The invention relates to a buffer solution for suspending animal or human cells and for dissolving biologically active molecules in order to introduce said biologically active molecules into the cells using an electric current and to a method for introducing biologically active molecules into animal or human cells using an electric current and a buffer solution. The inventive buffer solution has a buffering capacity of at least 20 mmol*I⁻¹*pH⁻¹ and an ionic strength of at least 200 mmol*I⁻¹ during a change to the pH value from pH 7 to pH 8 and at a temperature of 25° C. The use of a buffer solution of this type in the corresponding method allows biologically active molecules to be introduced into animal and human cells with a high degree of transfection efficiency and at the same time a low cell mortality. Different cell types, in particular dormant and actively dividing cells of low activity, can be successfully transfected in said buffer solution.

The present invention provides a cell culture treatment device for culturing, treating and collecting cells, which includes a flow path, a cell-retaining section, a solution inlet, a solution outlet, a cell collection port and a lid. The present invention also provides an device for easily, efficiently separating and collecting the cells thereby in a short period of time, and provides a method therefor.

This invention provides methods and compositions for the detection, diagnosis and treatment of amyloid-associated diseases, in particular, diseases comprising deposition of amyloid assemblies, fibrils, filaments, tangles, or plaques. A preferred composition comprises monoclonal antibodies that specifically bind amyloid proteins, peptides or fragments and change the conformation.

The present invention is directed to a combination of therapeutic compounds and treatment methods and kits using the combination. In particular, one of the combination affects the NCca-ATP channel of neural tissue, including neurons, glia and blood vessels within the nervous system. Exemplary SUR1 and/or TRPM4 antagonists that inhibit the NCca-ATP channel may be employed in the combination. The combination therapy also employs one or more of a non-selective cation channel blocker and/or an antagonist of VEFG, NOS, MMP, or thrombin. Exemplary indications for the combination therapy includes the prevention, diminution, and/or treatment of injured or diseased neural tissue, including astrocytes, neurons and capillary endothelial cells, that is due to ischemia, tissue trauma, brain swelling and increased tissue pressure, or other forms of brain or spinal cord disease or injury, for example. In other embodiments, there are methods and compositions directed to antagonists of TRPM4, including at least for therapeutic treatment of traumatic brain injury, cerebral ischemia, central nervous system (CNS) damage, peripheral nervous system (PNS) damage, cerebral hypoxia, or edema, for example.

The invention provides devices, compositions and methods for maintaining conditions in a cell culture and for measurement of conditions in the cell culture. In particular, the invention provides hydrogel materials, apparatus and methods for several non-invasive techniques of maintaining glucose and pH levels in cell cultures at near-optimal levels and the non-invasive measurement of pH levels in cell cultures.

The invention provides small molecule mimics of the Smac peptide that are dimers or dimer-like compounds having two binding domains connected by a linker These compounds are useful to promote apoptosis. The invention includes pharmaceutical compositions comprising such compounds and methods to use them to treat conditions including cancer and autoimmune disorders.

The invention features compositions comprising agents having cardiac protective activity isolated from epicardial progenitor cells and derivatives thereof, and methods for the use of such compositions.

The present invention provides methods to prevent photoreceptor death. In particular, the present invention provides peptides which prevent FAS-mediated photoreceptor apoptosis.

The invention features compositions comprising mesenchymal stem cells or multipotent stromal cells, agents secreted by such cells in culture, and methods featuring such cells for the repair or regeneration of a damaged tissue or organ. The present invention is based, at least in part, on the discovery that agents secreted by bone marrow mesenchymal stem cells or multipotent stromal cells (MSCs) were useful for the treatment or prevention of tissue damage related to ischemic injury (e.g., cerebral or cardiac ischemia).

The invention features methods for decreasing necrosis. The invention also features methods for treating a subject with a condition in which necrosis occurs. The invention further features chemical compounds used to decrease necrosis.

Provided are methods and compositions for treating ocular conditions characterized by the presence of unwanted choroidal neovasculature, for example, neovascular age-related macular degeneration. The selectivity and sensitivity of, for example, a photodynamic therapy (PDT)-based approach can be enhanced by combining the PDT with an anti-FasL factor, for example, an anti-FasL neutralizing antibody.

Disclosed are cellular compositions and methods for preventing, treating or reducing the severity of tissue ischemia, particularly limb ischemia in a mammal. One inventive method includes administering a therapeutically effective amount of a cellular composition comprising a novel isolated multi-potent human bone marrow-derived stem cell (BMSC) having undetectable or negligible levels of markers of other known stem cells isolated from bone marrow. These cells can be expanded in vitro and formulated into cellular compositions and grafts capable of differentiating into components of functional new blood vessels when directly administered into ischemic limb tissue.
