  • Patent number: 7824671
    Abstract: The present invention relates to a composition for implantation in the subretinal space of an eye, the composition including amniotic membrane, which may be cryopreserved human amniotic membrane, and a plurality of retinal pigment epithelial (RPE) cells or RPE equivalent cells present at the amniotic membrane. The amniotic membrane may be intact, epithelially denuded, or otherwise treated. The invention includes the use of amniotic membrane for the culturing of RPE cells thereon, forming a surgical graft for replacement of Bruch's membrane as a substrate, and for the transplanting of RPE cells to the subretinal space. The composition does not elicit immunological reactions to alloantigens or to RPE specific autoantigens; and exerts anti-inflammatory, and angiogentic, and anti-scarring effects. The invention includes methods and kits for making or using composites including amniotic membrane and RPE cells. Also disclosed is a device for harvesting RPE cells.

  • Publication number: 20100003299
    Abstract: Described herein are methods and compositions for stimulating proliferation of cells that express adherent junctions and cease proliferation, for example, human corneal endothelial cells, by downregulation of certain cell-cell junctions. In one embodiment, downregulation is achieved using RNA interference, and contacting the cells with mitogenic growth factors and an agent that elevates intracytoplasmic cAMP. Furthermore, described herein are methods of isolating human corneal endothelial cells from keratocytes, and methods of preserving and maintaining viability of human corneal endothelial cell aggregates. Also described are surgical grafts comprising human corneal endothelial cells that have been isolated, optionally stored, and transiently contacted with an agent that downregulates expression of p 120, and a biocompatible support.

  • Patent number: 7494802
    Abstract: The present invention relates to a biopolymer covering for a tissue surface including, for example, a dressing, a bandage, a drape such as a bandage contact lens, a composition or covering to protect tissue, a covering to prevent adhesions, to exclude bacteria, to inhibit bacterial activity, or to promote healing or growth of tissue. An example of such a composition is an amniotic membrane covering for an ocular surface. Use of a covering for a tissue surface according to the invention eliminates the need for suturing. The invention also includes devices facilitating the fastening of a membrane to a support, culture inserts, compositions, methods, and kits for making and using coverings for a tissue surface and culture inserts. Compositions according to the invention may include cells grown on a membrane or attached to a membrane, and such compositions may be used as scaffolds for tissue engineering or tissue grafts.

  • Publication number: 20070128719
    Abstract: Described are methods for isolating/purifying and expanding animal stem cells and stem-cell-like cells. Isolation methods include conditions comprising preferentially digesting non-stem cells and non-stem-cell-like cells in a population and preferentially adhering stem cells and stem-cell-like cells in a population. Expansion methods include culturing such cells under conditions comprising modulation of TGF-? signaling, inhibition of cell signaling mediated by p38 MAP kinase using small molecular weight inhibitors, expansion of the cells on human amniotic epithelial cells as feeder layers, control of cell seeding density, control of levels of Ca2+ in the culture media, rapid adhesion on a substrate or by a combination of such conditions. More particularly, what is disclosed relates to methods and systems for expanding animal cells in ex vivo cell cultures, while preventing cellular differentiation, and selectively enriching stem cells.
