    摘要: The present invention provides compositions for the controlled delivery of compounds into cells. Entry of the compound into a cell is mediated by a cell penetrating peptide capable of translocating the compound across a cell membrane. An inhibitor of cell penetrating peptide, which activity is regulatable by action of a protease, serves to limit delivery of the compound to cells and tissues having the protease activity.

    摘要: Disclosed is a method of transdifferentiating an epidermal basal cell into a cell having one or more morphological, physiological and/or immunological features of a neural progenitor, neuronal, or glial cell by culturing a proliferating epidermal basal cell population derived from the skin of a mammalian subject; exposing the epidermal basal cell(s) to an antagonist of bone morphogenetic protein (BMP), such as fetuin, noggin, chordin, gremlin, or follistatin; and growing the cell(s) in the presence of at least one antisense oligonucleotide comprising a segment of a human MSX1 gene and/or a segment of a human HES1 gene, or homologous non-human counterpart of either of these. Also disclosed is a transdifferentiated cell of epidermal origin and cell cultures derived therefrom. In addition, methods of using the inventive transdifferentiated cell(s) and cell cultures to identify a novel nerve growth factor or to screen a potential chemotherapeutic agent by detecting the presence or absence of an effect, in vitro, on a morphological, physiological and/or molecular biological property of the transdifferentiated cell(s) are described, as is a method of using the transdifferentiated cell(s) and cell cultures to screen a potential chemotherapeutic agent to treat a nervous system disorder of genetic origin. A kit useful for practicing the methods is disclosed

    摘要: A method is provided for inducing DNA synthesis in differentiated neurons. According to certain embodiments of the invention, a method for inducing DNA synthesis in a differentiated neuron is provided that includes obtaining a vector comprising nucleic acid encoding an E2F regulator and/or an E1A regulator, wherein the vector can be used to express the nucleic acid in a differentiated neuron, and transfecting a differentiated neuron with the vector. According to certain embodiments of the invention, a method for integrating DNA encoding a desired protein in a differentiated neuron is provided that includes obtaining a vector comprising nucleic acid encoding an E2F regulator and/or an E1A regulator, wherein the vector can be used to express the nucleic acid in a neuron, obtaining DNA encoding a desired protein, and cotransfecting a differentiated neuron with the vector and the DNA encoding the desired protein such that the DNA encoding the desired protein is integrated in the differentiated neuron and the desired protein is produced.
