摘要:
A method and a device (10) for reorganizing the fibers of a matrix in a living tissue sheet (S) by inducing controlled mechanical constraints in the living tissue (S) sheet thus causing the fibers of the matrix to be aligned parallel to the strain orientation. The sheet (S) is held in a stretched state until the fibers set in place.
摘要:
The present invention relates to tissues and tissue sheets assembled from adipose-derived stromal cells. Particularly, it relates to reconstructed adipose tissues which comprise adipocytes as well as reconstructed conjunctive tissues which comprise adipose-derived stromal cells. The reconstructed tissues and sheets can be used, for example, in cosmetic applications for the replacement or addition of soft tissues, in pharmacological and toxicological applications for the in vitro testing of small molecules or cosmetic products as well as in therapeutic applications for the delivery of agents.
摘要:
A contractile smooth muscle cell construct and a method for preparing the smooth muscle cell construct are described. The smooth muscle cell construct is comprised of (i) smooth muscle cells that have been cultured in vitro under conditions to allow the formation of a sheet of smooth muscle cells and (ii) an endogenous fibrous matrix formed by the smooth muscle cells, wherein the smooth muscle cell construct retains the ability to contract in response to vasoactive agonists. The smooth muscle cell construct may be prepared in planar or tubular form and can be used to study or evaluate the contractile responses of smooth muscle cells.
