Abstract:
A method of making a three-dimensional microtissue comprising the reaction of at least two cytocompatible polymer solutions, each polymer comprising complementary reactive groups capable of spontaneous reaction, at least one of which solutions additionally contains cells. The method allows the rapid, efficient production of microtissues useful for purposes such as pharmaceutical screening and tissue reconstruction.
Abstract:
The invention relates to animal models, and in particular to novel ex-vivo animal models for investigating the underlying mechanisms occurring in neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease or Motor Neurone Disease. The invention extends to apparatus, methods and assays for providing such models, as well as for testing pharmacological compounds, which may regulate neurological processes, and for drug screening for use in treating neurodegenerative disease. The invention also relates to novel polypeptides, peptidomimetics and compositions, for use in the assays and apparatus used to investigate neurodegenerative disorders, and for drug screening. The invention also relates to apparatus and methods for animal models for investigating neuroregeneration.
Abstract:
The invention relates to a method for evaluating whether a molecule of interest binds or is incorporated in at least one target tissue, comprising visualizing and comparing the distribution of the molecule of interest and of at least one control compound within the target tissue or on the target tissue surface of at least one animal that has previously received the molecule of interest and/or the control compound. Advantageously, the distribution of the molecule of interest is visualized and compared with the distribution of positive and negative compounds using mass spectrometry imaging on the surface of the target tissue.
Abstract:
An extrudable hydrogel composition useful for making a three-dimensional organ construct includes a cross-linkable prepolymer, a post-deposition crosslinking group, optionally, an initiator that catalyzes the reaction between the prepolymer and said the crosslinking group; live cells (e.g., plant, animal, or microbial cells), optionally at least one one growth factor, and optionally water to balance. Methods of using the same and products so made are also described.
Abstract:
The present invention relates to a method for producing a contractile cellular construct, comprising the steps of: a) seeding pre-selected cells onto a mold, wherein the pre-selected cells comprise signal emitting agents; and b) culturing the pre-selected cells to produce the cellular construct. The said method is exemplified by mixing cardiomyocytes with fluorescent microbeads, seeding the suspension on a polydimethylsiloxane (PDMS) mold and culturing to form a contractile device comprising of cardiac muscles. The present invention also relates to a method for measuring the contractility of the cellular construct by measuring the displacement of the signal emitting agents, and a method for screening a method for screening one or more agents for modulating the contractility of a contractile cellular construct.
Abstract:
The present invention relates to organoids derived from a single cell, such as a prostate cancer cell, and methods and compositions relating to the production and use thereof, including cell culture medium for producing organoids and methods of personalized treatment for prostate cancer. The invention further provides a humanized mouse comprising a prostate organoid derived from a patient's prostate cell.
Abstract:
Provided herein are methods for evaluating the effect of 2-(tert-butylamino)-4-((1R,3R,4R)-3-hydroxy-4-methylcyclohexylamino)-pyrimidine-5-carboxamide or a pharmaceutically acceptable stereoisomer, tautomer, solid form, polymorph, salt, hydrate, clathrate, or solvate thereof in a patient with an assay based on UVB-irradiation and phosphorylated c-Jun expression. The analyzes allow for evaluation of dose-response and identification of patient populations who are sensitive to 2-(tert-butylamino)-4-((1R,3R,4R)-3-hydroxy-4-methylcyclohexylamino)-pyrimidine-5-carboxamide or a pharmaceutically acceptable stereoisomer, tautomer, solid form, polymorph, salt, hydrate, clathrate, or solvate thereof.
Abstract:
A method of producing a synthetic skin comprising depositing a curable polymer on a non-biological material having a rough surface, curing the polymer and then removing the non-biological material from the cured polymer to provide a synthetic skin. The rough surface is imprinted onto the polymer and may be an abrasive surface such as sandpaper of various coarse grades. The rough surface may be pre-coated with a non-stick substance such as silicon dioxide liquid glass. The curable polymer is preferably silicone. The resulting synthetic skin may have hair embedded into it and may be used as a physical model for the testing of chemical agents.
