  • Publication number: 20200165653
    Abstract: A method of measuring a fluid secretion function of epithelial cells includes: seeding organoids established from epithelial cells in a culture receptacle and culturing the organoids in a gel in each well of the culture receptacle for a prescribed period of time; capturing a multi-pixel image of each organoid-containing well; detecting as organoids regions in the captured image that are regions surrounded by edges having at least a prescribed difference in pixel intensity value with respect to that of a background; calculating an area inside the edges for the object; selecting whether or not the object is an organoid-derived object; and determining whether or not an object selected as being derived from the organoid is subject to analysis. No cell staining product for staining the organoids is added when performing the imaging process.

  • Patent number: RE44821
    Abstract: A color filter having two-layered light-shielding sections without a black matrix is provided, which reduces the level difference from the colored materials for pixels with a simple method and makes it possible to remove the color layer on the said sections. A red color layer having stripe-shaped red pixel formation sections and a blue color layer having stripe-shaped blue pixel formation sections are overlapped to form two-layered light-shielding sections. A green color layer having island-shaped green pixel formation sections is overlapped with the red and blue color layers, placing the green pixel formation sections in the overlapped green pixel windows of the red and blue color layers. Only the peripheries of the green pixel formation sections are placed on the light-shielding sections to facilitate the removal of the peripheries by polishing.
