  • Patent number: 9096831
    Abstract: A method is provided to functionally select cells with enhanced characteristics relevant to cell engraftment, including both spontaneous migration and directional migration towards specific chemo-attractants. The cells are preferably undifferentiated cells, such as mesenchymal stem cells. The method involves entrapping or encapsulating the cells in a biomaterial barrier, optionally inducing cell migration, and selecting cells that migrated through the barrier. The cells selected by this method have better migratory activities and enhanced in vivo engraftment to injured tissues when they are supplemented systemically.

  • Patent number: 8877617
    Abstract: A method for forming of a thin film on a substrate is disclosed. The method includes cleaning a process chamber by flowing a first gas having fluorine. The method also includes coating the process chamber with a first encapsulating layer including amorphous silicon (A-Si) by flowing a second gas for a first duration, where the first encapsulating layer protects against fluorine contamination. The method further includes loading a substrate into the process chamber, depositing a thin film on the substrate by flowing a third gas into the process chamber and unloading the substrate from the process chamber. The thin film can include silicon nitride (SiN), the first gas can include nitrogen triflouride (NF3) gas and second gas can include silane (SiH4) gas. The thin film can be formed using plasma-enhanced chemical vapor deposition. The substrate can be a solar cell or a liquid crystal display (LCD).
