The cell encapsulation system (CES) device is a device used for dermal, subdermal, muscle, tissue, or organ implantation into an individual (host) that is capable of being loaded with and carrying and containing exogenously introduced cells (encapsulated cells) that can produce relevant biochemicals (factors) and/or therapeutic molecules that can be transported to the host tissue while simultaneously not eliciting a significant host immune response (to the implanted device or to the encapsulated cells). The CES device provides a means of local and/or systemic, prolonged delivery of single or multiple factors and/or therapeutic molecules to alleviate, treat, or cure a variety of acute and chronic pathologies and ailments.

Biointegrative implantable cell encapsulation device and system

Disclosed are Self-Gelling materials and structures or materials or structures having one or more self-gelling components that overcome existing gel limitations due to hydrogel localization for medical applications by providing, for example, 1) microstructurally, or physically, anchored characteristics to help localize the gel, and the overall printed, or otherwise formed structure, giving structural form to the gel that allows the gel to be localized within the body, and even sutured in place, and mitigates gel migration and extends its residence time; 2) to provide an underlying 3D printed structure to help contain and support the gel after implantation; and more. Self-Gelling 3D printed structures may be further processed via milling to yield deconstructed scaffold micro-granules, with the composition and nano-/micro-structure of the original larger structure. Deconstructed scaffold micro-granules may be hydrated to form a micro-granule embedded gel network that can be injected, giving form to injectable gels.

Method for fabrication of additively manufactured, self-gelling structures and their use

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 μm 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.

Surgically-friendly tissue papers from organ-specific decellularized extracellular matrices

Compositions for forming porous materials and three-dimensional objects, including fibers, films and coatings made from the materials are provided. Also provided are methods for forming the porous objects from the compositions. The compositions include a solvent, a polymer binder that is soluble in the solvent, and solid particles that are insoluble in the solvent. The solid particles include water-soluble salt particles that can be selectively dissolved from objects made from the compositions to render the resulting structures porous.

The three-dimensional metal oxide object is exposed to a reducing gas at a temperature and for a period of time sufficient to reduce and to sinter the metal oxide particles to form a three-dimensional metallic object. Depending upon the composition of the metal oxide paste, the three-dimensional metallic object may be composed of a single metal, a simple or complex metal-metal alloy, or a metal-ceramic composite.
