TUBULAR TISSUE CONSTRUCT AND A METHOD OF PRINTING

A 3D printed tubular construct, such as a nephron, with or without embedded vasculature as well as methods of printing tubular tissue constructs are described.

Shape memory polymer scaffolds for tissue defects

A method of making a shape memory polymer (SMP) tissue scaffold includes forming a salt template and adding a macromer solution to the salt template. The macromer solution may include a photoinitiator solution. The method includes drying the SMP scaffold and leaching salt from the SMP scaffold. A coating is then applied to the SMP scaffold. The coating may be applied either before or after heating the SMP scaffold.

Porous Polysaccharide Scaffold Comprising Nano-Hydroxyapatite and Use for Bone Formation

The present invention relate to three dimensional porous polysaccharide matrices able to induce mineralisation of a tissue in osseous site, as well as in non-osseous site, in the absence of stem cells or growth factors.

Methods and systems for scaffolds comprising nanoelectronic components

The present invention generally relates to nanoscale wires and tissue engineering. Systems and methods are provided in various embodiments for preparing cell scaffolds that can be used for growing cells or tissues, where the cell scaffolds comprise nanoscale wires. In some cases, the nanoscale wires can be connected to electronic circuits extending externally of the cell scaffold. Such cell scaffolds can be used to grow cells or tissues which can be determined and/or controlled at very high resolutions, due to the presence of the nanoscale wires, and such cell scaffolds will find use in a wide variety of novel applications, including applications in tissue engineering, prosthetics, pacemakers, implants, or the like. This approach thus allows for the creation of fundamentally new types of functionalized cells and tissues, due to the high degree of electronic control offered by the nanoscale wires and electronic circuits.

The biocompatible and biodegradable elastomer of present invention can be used to produce vascular graft, cell carrier, drug carrier or gene carrier.

POROGEN COMPOSITIONS, METHODS OF MAKING AND USES

Provided are porogen compositions and methods of using such porogen compositions in the manufacture of porous materials, for example, porous silicone elastomers. The porogens generally include comprising a core material and shell material different from the core material. The porogens can be used to form a scaffold for making a resulting porous elastomer when the scaffold is removed.

Process for producing polymer foams

Process for the production of a polymer foam with use of hydrogel pearls as porosity generating template, comprising the steps of:providing a matrix of polymer or prepolymer in viscous state including, as a dispersed phase, hydrogel pearls, where said pearls are dispersed in said matrix so as to generate intercommunicating cells,causing the solidification of the matrix of polymer or prepolymer to obtain said polymer foam including said hydrogel pearls, characterised in that it comprises the operation of subjecting the thus obtained foam to conditions which cause the dehydration of said hydrogel pearls so as to obtain a reduction of volume of said pearls andremoving the dehydrated pearls by immersion in water of the polymer foam or by exposure of the foam to a flow of pressurized gas or water.
