Provided herein are inks including decellularized extracellular matrix (dECM) particles and scaffolds made from the inks. Also provided are methods of making the scaffolds and applications for the scaffolds. In an embodiment, a porous scaffold comprises dECM particles and an elastomer, wherein the scaffold is planar having a thickness of about 100 m or greater, the scaffold comprises irregularly shaped pores having a random orientation and distribution throughout the scaffold, and the scaffold is free of crosslinking between the molecular components of the scaffold.

Provided are methods for the treatment and prevention of fibrosis at a medical implant site in a subject, by administering a microporous gel to the medical implant site. Also provided are methods of preventing or treating an infection at the medical implant site in a subject. Also disclosed herein are methods for promoting healing of a wound or surgical incision at a medical implant site in a subject, by administering a microporous gel to the medical implant site. The microporous gel may be fluidic during application and annealed or crosslinked after application. The microporous gels may contain various therapeutic agents, including antibiotics and analgesics, throughout the gel.

Disclosed herein are systems for promoting healing of a wound or surgical incision at a medical device site (e.g., implanted medical device) in a subject, by administering a microporous gel to the medical implant site. Also disclosed are systems for the treatment and prevention of infection at a medical implant site in a subject, by administering a microporous gel to the medical implant site. The microporous gel may be fluidic during application and annealed or crosslinked after application. The microporous gels may contain various therapeutic agents, including antibiotics and analgesics, throughout the gel.

Disclosed herein are methods of manufacturing injectable microgel scaffolds, including methods of producing, purifying and concentrating microgel particles therein. The microgel scaffolds of the present disclosure are useful for a wide range of applications, such as stabilizing an implanted medical device in an implant site in a subject.

The microgel scaffolds may contain various therapeutic agents, including antibiotics and analgesics, throughout the gel.

The invention features compositions and methods for repairing musculoskeletal defects or injuries using a bioactive scaffold comprising fibrinogen, thrombin, SDF-1 and/or KGN as well as methods of making the scaffold.

Disclosed are a bifunctional peptide having the capability to permeate cells and the capability to regenerate muscles and the use thereof. Advantageously, the bifunctional peptide has a function of regenerating muscle cells and thus is useful for the prevention or treatment of diseases affecting muscle regeneration, and additionally has the capability to permeate cells and thus eliminates the necessity to adhere an additional peptide or add other agent or drug for cell permeation of the peptide, thereby finally exerting an efficient muscle generation effect. Thus, the bifunctional peptide can be easily applied to various surgical regenerative treatments and can shorten the treatment period.

A high molecular weight polyethylene polymer is formulated so that the polymer is capable of being injection molded. The polyethylene polymer has a Viscosity Number of greater than about 400 ml/g and has a melt flow rate of greater than about 0.9 g/10 min. The polyethylene polymer is of high purity and is particularly well suited for producing medical products.
