  • 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.

  • 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.
