Abstract: The present invention provides compositions and methods for wound healing and tissue regeneration. The compositions of the present invention comprise amniotic membrane of the placenta. In certain embodiments, the composition comprises amniotic membrane powder or solubilized amniotic membrane (SAM). In some aspects, the composition is cell-free and rich in cytokines, extracellular matrix proteins, and other components that improve tissue regeneration. In one aspect, the composition is a hydrogel scaffold that comprises amniotic membrane. The present invention reduces contraction and improves blood vessel development in regenerating tissue.

Abstract: Vascular scaffolds and methods of fabricating the same are disclosed for tissue engineering of vascular constructs. By combining electrospun matrices with cell sheet technologies, vascular constructs with more mature cell layers can be obtained for reconstruction of blood vessels, heart valves and the like. A engineered smooth muscle cell sheet, wrapped around an electrospun vascular scaffold, is able to provide a mature SMC layer that expresses strong cell-to-cell junction markers and contractile proteins. In addition, preconditioning of the cell sheet covered vascular scaffold maintained cell viability and infiltration into the scaffold.

Abstract: The invention is directed to methods of inducing cell recruitment and tissue regeneration at a target site in a subject. It is also based, in part, on the discovery that a subject's own biologic resources and environmental conditions can be used for in situ tissue regeneration and thereby reduce or eliminate the need for donor cell procurement and ex vivo manipulation of such donor cells. Methods are disclosed for recruitment of a subject's own stem cells to a target region by inducing a sustained positive pressure at a target site, such as the kidney, thereby increasing the number of pluripotent cells capable of differentiating to regenerate the target tissue.

Abstract: The invention is directed to methods and compositions for obtaining uniform sized muscle fiber fragments for transplantation. These muscle fiber fragments are able to reconstitute into long fibers that are oriented along native muscle. The implanted muscle cells integrate with native vascular and neural network, as confirmed by histology and immunohistochemistry. This invention is particularly advantageous because autologous muscle can be harvested from a donor site, processed and injected into target sites in the operating room. The fragmented muscle fibers can be readily integrated within the host.

Abstract: A method of making an organ or tissue comprises: (a) providing a first dispenser containing a structural support polymer and a second dispenser containing a live cell-containing composition; (b) depositing a layer on said support from said first and second dispenser, said layer comprising a structural support polymer and said cell-containing composition; and then (c) iteratively repeating said depositing step a plurality of times to form a plurality of layers one on another, with separate and discrete regions in each of said layers comprising one or the other of said support polymer or said cell-containing composition, to thereby produce provide a composite three dimensional structure containing both structural support regions and cell-containing regions. Apparatus for carrying out the method and composite products produced by the method are also described.

Abstract: A method of producing organized skeletal muscle tissue from precursor muscle cells in vitro comprises: (a) providing precursor muscle cells on a support in a tissue media; then (b) cyclically stretching and relaxing the support at least twice along a first axis during a first time period; and then (c) optionally but preferably maintaining the support in a substantially static position during a second time period; and then (d) repeating steps (b) and (c) for a number of times sufficient to enhance the functionality of the tissue formed on the support and/or produce organized skeletal muscle tissue on the solid support from the precursor muscle cells.
