Abstract: The invention relates to a cell sheet construct for neurovascular reconstruction. The cell sheet construct has a vascular endothelial cell layer and a neural stem cell layer, and the two layers are physically in direct contact with each other, where the vascular endothelial cell layer forms branching vasculatures, and the neural stem cell layer differentiates into neurons. The invention also relates to a method for manufacturing the cell sheet construct, having the following steps: culturing vascular endothelial cells on a substrate to form a vascular endothelial cell layer, seeding neural stem cells on the vascular endothelial cell layer to make the neural stem cells be physically in direct contact with the vascular endothelial cell layer, and culturing the neural stem cells and the vascular endothelial cell layer to differentiate into neurons and branching vasculatures to form a cell sheet construct.

Abstract: Provided is a method for producing a liquid medium composition, including using a junction conduit structure 10 having a structure in which a first inlet conduit 11 and a second inlet conduit 12 are joined together to form an outlet conduit 13, and flowing a first liquid 1 containing a particular compound into the first inflow conduit 11 and flowing a second liquid 2 containing a linking substance into the second inlet conduit 12, and allowing the flows of the both liquids to join together to mix the both liquids, thus forming a liquid medium composition 3 containing structures formed by the particular compound linked via the linking substance dispersed therein while being flown through the outlet conduit 13.
Abstract: The present disclosure provides a system, including methods and apparatus, for culturing, monitoring, and/or analyzing organoids. In an exemplary method of organoid culture, the method may comprise disposing a scaffold in a receptacle having an open side. A sealing member may be bonded to the open side of the receptacle to create a chamber. An organoid may be formed in the chamber using the scaffold. Fluid and/or at least one substance may be introduced into the chamber from an overlying reservoir for contact with the organoid.

Abstract: A method for estimating portal blood flow and hepatic function in a subject is provided. In one example, the STAT test is an in vitro simplified, convenient test intended for screening purposes that can reasonably estimate the portal blood flow from a single blood sample taken 60 minutes after orally administered deuterated-cholate. The test can be administered to a patient having, or suspected of having, Chronic Hepatitis C, Primary Sclerosing Cholangitis (PSC), Non-Alcoholic Fatty Liver Disease (NAFLD), or any chronic liver disease.

Abstract: Methods and devices are disclosed for processing stromal precursor cells (i.e., cells which can differentiate into connective tissue cells, such as in muscles, ligaments, or tendons) which can be obtained from fatty tissue extracts obtained via liposuction. Normal processing of a liposuction extract involves centrifugation, to concentrate the stromal cells into a semi-concentrated form called “spun fat”. That “spun fat” can then be treated by mechanical processing (such as pressure-driven extrusion through 0.5 mm holes) under conditions which can gently pry the stromal cells away from extra-cellular collagen fibers and other debris in the “spun fat”. The extruded mixture is then centrifuged again, to separate a highly-enriched population of stromal cells which is suited for injection back into the patient (along with platelet cells, if desired, to further promote tissue repair or regeneration).
Abstract: Nanostraws and to methods of utilizing them in order to deliver biologically relevant molecules such as DNA, RNA, proteins etc., into non-adherent cells such as immune cells, embryos, plant cells, bacteria, yeast etc. The methods described herein are repeatedly capable of delivering biologically relevant cargo into non-adherent cells, with high cell viability, dosage control, unaffected proliferation or cellular development, and with high efficiency. Among other uses, these new delivery methods will allow to scale pre-clinical cell reprogramming techniques to clinical applications.
