Embodiments described herein relate generally to a three-dimensional ex vivo skeletal muscle tissue comprising a hydrogel and a plurality of cells that includes skeletal muscle cells, at least a portion of the cells being encapsulated inside the hydrogel. In some embodiments, the skeletal muscle tissue is characterized by one or more contractions in response to an electrical and/or chemical stimulation.

A cellular microcompartment comprising: at least one layer of cells, an outer layer of hydrogel, and a fibrin mesh arranged between the outer layer of hydrogel and said layer of cells, the cellular microcompartment being compliant with regulations for Good Manufacturing Practices (GMP) and suitable for clinical applications, as well as methods for preparing the cellular microcompartment, and methods in which the cellular microcompartment is used for production of cells and/or tissues, including a large-scale production.

A three dimensional (3D) model of a tumor made of a synthetic material and a plurality of cell types, including malignant cells and non-malignant cells of the tumor, having a full HLA match, such that the synthetic material and the plurality of cell types are arranged in high matchability to a 3D image of the tumor, is provided. Methods of forming the 3D tumor model by bioprinting are also provided, as well as systems in which the 3D tumor model can be perfused and fluidly connected to a medium containing immune cells and/or other cells and factors present in the tumor's microenvironment. Methods utilizing the 3D tumor model or the system in, for example, personalized therapy, are also provided.

Implantable scaffolds that treat solid tumors and escape variants and that provide effective vaccinations against cancer recurrence are described. The scaffolds include genetically-reprogrammed lymphocytes and a lymphocyte activating moiety.

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.

Described herein are a system, device, methods and compositions related to generating 3-dimensional cardiac tissues. Also described herein are a system, device, and methods of maturing 3-dimensional cardiac tissues and maintaining their viability in culture.

Methods of tissue grafting, and more particularly methods for enhancing tissue graft revascularization, e.g., host engagement of pre-existing graft blood vessels.

Provided herein are novel methods and composition utilizing adipose tissue-derived stromal stem cells for treating fistulae.

There is provided a tissue scaffold and a method for making a tissue scaffold. The tissue scaffold comprises elastin and optionally fibrin and/or collagen. The elastin in the scaffold may be cross-linked. The elastin that is cross-linked preferably comprises solubilised elastin and is unfractionated.
