  • Patent number: 11627949
    Abstract: An insertable catheter device includes a shaft including a proximal end and a distal end, an expandable balloon, and an actuator configured to expand and retract the expandable balloon. The actuator includes a fluid conduit that extends through the shaft and is coupled with the expandable balloon to enable inflation and retraction of the expandable balloon via injection or withdrawal of a fluid to or from the expandable balloon via the fluid conduit. The expandable balloon is displaceably retractable into the shaft and extendable from the shaft. A fluid pump is coupled with the fluid conduit to pump the fluid through the fluid conduit. A patch is positioned to be displaced by the expandable balloon when the expandable balloon is inflated, and the expandable balloon is displaceably retractable into the shaft and displaceably extendable from the shaft.

  • Publication number: 20210363491
    Abstract: A population of enteroendocrine cells (EEC) is obtained from a mammalian post-natal cell population, such as a population including post-natal stem cells, by treating the population with a plurality of small molecules that upregulate ChgA and promote differentiation of the cells to form the enteroendocrine cells. The upregulation of ChgA is such that the fraction of cells expressing CGA in the obtained cell population, as measured by a ChgA Immunostaining Assay, is at least about 1.5%. Small molecules that can be used to differentiate the post-natal cells into the enteroendocrine cells can include at least one of a Wnt activator, a Notch inhibitor, a Wnt inhibitor, a MEK/ERK inhibitor, a growth factor, a HDAC inhibitor, a Histone Methylation Inhibitor, a Tgf-? inhibitor, and a NeuroD1 activator. Also, the insulin expression of a population of mammalian cells is increased by treating the population with a plurality of small molecules that increase the insulin expression.

  • Publication number: 20200237852
    Abstract: Leucine-rich repeat-containing G-protein coupled receptor 5-positive (LGR5+) intestinal cells are contacted with an inhibitor of exportin 1 (XPO1), thereby producing functionally differentiated intestinal cells. The LGR5+ cells can also be contacted with a Wnt agonist. The LGR5+ cells can also be contacted with a Notch inhibitor.

  • Patent number: 10588695
    Abstract: An insertable light-dispensing catheter device, comprising a shaft including a proximal and distal end, a light guide extending through the shaft, and a mirror displaceably extendable from the catheter into a position where the mirror receives and reflects light emitted from the light guide. The mirror can be in the form of a coating on an inflatable balloon; and the balloon, when inflated, can press a patch against a defect (e.g., a ventricular septical defect), while the light cures an adhesive that binds the patch to the structure with the defect, thereby remedying the defect.

  • Patent number: 10041046
    Abstract: Described are cell culture solutions and systems for epithelial stem cell and organoid cultures, formation of epithelial constructs and uses of the same in transplantation. A single layer of epithelial cells that actively self-renews and is organized into crypts and villi clothes the intestine. It has been recently shown that the renewal of intestinal epithelium is driven by Lgr5+ intestinal stem cells (ISC) that reside at the base of these crypts (Barker et al., 2007). Lgr5+ stem cells can be isolated and cultured in vitro to form organoids containing crypt-vcllus structures that recapitulates the native intestinal epithelium (Sato et al., 2009).
