Patent number: 9951305Abstract: The present invention provides a carrier device including a culture vessel and a flow channel, which have a closed structure, for supplying cell liquid or a culture medium into the flow channel; and a method of aseptically injecting liquid, such as the cell or the culture medium, into the culture vessel and the flow channel. The present invention provides a carrier jig 19 including a drive base 27, a culture vessel base 21 that holds a culture vessel 20, a culture medium base 32 that holds a cell bag 60 and the like for the culture medium and the cell, and a detachable flow channel 40, those of which are held by a lift 98 to be carried to a cell culture device. A part of the flow channel 40 and the cell bag 60 mounted on the carrier jig 19 are put into a clean space 78. The cell and the culture medium are supplied into the flow channel 40 by using the cell bag 60 and other bags in the clean space, and then, an injection port 89 is closed.Type: GrantFiled: April 4, 2012Date of Patent: April 24, 2018Assignee: Hitachi, Ltd.Inventors: Toyoshige Kobayashi, Ryota Nakajima, Takayuki Nozaki, Shizu Matsuoka

Patent number: 9951307Abstract: A method for growing organically derived building materials in the form of a moldable substrate that can be engineered to serve a wide range of manufacturing and construction applications is presented. In particular, the embodiments consider a plurality of fungal molded shapes preferably grown from fungal inoculum and mechanically compressed at least once during the growing process as well as integration of structure support members to the fungal structure. The present invention provides a fungal substrate which could be molded, and easily and cheaply preprocessed to precise geometric specifications. The organically derived building materials also incorporate layers of structural reinforcements to improve load bearing and other structural capacities.Type: GrantFiled: August 7, 2016Date of Patent: April 24, 2018Assignee: Mycoworks, Inc.Inventor: Philip Ross

Patent number: 9951308Abstract: Provided is a cell culture substrate, in which polymer (B) having a lower critical solution temperature contained in the substrate is a copolymer of a monomer (a) that becomes a hydrophobic polymer in homopolymerization and a monomer (b, c or d) that becomes a hydrophilic polymer in homopolymerization, which is uncrosslinked, and the lower critical solution temperature of the obtained copolymer (B) can be controlled widely by the types and ratio of the two monomers, to easily detach the cultured cells from the culture substrate surface rapidly without using protein hydrolase and collect the cells without damage. This cell culture substrate contains a polymer (A) of a (meth)acrylic acid ester monomer (a), one or more types of inorganic materials (C) selected from a water-swellable clay mineral and silica, and a polymer (B) having a lower critical solution temperature and including a monomer (a) and a monomer (b, c or d).Type: GrantFiled: December 11, 2014Date of Patent: April 24, 2018Assignee: DIC CorporationInventor: Tetsuo Takada

Patent number: 9951310Abstract: Methods for preparing ex vivo T cell cultures using IL-21 compositions for use in adoptive immunotherapy are described. Addition of IL-21 to cultures of non-terminally differentiated T cells population, either isolated or present in peripheral blood mononuclear cells are exposed to one or more tumor antigens, and in the presence of IL-21 compositions and antigen presenting cells (APCs), the resulting T cell population has an enhanced antigen-specificity, and can be reintroduced into the patient. Methods are also disclosed for identifying tumor antigens by culturing T cell populations exposed to IL-21 compositions and APCs in the presence of tumor material.Type: GrantFiled: August 25, 2014Date of Patent: April 24, 2018Assignee: FRED HUTCHINSON CANCER RESEARCH CENTERInventor: Cassian Yee
