  • Publication number: 20230338617
    Abstract: Methods and compositions for the biological repair of cartilage using a hybrid construct combining both an inert structure and living core are described. The inert structure is intended to act not only as a delivery system to feed and grow a living core component, but also as an inducer of cell differentiation. The inert structure comprises concentric internal and external and inflatable/expandable balloon-like bio-polymers. The living core comprises the cell-matrix construct comprised of HDFs, for example, seeded in a scaffold. The method comprises surgically removing a damaged cartilage from a patient and inserting the hybrid construct into the cavity generated after the foregoing surgical intervention. The balloons of the inert structure are successively inflated within the target area, such as a joint, for example. Also disclosed herein are methods for growing and differentiating human fibroblasts into chondrocyte-like cells via mechanical strain.

  • Publication number: 20130315908
    Abstract: The present invention generally concerns the detection and/or treatment of aneurysm in a non-invasive manner. In particular cases, the invention concerns methods and compositions for localizing a labeled composition to the site of an aneurysm for its detection and, in further cases, treatment of the aneurysm. In specific cases, the composition targets a subendothelial component of the aneurysmal wall, such as a smooth muscle cell exposed at the luminal surface of the vessel. In further specific cases, the composition targets an integrin receptor or laminin.
