20090075363 | CELL CULTURE CONTAINER AND METHOD OF PRODUCING THE SAME - To provide a cell culture chamber capable of reproducing a cell function in vivo, and a method of producing the same. The cell culture chamber according to the present invention has a concave-convex pattern formed on the surface on which cells are cultured. A concave portion of the concave-convex pattern includes cell culture portions and micro flow channels communicating with the cell culture portions. The bottom surface of each of the cell culture portions has a width 1.0 to 20 times an equivalent diameter of each of the cultured cells. A cell adhesion-inducing substance is formed only on the bottom surface and the side walls of the concave portion. | 03-19-2009 |
20090075366 | CELL CULTURE CHAMBER - It is intended to provide a cell culture chamber in a shape suitable for cell culture. It is also intended to provide a cell culture chamber which is inexpensive and facilitates observation. A cell culture chamber ( | 03-19-2009 |
20090149345 | MICROCHANNEL ARRAY AND METHOD FOR PRODUCING THE SAME, AND BLOOD MEASURING METHOD EMPLOYING IT - A microchannel array, a method of manufacturing the same, and a blood test method. The microchannel array is formed by joining first and second substrates, each including a fluid inlet and outlet on their surfaces. An internal space structure connects the fluid inlet and outlet, and includes an upstream flow channel connected with the fluid inlet, a downstream flow channel connected with the fluid outlet with a gap therebetween, and a micro flow channel connecting the upstream and downstream flow channels. A minimum distance from a center of a sectional surface of the micro flow channel to a side wall of the micro flow channel is smaller than that of the upstream and downstream flow channels. Each surface of the first and second substrates includes grooves for creating the upstream and downstream flow channels, and the surface of the second substrate has grooves for creating the micro flow channel. | 06-11-2009 |
20090170190 | CELL CULTURE CONTAINER AND METHOD OF PRODUCING THE SAME - An object of the present invention is to provide a cell culture chamber with which the survival rate of cells to be cultured can be increased, and a method of producing the same. A cell culture chamber according to the present invention includes a mass of projections formed of a plurality of microprojections 1 formed on a surface on which cells are cultured. The width or diameter of each of the microprojections 1 is in a range of 20 nm to 3 μm, and the aspect ratio of each of the microprojections is in a range of 0.2 to 3.0. Thus, there can be provided a cell culture chamber most suitable for the adhesion and differentiation/proliferation of cells to be cultured. | 07-02-2009 |
20100190253 | CELL CULTURE CONTAINER AND CELL CULTURE METHOD - To provide a cell culture chamber and a cell culture method that are capable of effectively constructing an intercellular network in a culture space. A cell culture chamber ( | 07-29-2010 |
20100331216 | CELL CULTURE METHOD - To provide a cell culture method capable of sustaining in-vivo functions for a long time by suppressing dedifferentiation. A cell culture method in accordance with the present invention is to culture cells in a multi-layered state in a minute partitioned space and to obtain a tissue structure having a function resembling an in-vivo function. When the cells are mammary gland epithelial cells, a hollow acinus-like structure can be formed. The minute partitioned space is particularly preferably a micro container in a cell culture container having a plurality of such micro containers on the surface. | 12-30-2010 |
20110045500 | CELL CULTURE METHOD AND SCREENING METHOD - Provided is a cell culture method whereby an in vivo function can be sustained over a long period of time and culture can be conducted using the minimum number of cells required. The cell culture method includes culturing undifferentiated cells in a layered state in a partitioned micro-space and obtains differentiated cells. When screening a pharmaceutical agent, undifferentiated cells capable of differentiating into liver cells, intestinal epithelial cells, nerve cells, myocardial cells and vascular endothelial cells are preferred. Particularly, in the prediction of pharmacokinetics or the like for humans, human cells are preferred. | 02-24-2011 |
20110207215 | CELL STORAGE METHOD AND CELL TRANSPORT METHOD - To provide a cell storage method to store living cells while maintaining the functions of the living cells. An aspect of the cell storage method is a method to store living cells ( | 08-25-2011 |
20110217725 | CELL CULTURE KIT, SCREENING METHOD, AND METHOD OF MANUFACTURING CELL CULTURE KIT - To provide a cell culture kit including cultured living cells of various donors, and a manufacturing method thereof. The cell culture kit includes a culture plate and living cells cultured thereon. The culture plate includes a plurality of microchambers ( | 09-08-2011 |
