  • Publication number: 20230363377
    Abstract: A transport container is configured to capture air bubbles remaining in a container with a simple mechanism and a simple operation to protect a graft. The transport container includes: a lid that seals a container for housing a graft, in which the lid has a protrusion protruding toward a space inside the container in a state of being attached to the container. A substantially annular groove is formed on a lower surface of the protrusion. Gas and liquid inside the container housing the graft and liquid are pushed out by the lid to achieve a liquid-tight state, and air bubbles in the liquid can be captured in the groove on the lower surface.

  • Patent number: 11398032
    Abstract: [Problem] To evaluate objective cell groups by estimating a mixing ratio of objective cell group without affecting treatment itself and its production process when the objective cell groups include plural kinds of cell groups having different attributes, and to provide an image analysis system and a culture management system capable of accurately perform a quality control and a production control with low cost. [Solution] The cell quality evaluation system 1 detects a feature amount in each cell easily analyzable from images, and estimates a mixing ratio of each of plural kinds of cell groups included in the objective cell groups based on a distribution of the detected feature amount and pre-recorded information of the feature amount. As the feature amount, the embodiment uses a migration speed of each cell, easily distinguishable by analyzing tracking of each cell from plural images in time series.

  • Publication number: 20220049222
    Abstract: A three-layer structure is comprised of an extra-cellular matrix, a sheet-shaped cell culture, and a biodegradable gel layer (single layer). By virtue of this three-layer structure, breakage of the sheet-shaped cell culture due to high spray pressure is reduced. The fibrin gel may be formed on one surface of the sheet-shaped cell culture by spraying of a thrombin liquid. A production method may involve culturing cells on a temperature-responsive cell culture substrate, dripping fibrinogen onto a sheet-shaped cell culture having an extra-cellular matrix on a lower surface thereof, further spraying a thrombin liquid onto the sheet-shaped cell culture from an oblique direction, whereby the result is a three-layer structure having a fibrin gel layer only on one surface of the sheet-shaped cell culture and having an extra-cellular matrix layer on the opposite surface.
