The invention relates to the technical filed of tissue engineering and 3D printing, particularly relates to an artificial tissue progenitor and a method for preparing the same. In particular, the invention relates to an artificial tissue progenitor comprising a solid support and a plurality of microcapsules, wherein at least one microcapsule is attached to the solid support, and the microcapsule comprises a cell and a biocompatible material encapsulating the cell, to a method for preparing the artificial tissue progenitor, to a kit and a package useful for preparing the artificial tissue progenitor, to an artificial tissue obtained by culturing the artificial tissue progenitor, such as an artificial lumen, to a lumen implant or a lumen model containing the artificial tissue progenitor or the artificial lumen, to use of the artificial tissue progenitor in the manufacture of an artificial tissue, a lumen implant or a lumen model, and to use of the artificial tissue in the manufacture of a lumen implant or lumen model.

The present disclosure relates to a liver organoid, more specifically, to a liver organoid in which a liver lobule-type structure can be maintained for a long time and a preparation method using the same. The liver organoid of the present disclosure comprises: a tubular outer cavity the inside of which is divided into a plurality of compartments; a cell aggregate loaded into the compartments; and an inner cavity located at the core of the outer cavity.

The disclosure relates to a melt electrowritten soft tissue scaffold and methods of making the same. The scaffold has a body having a first region comprising a first set of fibres and a second set of fibres, the first region being anisotropic. The first set of fibres are arranged approximately parallel relative to one another, each fibre of the first set of fibres has a serpentine arrangement forming peaks and troughs, the first set of fibres has a first Young's modulus. The second set of fibres are arranged approximately parallel relative to one another, the second set of fibres being arranged transversely relative to the first set of fibres, each fibre of the second set of fibres has a serpentine arrangement forming peaks and troughs, the second set of fibres has a second Young's modulus. The first Young's modulus is unequal to the second Young's modulus. In some embodiments the body further comprises a second region extending from the first region. The second region supports the first region.

Provided are compositions and methods of using engineered myogenic cells for delivery of an agent to an individual. Also provided are methods of producing reprogrammed myogenic cells from adult myogenic cells, and use of the reprogrammed myogenic cells for therapy and agent delivery.

The disclosure provides three-dimensional cross-linked scaffolds generated from peripheral blood plasma, and methods for making and using such scaffolds.

The disclosure provides three-dimensional cross-linked scaffolds generated from cord blood plasma, and methods for making and using such scaffolds.

Various embodiments are described herein for creating a 3D human heart model for modelling arrythmias, wherein the method comprises seeding a structure with a mixture of human cardiomyocytes, cardiac fibroblasts and a fibrin mixture to form cardiac tissue; applying a plating media for settlement and compaction of the cardiac tissue; and adding an arrhythmogenic media to the cardiac tissue, where the arrhythmogenic media comprises methyl-beta cyclodextrin for disrupting calcium signaling.

A graft or construct including an isolated cartilage chondrocytes from young donors (<20 years), seeded on a three-dimensional membrane composed of one of the main chondrogenesis-promoting substances (hyaluronic acid), in high densities (1×106) with autologous serum and sealed with a fibrin adhesive for the treatment of a cartilage lesion, with tissue formation that has greater durability, at a lower cost and with fewer risks than the treatments currently available for the management of such lesions. Likewise, a procedure for the treatment of articular cartilage lesions is provided, through the implantation of allogeneic chondrocyte grafts that present the capacity to generate or repair satisfactorily the cartilage of the lesion.

The present invention relates to a chemokine expressing cell. Said cell expresses an exogenous IL-21R binding protein or an exogenous IL-21 and an exogenous chemokine. Further provided is a cell expressing an exogenous receptor, an exogenous IL-21R binding protein or an exogenous IL-21 and an exogenous chemokine. The cell involved is not only effective in solid tumor cells in vitro, but also has an excellent killing effect on solid tumor cells in vivo.

The present invention relates to a protein-based three-dimensional tissue scaffold and the method of the manufacture thereof. Instant scaffolds are particularly useful in tissue reconstruction, in particular in wound treatment and as dermal replacement scaffolds.
