising a collagen matrix and mesenchymal stem cells adhered to the collagen matrix. Methods of making and using compositions comprising a collagen matrix and mesenchymal stem cells adhered to the collagen matrix are also provided.
