    摘要: Methods to pattern substrates with dense periodic nanostructures that combine top-down lithographic tools and self-assembling block copolymer materials are provided. According to various embodiments, the methods involve chemically patterning a substrate, depositing a block copolymer film on the chemically patterned imaging layer, and allowing the block copolymer to self-assemble in the presence of the chemically patterned substrate, thereby producing a pattern in the block copolymer film that is improved over the substrate pattern in terms feature size, shape, and uniformity, as well as regular spacing between arrays of features and between the features within each array compared to the substrate pattern. In certain embodiments, the density and total number of pattern features in the block copolymer film is also increased. High density and quality nanoimprint templates and other nanopatterned structures are also provided.

    摘要: Methods of generating p63-positive cells from embryoid bodies and pluripotent cells by culturing the cells in the presence of a retinoid and optionally a bone morphogenetic protein, such that the cells express at least p63. The p63-positive cells can be further cultured without the retinoid and optional bone morphogenetic protein to K14-positive cells. The K14-positive cells can be further cultured into various terminally differentiated cell types of the epithelial lineage.
