The present invention relates to a three-dimensional multiphasic synthetic tissue scaffold comprising first, second and third compartments, wherein: each said compartment comprises distinct microstructural, and/or chemical, and/or mechanical properties, and is connected with at least one other compartment of the scaffold via a continuous interface; the tissue scaffold is porous; and the external morphology of the tissue scaffold mimics that of a mammalian joint or a component thereof. The invention further relates to a method for producing the three dimensional multiphasic synthetic tissue scaffold using a polymeric material, the method comprising using a three-dimensional (3D) bioprinter to print the tissue scaffold by continuously deposit the polymeric material onto a platform until the tissue scaffold is produced in its entirety.

The present invention relates to artificial skin having structure and properties by age, and more specifically to artificial skin having structure and properties, for which effective analysis and application are possible on the basis of age of the skin, as the human skin can be replicated according to age by simple control in the internal structure of properties such as height and width, and a method for manufacturing the same.

The present invention is directed to wound healing scaffolds cografted with a population of stem cells, wherein the population of stem cells are ABCB5+ stem cells. The scaffolds are, for instance, collagen glycosaminoglycan scaffolds.

A filter assembly for a surgical suction system. The filter assembly has a containment defining a filter chamber an intake fitting on an upstream end of the chamber, an output fitting on an opposite downstream end of the chamber, and a filter element in the filter chamber and made at least partially of a bioresorbable bone substitute so that autologous tissue components carried in a fluid flowing from the fitting through the filter element in the filter chamber are trapped by the filter element.

Devices and methods for transplanting cells in a host body are described. The cell comprises a porous scaffold that allows the ingrowth of vascular and connective tissues, a plug or plug system configured for placement within the porous scaffold, and a seal configured to enclose a proximal opening in the porous scaffold. The device may further comprise a cell delivery device for delivering cells into the porous scaffold. The method of cell transplantation comprises a two step process. The device is incubated in the host body to form a vascularized collagen matrix around a plug positioned within the porous scaffold. The plug is then retracted from the porous scaffold, and cells are delivered into the vascularized space created within the porous scaffold.

The invention relates to a liver microtissue, preferably, the liver microtissue having the largest dimension between 500 and 700 μm, and the liver microtissue expressing CYP3A4 monooxygenase with an activity of at least 75,000 RLU per million cells and producing at least 18 ag of urea per million cells per 24 hours. The invention also relates to a method for producing the liver microtissue from pluripotent stem cells, and uses of the liver microtissue in treatment and/or prevention of liver failure.

The present invention provides compositions and methods for improving cardiac function. Specifically, the present invention provides compositions and methods for treating a subject having a disorder or condition associated with aberrant cardiac tissue function, comprising contacting a patient having a disorder or condition associated with aberrant cardiac tissue function with a construct, or a construct associated with therapeutic cells, or a construct associated with fibroblast cells and therapeutic cells.

The present invention relates to new plasma or new platelet-rich plasma preparations, new cell dissociation methods, new cell associations or compositions, a method of preparation thereof, a use thereof, devices for the preparation thereof and preparations containing such a platelet-rich plasma preparation and cell associations or compositions. Specifically, the invention provides plasma or platelet-rich plasma alone or in cell composition preparations for use in tissue regeneration and bone regeneration and pain reduction.

The present invention is directed to wound healing scaffolds cografted with a population of stem cells, wherein the population of stem cells are ABCB5+ stem cells. The scaffolds are, for instance, collagen glycosaminoglycan scaffolds.

A method for regeneration or repair of an infarcted myocardium including an infarcted region in an animal comprising injecting into the animal a composition including one or more gold nanostructures is disclosed.
