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.

Abstract: Disclosed herein is a tool, a kit, and associated method for transferring a membranous tissue composed of cells derived from a living body. The tool can include a first sheet-like supporting member disposed on one side of the membranous tissue in a wet state, and a second sheet-like supporting member disposed on the other side of the membranous tissue in a wet state. The first supporting member and the second supporting member can be configured to entirely hold the membranous tissue, such that a frictional force between the first supporting member and the membranous tissue is larger than a frictional force between the second supporting member and the membranous tissue.

Abstract: A stent includes a stent body in which struts are joined mutually while intersecting and which is formed tubularly as a whole, and a drug coat layer on the outer surface of the struts. The strut has a bend which is deformed as the stent body expands/contracts in the radial direction, and the drug coat layer with which the bend is coated is formed in such a manner that the drug coat layer is mountain-shaped in a cross-section perpendicular to the axis of the strut and the ridgeline of the mountain shape extends in a wavy shape along the longitudinal direction of the strut. The drug coat layer deforms relatively easily without using plasticizer as the stent deforms and is not so susceptible to causing problems such as peeling, destruction, damage or falling off of the drug coat later.
