Abstract: The invention is compositions of extracellular matrix that comprise mammalian extracellular matrix from two or more tissue sources in a mammal. The invention also includes methods of using these compositions to regenerate tissue or generate new tissue at sites of defects or wounds in mammals.

Abstract: The invention is articles of layered sheets or balled strips or pieces of extracellular matrix for forming breast implants for augmenting or reconstructing breast tissue in humans. The invention is also to methods of using these in implant articles to augment or reconstruct a human breast.

Abstract: The invention is compositions of extracellular matrix that comprise mammalian extracellular matrix from two or more tissue sources in a mammal. The invention also includes methods of using these compositions to regenerate tissue or generate new tissue at sites of defects or wounds in mammals.

Abstract: The invention is articles and compositions of extracellular matrix for forming breast implants and otherwise augmenting or reconstructing breast tissue and other cosmetically desired tissue in humans, such as lips and cheeks. The invention is also to methods of using these in implant articles to augment or reconstruct a human breast or other tissue.

Abstract: The invention an article or composition of mammalian extracellular matrix (ECM) for placement in a lumpectomy space of a breast after tumor removal. The extracellular matrix article or composition can regenerate lost breast tissue, reduce the formation of scar tissue at the site of excision, and reduce a likelihood of local tumor recurrence at the lumpectomy site. The article can be sheet ECM, and the composition can be particulate ECM or emulsion or gel ECM.

Abstract: The invention is to a method of recruiting stem cells to a site of malignancy by contacting the site with exogenous mammalian extracellular matrix in the form of a sheet article, or a composition comprising particulate extracellular matrix, or emulsion or gel extracellular matrix.

Abstract: The invention is a method of treating ovarian cancer by contacting a post-surgical site of an ovarian cancer patient with a composition or a sheet article comprising extracellular matrix to inhibit cancer cell attachment, promote wound healing after the surgery, reduce scar formation at the surgical site, regenerate lost tissue, and prevent tumor recurrence at the site or in the peritoneum generally.

Abstract: Methods are described for using exogenous extracellular matrix (ECM) to fill a space created after cancerous tumor excision. The extracellular matrix promotes healing at the tumor excision site. Forms of ECM that can be used include exogenous mammalian ECM in sheets, particulate and emulsion.

Abstract: The invention is compositions and methods for inhibiting growth of an abnormally proliferating cell in a mammal; methods include inhibiting growth of abnormally proliferating cells after tumor resection, and methods of recruiting stem cells to a site of malignancy; compositions include liquid or semi-solid extracellular matrix compositions having specified concentrations of extracellular matrix.
