Patents by Inventor Anat Perets

Anat Perets has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9725693
    Abstract: Methods of making a biologically active three-dimensional scaffold capable of supporting growth and differentiation of a cell are described. Biologically active three-dimensional scaffold made by the methods of the invention and an engineered tissue made from the scaffolds are described. Fibers of desired porosity can be obtained from non-structural ECM by lyophilization and/or electrospinning which can be useful for numerous tissue engineering applications requiring complex scaffolds, such as wound healing, artificial skin (burns), soft tissue replacement/repair and spinal cord injury.
    Type: Grant

  • Publication number: 20150359619
    Abstract: The present invention relates to a hybrid graft and methods of generating the hybrid graft. The hybrid graft comprises an exterior surface and a luminal surface. The luminal surface comprises a micropattern of grooves to which cells adhere and orient along. The exterior surface comprises electrospun microfibers wherein the microfibers provide mechanical properties to the graft. The hybrid graft is capable supporting endothelial cell attachment, endothelial cell alignment, cell proliferation, and maintaining their in vivo function. The graft of the invention can recapitulate the in vivo morphology and function of natural vascular endothelium.

  • Patent number: 7214371
    Abstract: The invention is directed to tissue-engineered biografts, methods for preparing the biografts of the invention, and methods for repairing a damaged myocardium in a mammal. The methods of the invention can include providing a three-dimensional porous polysaccharide matrix; introducing mammalian cells into said matrix; growing said cells in said matrix in vitro, until a tissue-engineered biograft is formed; and transplanting the tissue-engineered biograft onto myocardial tissue or myocardial scar tissue of said mammal. The tissue-engineered biograft of the invention can form a contracting tissue. The methods of the invention can optionally include removing scar tissue or dead tissue from the site of implantation prior to transplanting the biograft.
