  • Patent number: 9636362
    Abstract: Compositions and methods are provided for the manufacture and use of a pullulan-based collagen hydrogel film with controlled porosity. The hydrogel is fabricated with salt-induced phase inversion and cross-linking to form a reticular scaffold. This soft collagen scaffold displays excellent handling characteristics, durability, and a porous dermal-like ultrastructure that is maintained in vitro. Cells, including cells involved in tissue repair, are viably sustained within the scaffold. The hydrogel films are biodegradable, and find particular use in wound healing, where the hydrogel scaffold can be replaced by dermal cells over time.

  • Patent number: 9403895
    Abstract: Improved methods are provided for the recombinant synthesis of collagen, particularly collagen VII, in host cell, and for therapeutic delivery of the same. The recombinant collagen is produced in a host cell that has increased levels of prolyl-4-hydroxylase, relative to basal cell levels. The collagen produced by the methods of the invention has increased numbers of modified proline residues, relative to a recombinant collagen produced in a host cell having basal levels of prolyl-4-hydroxylase. The increased proline modification provides for a collagen having increased stability, including increased in vivo stability.

  • Publication number: 20160102288
    Abstract: Efficient stem cell delivery into biomaterials using capillary driven encapsulation are disclosed herein where stem/progenitor and/or tissue specific cells are rapidly and efficiently seeded via capillary driven encapsulation into a porous scaffold for cell deliver in the skin or any other organ. The rapid capillary force approach maximizes both seeding time and efficiency by combining hydrophobic, entropic and capillary forces to promote active, ‘bottom-up’ cell engraftment. This methodology uses micro domain patterned biopolymers in a porous dry gel to generate capillary pressure to move a viscous stem cell mix from a hydrophobic reservoir into the polymer matrix to promote active cell seeding within the entire gel volume.

  • Patent number: 9283289
    Abstract: Encompassed are pharmaceutically acceptable compositions formulated for the topical or transdermal delivery of probes specific for cyclooxygenase-2 (COX-2) of human and non-human subjects. In particular, an activatable probe comprises a fluorescent moiety comprising a fluorophore attached to a compound having selective affinity for COX-2, and a removable fluorescence quencher linked to the fluorescent moiety by a cleavable linker. Upon delivery to a recipient subject, the activatable probe is localized and concentrated in tissues and cells with elevated levels of COX-2. The linker is cleaved to release the fluorescence quencher.

  • Publication number: 20160058705
    Abstract: Compositions and methods for treating cardiovascular and pulmonary diseases and disorders with apelin are disclosed. In particular, the invention relates to formulations comprising apelin encapsulated in liposome nanocarriers conjugated with polyethylene glycol (PEG) and their use in treatment of cardiovascular and pulmonary diseases and disorders. Encapsulation of apelin in PEG-conjugated liposomes significantly enhances efficacy, improves cellular uptake of apelin, and allows for sustained and extended release of apelin under physiological conditions.

  • Publication number: 20160058377
    Abstract: A method of testing for specificity and strength of an allergic reaction is performed by penetrating the skin of an individual with the microneedle array comprising a plurality of epitopes and determining the response of the skin to the allergens. The response can be measured with a thermal imaging device. Analysis, and optionally treatment, can be provided to the individual.

  • Publication number: 20160030510
    Abstract: Methods of treating Alzheimer's disease and other tauopathies are disclosed. In particular, the invention relates to methods of treating Alzheimer's disease and other tauopathies with inhibitors of microtubule affinity regulating kinase (MARK). Hyperphosphorylation of tau by MARK is associated with the pathogenic deposition of intracellular neurofibrillary tangles and loss of synaptic markers, dendritic spines, and synapses during progression of Alzheimer's disease and other tauopathies. Peptide inhibitors derived from the Helicobacter pylori protein CagA block phosphorylation of tau in neuronal cells and thereby decrease the deposition of neurofibrillary tangles and the toxic effects of Abeta-42.
