  • Publication number: 20110243898
    Abstract: Provided are methods for producing a reprogrammed fibroblast. The methods can include growing a plurality of fibroblasts in monolayer culture to confluency; and disrupting the monolayer culture to place at least a fraction of the plurality of fibroblasts into suspension culture under conditions sufficient to form one or more embryoid body-like spheres, wherein the one or more embryoid body-like spheres comprise one or more reprogrammed fibroblasts that express one or more markers not expressed by a fibroblast growing in the monolayer culture prior to the disrupting step. Also provided are reprogrammed fibroblasts produced by the disclosed methods, formulations that include reprogrammed fibroblasts, and methods for treating an injury to a tissue in a subject by administering to a subject in need thereof a composition of reprogrammed fibroblast cells in a pharmaceutically acceptable carrier.

  • Patent number: 8015897
    Abstract: A damper for shafts includes an elastomeric ring having a plurality of holes therethrough and an inertia ring having two portions such that the portions encapsulate the elastomeric ring and secure the elastomeric ring in a position. The inertia ring includes openings corresponding to the plurality of holes in the elastomeric ring. A first housing portion configured to receive first fasteners through a first set of openings in the elastomeric ring and the inertia ring to secure the first housing portion to a second housing portion. The first and second housing portions form a surface to receive an inner portion of the elastomeric ring such that the inertia ring floats on the elastomeric ring without the inertia ring contacting the first and second housing portions.
