A polymeric medical device/implant coating is disclosed for the delivery of drugs or therapeutic compounds such as antibiotics over an extended period of time and at levels or concentrations that exceed the MIC. In one embodiment, an antibiotic such as vancomycin is encapsulated in a photo-crosslinked poly(lactide-co-glycolide) (PLGA)-dimethacrylate coating. The drug release profile of this coating was studied and the initial burst was reduced by photo-crosslinking. Due to photo-crosslinking, an additional diffusional resistance was created, which prevented easy diffusion of the drug into the release medium. Moreover, the time required for this coating process is very quick (e.g., around 5 minutes) and makes it compatible for this coating to be applied in the operating room.

The present invention concerns a polyelectrolyte coating comprising at least one polycationic layer consisting of at least one polycation consisting of n repetitive units having the formula (1) and at least one polyanionic layer consisting of hyaluronic acid. The polyelectrolyte coating has a biocidal activity and the invention thus further refers to the use of said polyelectrolyte coating for producing a device, in particular a bacteriostatic medical device, more particularly an implantable device, comprising said polyelectrolyte coating, and a method for preparing said device and a kit.

The invention relates to plasmids capable of expressing a protein targeting immune cells when transformed into a lactic acid bacterial cell, wherein the protein is chosen from the group consisting of murine and human CXCL12 1α; CXCL17 and Ym1. The invention further relates to lactic acid bacteria transformed with a said plasmid, as well as the use of said lactic acid bacteria for wound healing in humans and animals.

The present disclosure provides engineered tissue constructs having a population of cells, such as hepatocytes and stromal cells, and methods of making and using the same (e.g., for treating a disease or disorder, such as acute liver failure, a urea cycle disorder, or hyperbilirubinemia (e.g., in a subject having Crigler-Najjar syndrome) in a human subject in need thereof).

The present invention provides devices and methods for delivering a population of cells or a therapeutic agent to a subject in need thereof.

The present disclosure provides synthetic collagen and methods of making and using synthetic collagen that include a synthetic collagen that facilitates wound closure comprising an isolated and purified triple helical backbone protein that facilitates wound closure comprising one or more alteration in a triple helical backbone protein sequence, that stabilize the isolated and purified triple helical backbone protein and does not disrupt an additional collagen ligand interaction; and one or more integrin binding motifs, wherein the isolated and purified triple helical backbone protein facilitates wound closure.

An autologous bone graft substitute composition for inducing new bone formation, promoting bone growth and treating bone defects, a method of preparation thereof, and a method of inducing or promoting bone growth by treatment of a bone with an autologous bone graft substitute composition. The composition includes autologous blood; one or more analogs of an osteogenic bone morphogenetic protein selected from BMP-6, BMP-2, BMP-7, BMP-4, BMP-5, BMP-8, BMP-9, BMP-12, and BMP-13, and combinations thereof; and a compression resistant matrix selected from the group consisting of a bone autograft, bone allograft, hydroxyapatite, tri-calcium phosphate, and combinations thereof. The autologous blood forms a coagulum gel comprising a fibrin-meshwork reinforced with the compression resistant matrix and containing the osteogenic bone morphogenetic protein which is released over a sustained period.

Disclosed is a patch or bandage for tissue regeneration and/or repair. The bandage comprises i) one or more proteins from the Wnt family, or an agonist of the Wnt signalling pathway; and ii) a scaffold, wherein the one or more Wnt proteins or Wnt agonist is immobilised on the scaffold, and wherein the scaffold is formed from a functionalised biocompatible polymer.

Described herein is a bifunctional peptide, compositions comprising the same, and methods useful for treatment of peri-implant disease.
