  • Publication number: 20240280262
    Abstract: A sleeve made of rigid tube into which the feed lines for feeding the waste to treated and the gases to be discharged lead. In order to avoid contamination or blockage of the sleeve, a tool for scraping the inner face of the wall thereof is added, in this case a terminal tubular section of one of the feed lines, which carries out orbital movements tangent to this inner face. Various cooling, rinsing and overpressure structures are added, as is a docking device extending at the bottom of the sleeve for connecting the latter to the heat treatment container.

  • Publication number: 20220389376
    Abstract: The present invention provides a method for reprogramming a human somatic cell to a cell exhibiting at least one characteristic of a trophoblast stem cell (TSC), the method comprising the following steps in order: a) increasing the protein expression of one or more factors in the somatic cell, wherein the factors are for reprogramming the somatic cell towards a pluripotent state; b) culturing the cell for a sufficient time and under conditions to allow the reprogramming of the cell towards a pluripotent state; c) contacting the cell with a culture medium suitable for sustaining trophoblast stem cells (TSC); and d) culturing the cell in the TSC medium for a sufficient time and under conditions to allow the cell to exhibit at least one characteristic of a TSC, thereby reprogramming the somatic cell to a cell exhibiting at least one characteristic of a TSC.
