Abstract: Provided herein are methods for culturing cells, including stimulating or expanding (proliferating), a plurality of cells in a composition of cells such as a population of lymphocytes. In some aspects, provided methods and reagents for the culturing, such as stimulation or expansion (proliferation), of cell populations involve binding of agents to a molecule on the surface of the cells, thereby providing one or more signals to the cells. In some cases, the reagents are multimerization reagents and the one or more agents are multimerized by reversibly binding to the reagent. In some aspects, the multimerized agent can provide for expansion or proliferation or other stimulation of a population of cells, and then such stimulatory agents can be removed by disruption of the reversible bond. Also provided are compositions, apparatus and methods of use thereof.

Abstract: Provided herein are methods that relate, in some aspects, to the incubation or culturing, such as to induce stimulation of expansion (proliferation), activation, costimulation and/or survival, of a composition of cells, such as a population of lymphocytes. In some aspects, provided are methods and reagents for the stimulation, e.g., of expansion (proliferation), survival or persistence, activation, costimulation, or other effect, of cell populations that involve binding of agents to a molecule on the surface of the cells, thereby providing one or more signals to the cells. In some cases, the reagents are reagents containing a plurality of binding sites for agents, such as multimerization reagents, and thus the one or more agents are multimerized by reversibly binding to the reagent, e.g., thereby creating a stimulatory reagent (multimerized agent), having stimulatory agents multimerized thereon.

Abstract: An intervertebral implant for insertion into an intervertebral disc space between two adjacent vertebral bodies of a human or animal spine. The intervertebral implant has an implant top side, which defines a first vertebral body abutment face for abutting against a first vertebral body, and an implant bottom side, which defines a second vertebral body abutment face for abutting against a second vertebral body. The intervertebral implant comprises a frame structure with at least two support elements. The at least two support elements extend from the implant top side to the implant bottom side. The at least two support elements define support element longitudinal axes, which run transversely, in particular perpendicularly, to the first and/or second vertebral body abutment face.
