The present invention generally relates to uses of glial cell line-derived growth factor (GDNF) in cutaneous wound healing and hair growth. Methods of effecting hair growth and / or wound healing which feature administration of GDNF, or a biologically active fragment thereof, to subjects, e.g., human subject, are disclosed herein. The invention relates also to formulations and kits for achieving the indicated pharmaceutical advantages.

Concentrating devices, systems, and methods include those for separating fluids to be sensed (e.g., analytes, such as volatile organic compounds (VOCs) and / or other chemical substances) from other fluid (e.g., a carrier gas, air, etc.) of a fluid mixture received from a target area of a subject's anatomy (e.g., a subject's skin, a wound on a subject, etc.). In some cases, the concentration system may include a housing and a rotor positioned in a compartment of the housing. The housing may receive a fluid mixture in the compartment and rotation of the rotor relative to the housing may separate fluid to be sensed in the fluid mixture from other fluid of the fluid mixture.

Methods and compositions for treating a cutaneous wound to treat or limit development of a pathogenic bacterial infection are provided, involving administering to a subject having a cutaneous wound an amount effective of Corynebacteria spp., or a disclosed, composition, to treat or limit development of pathogenic bacterial infection of the wound.

The present disclosure provides compositions and methods for enhanced healing of wounds, e.g. cutaneous wounds, by application of a scaffold or matrix, e.g. a hydrogel, comprising an effective dose of edited dendritic cells (DCs). As used herein, edited dendritic cells refers to mammalian, usually human, dendritic cells that have been genetically modified to alter expression of one or more genes involved in wound healing. In some embodiments edited DC are modified to downregulate or substantially eliminate expression of N-myc downregulated gene 2 (Ndrg2) expression, which cells may be referred to as Ndrg2 KO DCs.

Provided is a recombinant fibronectin fusion protein comprising a recombinant fibronectin mutant and platelet factor 4, wherein the recombinant fibronectin fusion protein has an amino acid sequence as set forth in SEQ ID NO: 3 or SEQ ID NO: 4, and a molecular weight of not more than 90 kDa. The recombinant fibronectin fusion protein exhibits good solubility, has a simple preparation process, and is conveniently purified. The recombinant fibronectin fusion protein comprises a new recombinant fibronectin, and can inhibit inflammation during wound healing, and promote cutaneous wound healing in mice. When platelet factor 4 is fused to the N-terminus of the recombinant fibronectin mutant, cell proliferation activity can be significantly and effectively enhanced.

Mammals typically heal with fibrotic scars. Treatments to regenerate human skin and hair without a scar remain elusive. Mice lacking C-X-C motif chemokine receptor 2 (CXCR2-KO) displayed robust and complete tissue regeneration across three different injury models, including skin, hair follicle, and cartilage. Remarkably, wild type mice receiving plasma from CXCR2-KO mice through parabiosis or injections healed wounds scarlessly. A comparison of circulating proteins using multiplex ELISA revealed a 24-fold higher plasma level of granulocyte-colony stimulation factor (G-CSF) in CXCR2-KO blood. Local injections of G-CSF into WT mouse wound beds reduced scar formation and increased hair follicle regeneration by 6-fold. G-CSF directly polarized macrophages into an anti-inflammatory phenotype, and both CXCR2-KO and G-CSF-treated mice recruited more anti-inflammatory macrophages into injured areas. These results improve our molecular understanding of scarless tissue regeneration and introduce a new therapeutic approach for cutaneous wounds and hair regeneration. Provided are compositions and methods relating to treating wound healing pathologies.

The present invention relates to the therapeutic use of a composition for the treatment of cutaneous wounds such as acute wounds, chronic wounds or epidermolysis bullosa wounds. The composition according to the invention is based on ABA-type triblock copolymers, comprising two thermoplastic styrene end blocks A and an elastomeric central block B which is a saturated olefin, comprising at least one resin selected from aromatic resins usable in particular for producing an interface dressing with a framework or support or self-supporting.

The invention provides a hemodialysis pipeline fixing dressing plaster, and belongs to the technical field of medical supplies, the hemodialysis pipeline fixing dressing plaster comprises a wound, the top of the wound is provided with skin, the top of the wound is movably connected with a first dialysis tube, one end of the first dialysis tube is fixedly provided with a transfer interface, and one side of the transfer interface is fixedly provided with a second dialysis tube; a main fixing mechanism is arranged at the bottom of the second dialysis tube, a secondary fixing mechanism is arranged at the top of the main fixing mechanism, and the main fixing mechanism comprises a base material layer, a longitudinal rod, a transverse rod, an air hole, a buffer pad, a water absorption pad, a clamping plate and a clamping groove; by arranging the clamping plate, the clamping groove formed in the clamping plate is coated with mucilage glue, when the clamping plate is used in cooperation with the fourth bandage and the third bandage, the hemodialysis tube can be well fixed to the top of the clamping plate, and the situation that the hemodialysis tube and the transfer connector loosen and fall off due to shaking of the hemodialysis tube is prevented.
