Scaffold For Nasal Tissue Engineering
A nasal tissue implant for reconstruction and tissue engineering of nasal tissue in a subject includes a tissue scaffold component comprising a biocompatible polymeric material having a plurality of open pores configured to support cell growth. The tissue scaffold component conforms to a portion of the subject's nasal region and defines at least a portion of the subject's nasal anatomy. A method of making an implantable nasal tissue implant for reconstructing a portion of a nasal anatomy of a human or other animal subject is also provided that includes laser sintering or three-dimensional (3D) printing a biocompatible polymeric material to form a tissue scaffold component comprising a biocompatible polymeric material having a plurality of open pores configured to support cell growth. Again, the tissue scaffold component substantially conforms to a nasal region specific to the human or other animal subject.
Multi-layer skin substitute products and methods of making and using the same
Provided are live, artificial, skin substitute products and methods of making and using the same, such as for wound treatment and compound testing, including compound testing for efficacy, toxicity, penetration, irritation and/or metabolism testing of drug candidates or compositions such as cosmetics.
Use of Resected Liver Serum for Whole Liver-Engineering
The disclosure provides a method of using blood or fractions thereof, e.g., serum, obtained from a mammal subjected to liver surgery, for example, obtained following a partial hepatectomy, to increase the engraftment, proliferation and/or functionality of cells on a biocompatible scaffold.
Scaffold-free 3D bioprinting of porcine cells
Provided herein are synthetic, three-dimensional (3D) bioprinted tissue constructs comprising porcine cells and methods of producing and using the same. The synthetic 3D bioprinted tissue constructs are fabricated by bioprinting spheroids comprising porcine cells, including genetically engineered cells, on a microneedle mold and fusing the spheroids to form an engineered tissue construct. Also provided are methods of using scaffold-free 3D bioprinted tissue constructs for applications related to drug screening and toxicity screening.
In-situ intervertebral fusion device and method
An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.
Patch graft compositions for cell engraftment
Compositions and methods of transplanting cells by grafting strategies into solid organs (especially internal organs) are provided. These methods and compositions can be used to repair diseased organs or to establish models of disease states in experimental hosts. The method involves attachment onto the surface of a tissue or organ, a patch graft, a “bandaid-like” covering, containing epithelial cells with supporting early lineage stage mesenchymal cells. The cells are incorporated into soft gel-forming biomaterials prepared under serum-free, defined conditions comprised of nutrients, lipids, vitamins, and regulatory signals that collectively support stemness of the donor cells. The graft is covered with a biodegradable, biocompatible, bioresorbable backing used to affix the graft to the target site. The cells in the graft migrate into and throughout the tissue such that within a couple of weeks they are uniformly dispersed within the recipient (host) tissue. The mechanisms by which engraftment and integration of donor cells into the organ or tissue involve multiple membrane-associated and secreted forms of MMPs.
