Abstract: Provided herein are compositions, methods, and kits for proliferating muscle cells by exposing the muscle cells to a prostaglandin E2 (PGE2) compound or compound that activates PGE2 signaling. Also provided are methods for regenerating muscle in a subject suffering from muscular atrophy, dystrophy, and/or injury by administering a PGE2 compound alone or in combination with isolated muscle cells. The PGE2 compound in combination with the isolated muscle cells can be administered prophylactically to prevent a muscle disease or condition.

Abstract: Methods are provided for producing cells within a lineage (lineage restricted cells) from post-mitotic differentiated cells of the same lineage ex vivo and in vivo, and for treating a subject in need of tissue regeneration therapy by employing these lineage-restricted cells. In addition, the production of lineage restricted cells from postmitotic tissues derived from patients with diseases allows for a characterization of pathways that have gone awry in these diseases and for screening of drugs that will ameliorate or correct the defects as a means of novel drug discovery. Also provided are kits for performing these methods.

Abstract: Methods and compositions are provided for detecting molecular translocations, particularly protein translocations within and between sub-cellular compartments, using at least two components that exhibit a localization-dependent difference in complementation activity. In particular, alpha-complementing ?-galactosidase fragments are provided. These ?-galactosidase reporter fragments display significantly enhanced enzymatic activity when one fragment is localized in a membrane. Methods for carrying out no-wash ELISA assays based on the reporter component system are also provided.

Abstract: Compounds and compositions for the transient expression of exogenous telomerase activity in a cell are provided. The compounds and compositions, which relate to a ribonucleic acid coding for a telomerase reverse transcriptase, are useful in the extension of telomeres in cells needing such treatment. Such cells include, for example, cells that contain shortened telomeres and cells from subjects that may benefit from telomere extension, for example subjects that suffer from, or are at risk of suffering from, age-related or other illnesses. Also provided are methods of extending telomeres through the administration of the provided compounds and compositions to animal cells, either in vitro or in vivo, and kits including the compounds or compositions and instructions for use.
