This invention discloses a method for the induction of arterial-type of hemogenic endothelium and method of differentiating T cells from hemogenic endothelial cells.

Bioprinting is the layer-by-layer construction of synthetic tissues or scaffolds. Described herein is a motorized extruder which can precisely extrude and retract extrudate such as bioinks in a compact and rapidly-loadable form-factor. This includes a compact bioprinter using a stepper motor coupled with a threaded shaft to directly move the plunger of an extruder. This pneumatic-mechanical system obviates the needs for pneumatic tubing, rods, or other complex elements of existing designs. The direct drive design further allows for a lighter, smaller gantry that is capable of more precise fabrication of bioprinted constructions. This includes delicate vasculature systems that are beyond limits of existing bioprinting technologies.

The present invention refers to a model for in-vitro simulation of the behaviour of dysfunctional human vessels, such as for example vessels affected by aneurysm, stenosis or sclerosis plaques, as an instrument for testing medical devices and drugs with the aim of verifying effectiveness and safety thereof prior to use thereof on humans. Specifically, the present invention refers to an in vitro model of a substantially tubular-shaped vascular structure having dysfunctional anatomical and physiological characteristics simulating the same vascular structure of a healthy subject whose vascular structure has been damaged or deformed or deteriorated due to a damage selected from among the group comprising or, alternatively, consisting of aneurysm, stenosis, sclerosis plaques, forms of tumours or cardiomyopathies having the characteristics as claimed in the attached claims. Furthermore, the present invention also refers to a reliable and reproducible industrialisation process for eliminating air bubbles for producing an engineered vascular tissue for the in vitro test of medicinal products for human use and veterinarian products for animal use.

Provided herein are methods and systems for forming a three-dimensional object corresponding to an organ or organoid. A method for forming a three-dimensional object corresponding to an organ or organoid may comprise generating a plurality of discrete focal points patterned as a 3D projection corresponding to the organ or organoid in a medium comprising one or more precursors of a polymer, to form at least a portion of the 3D object corresponding to the organ or organoid.

The present invention relates to microfluidic fluidic devices, methods and systems as microfluidic kidney on-chips, e.g. human Proximal Tubule-Kidney-Chip, Glomerulus (Kidney)-Chip, Collecting Duct (Kidney)-Chip. Devices, methods and systems are described for drug testing including drug transport and renal clearance. Further, such devices, methods and systems are used for determining drug-drug interactions and their effect upon renal transporter functions. Importantly, they may be used for pre-clinical and clinical drug development for treating kidney diseases and for personalized medicine.

Disclosed are living, three-dimensional tissue constructs for in vitro scientific and medical research, arrays thereof, and methods of making said tissues and arrays.

Provided are methods for isolating potent extracellular vesicle or exosome populations from mesenchymal stromal cells, and the use of the isolated extracellular vesicles or exosomes in treating vasculopathy, including pulmonary hypertension, bronchopulmonary dysplasia, and disease and conditions associated with mitochondrial dysfunction.

Provided herein are novel organoid culture media, organoid culture systems, and methods of culturing tumor organoids using the subject organoid culture media. Also provided herein are tumor organoids developed using such organoid culture systems, methods for assessing the clonal diversity of the tumor organoids, and methods for using such tumor organoids, for example, for tumor modelling and drug development applications. In particular embodiments, the tumor organoid culture media provided herein is substantially free of R-spondins (e.g., R-spondin1).

Cell based therapy comprises administration to the lung by injection into the blood system of viable, mammalian cells effective for alleviating or inhibiting pulmonary disorders. The cells may express a therapeutic transgene or the cells may be therapeutic in their own right by inducing regenerative effects.

The present invention provides a serum-free endothelial cell differentiation culture medium comprising (a) a basal culture medium and (b) an endothelial cell differentiation combination of EGF, FGF and VEGF protein, wherein the amount of EGF is higher than the amount of FGF protein. The present invention further provides a process for the preparation of cellular aggregate suspensions comprising differentiated endothelial cells from dental stem cells using the serum-free medium, as well as the use of the resulting suspension in therapy.
