71 results about "Apoptosis Inhibitor" patented technology

Disclosed herein are compositions and methods for increasing the longevity of a cell culture and permitting the increased production of proteins, preferably recombinant proteins, such as antibodies, peptides, enzymes, growth factors, interleukins, interferons, hormones, and vaccines. By transfecting cells in culture with an apoptosis-inhibiting gene or vector, cells in culture can survive longer, resulting in extension of the state and yield of protein biosynthesis. Expression of the apoptosis-inhibitor within the cells, because it does not kill the cells, allows the cells, or an increased fraction thereof, to be maintained in culture for longer periods. This invention then allows for controlled, enhanced protein production of cell lines for commercial and research uses, particularly the enhanced production of growth factors, interferons, interleukins, hormones, enzymes, and monoclonal antibodies, and the like. The method preferentially involves eukaryotic cells in culture, and more advantageously mammalian cells in culture.

The present invention provides improved compositions and methods for the collection of stem cells from an organ, e.g., placenta. The invention provides a stem cell collection composition comprising an apoptosis inhibitor and, optionally, an enzyme such as a protease or mucolytic enzyme, vasodilator, necrosis inhibitor, oxygen-carrying perfluorocarbon, or an organ preserving compound. The invention provides methods of using the stem cell collection composition to collect stem cells and to preserve populations of stem cells.

The present invention generally relates to devices and methods for the preservation of cells using drying, freezing, and other related techniques. In one set of embodiments, the invention allows for the preservation of cells in a dried state. In another set of embodiments, the invention allows for the preservation of cells within a glass or other non-viscous, non-frozen media. In some embodiments, the invention allows for the preservation of cells at temperatures below the freezing point of water, and in some cases at cryogenic temperatures, without inducing ice formation. The cells, in certain embodiments, may be preserved in the presence of intracellular and / or extracellular carbohydrates (which may be the same or different), for example, trehalose and sucrose. Carbohydrates may be transported intracellularly by any suitable technique, for example, using microinjection, or through non-microinjected methods such as through pore-forming proteins, electroporation, heat shock, etc. In certain instances, the glass transition temperature of the cells may be raised, e.g., by transporting a carbohydrate intracellularly. In some cases, the cells may be dried and / or stored, for example, in a substantially moisture-saturated environment or a desiccating environment. The cells may also be stored in a vacuum or a partial vacuum. The cells may be protected from oxygen, moisture, and / or light during storage. In certain cases, an inhibitor, such as a cell death inhibitor, a protease inhibitor, an apoptosis inhibitor, and / or an oxidative stress inhibitor may be used during preservation of the cells. The cells may be stored for any length of time, then recovered to a viable state, e.g., through rehydration, for further use.

Provided are methods and compositions for maintaining the viability of retinal ganglion cells in a subject with an ocular disorder including, for example, glaucoma and optic nerve injury. The viability of the retinal ganglion cells can be preserved by administering a necrosis inhibitor either alone or in combination with an apoptosis inhibitor to a subject having an eye with the ocular condition. The compositions, when administered, maintain the viability of the cells and / or promote axon regeneration, thereby minimizing the loss of vision or visual function associated with the ocular disorder.
