Compositions and methods for delivery of hydrophobic active agents
Disclosed herein is a delivery composition for administering a hydrophobic active agent. In one embodiment, a delivery composition for local administration of a hydrophobic active agent to a tissue or organ of a patient is disclosed. In one embodiment, the delivery composition includes a cationic delivery agent, a therapeutically effective amount of a hydrophobic active agent and a pharmaceutically acceptable aqueous carrier. In one embodiment, the cationic delivery agent includes polyethyleneimine (PEI). In an embodiment, the invention includes a drug delivery device including a substrate; and coated therapeutic agent particles disposed on the substrate, the coated therapeutic agent particles comprising a particulate hydrophobic therapeutic agent; and a vinyl amine polymer. Methods of making the delivery composition, as well as kits and methods of use are also included herein.
Encapsulation of pancreatic cells derived from human pluripotent stem cells
The present invention relates to methods for encapsulating pancreatic progenitors in a biocompatible semi-permeable encapsulating device. The present invention also relates to production of human insulin in a mammal in response to glucose stimulation.
NANOFIBER-HYDROGEL COMPOSITES FOR ENHANCED SOFT TISSUE REPLACEMENT AND REGENERATION
A composite material can include a gel and at least one nanostructure disposed within the gel. A method for healing a soft tissue defect can include applying a composite material to a soft tissue defect, wherein the composite material includes a gel and a nanostructure disposed within the gel. A method for manufacturing a composite material for use in healing soft tissue defects can include providing a gel and disposing nanofibers within the gel.
CORE-SHELL STRUCTURE FOR ESTABLISHING NORMAL AND CANCER ORGANOID MICROENVIRONMENT AND FABRICATION METHOD THEREFOR
Proposed is a core-shell structure including a shell portion and a core portion, in which the shell portion includes n shells that are sequentially located from outside to inside, the core portion includes a core located inside the shell portion, n is any one of natural numbers from 1 to 30, when n is 1, the core is located adjacent to the inside of a first shell, when n is any one of natural numbers from 2 to 30, an n.sup.th shell is located adjacent to the inside of an n−1.sup.th shell, the n.sup.th shell is an empty space or is a hydrogel including at least one of an n.sup.th extracellular matrix and an n.sup.th cell, the core is an empty space or is a hydrogel including at least one of an extracellular matrix for a core and a cell for a core, two of the n shells and the core that are in contact with each other are not empty spaces simultaneously, and densities of the two of the n shells and the core that are in contact with each other are identical or different, thereby mimicking the construction of hollow organs such as the stomach, intestines, bladder, and lungs.
Microgel compositions
This invention relates to microgel compositions, and in particular, to gel compositions fanned by binding a plurality of individual microgel particles together. The present invention also relates to processes for the preparation of these compositions and their use for particular applications, especially medical applications such as the repair of damaged, degenerated or inappropriately formed load-beating tissue (such as, for example, intervertebral discs).
RHO KINASE INHIBITOR RELEASING IMPLANTS AND RELATED METHODS OF USE
The present disclosure is directed to intracameral implants for treating and/or preventing corneal disorders, diseases, and/or conditions, such as corneal endothelial dystrophies. The intracameral implants can be configured to provide a sustained release of a therapeutic agent, such as a Rho kinase inhibitor, for a prolonged period of time. The intracameral implants can include a non-bioresorbable anchor or a bioresorbable matrix.
Microgel Compositions
This invention relates to microgel compositions, and in particular, to gel compositions formed by binding a plurality of individual microgel particles together. The present invention also relates to processes for the preparation of these compositions and their use for particular applications, especially medical applications such as the repair of damaged, degenerated or inappropriately formed load-bearing tissue (such as, for example, intervertebral discs).
CELL ENCAPSULATION DEVICES AND METHODS OF USING SAME
Disclosed herein are devices for encapsulating biological cells and are suitable to be implanted into a subject. In different aspects of the disclosure, the devices may comprise a plurality of polymer layers. In one aspect, a device comprises a first polymer layer and a second polymer layer. In some cases, the first polymer layer may be a nanoporous polymer layer. In some cases, the second polymer layer may be a macroporous polymer layer. The first and second polymer layers may define a lumen for enclosing a population of cells. The devices may be used to transplant cells producing therapeutic agents into a subject (e.g., for the treatment of a disease).
MULTI-LAYERED CELL CAPSULES AND USES THEREOF
The present invention provides a hydrogel capsule comprising a cell, a protein, and a cross-linking agent; wherein the cell is within a first core layer comprising the protein; and wherein the first core layer is surrounded by a second layer comprising the protein and the cross-linking agent. The invention further provides the hydrogel capsule for use in therapy, prognosis and diagnosis, a method for culturing cells, a method for differentiating cells, and method for producing the hydrogel capsule. The hydrogel capsules of the invention are particularly useful for encapsulating pancreatic islets
Antiperspirant and deodorant compositions comprising malodor reduction compositions
The present invention relates to personal care compositions comprising malodor reduction compositions and methods of making and using such personal care compositions. Such personal care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesireable scent and when perfume is used to scent such compositions, such scent is not unduely altered by the malodor control technology.
