The invention discloses a bioreactor with a vessel defining an inner volume, agitation means and at least one addition tube, wherein a delivery orifice in the addition tube is located within the inner volume and a check valve is arranged in proximity of the delivery orifice for allowing flow of a fluid in the direction from the addition tube into the inner volume of the vessel and blocking flow in the reverse direction.

The present disclosure relates to a method of obtaining a cell where fucosylation pathways are modified, leading to production of partially fucosylated and non-fucosylated protein products, specifically antibodies from the cell. The present disclosure employs the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technology. The method of the present disclosure targets the Fut8 gene and GMD gene in a cell. Such products are used in developing therapeutics and biomarkers, and in diagnosis and prognosis of diseases.

An access system having a communication component that interfaces with a first device and a second device, where the first device is located inside or on an entity and coupled to a biological organism of the entity, and where the second device is located outside the entity and a controller component that controls a function of the first device, employing the communication component, to provide treatment to the biological organism of the entity coupled to the first device based on a request received from the second device.

The present disclosure provides methods for inducing cell cycle reentry of postmitotic cell. The present disclosure further provides cells and compositions for treating diseases, such as cardiovascular diseases, neural disorders, hearing loss, and diabetes.

The present invention relates to a method of enabling pooled-library based nucleic acid constructs screening in insect cells.

A cell culture device (1) includes: a culture vessel (10 ) that accommodates a cell suspension containing cells and a culture medium; and a stirring device (30) that is provided at a bottom part of the culture vessel (10) to stir the cell suspension accommodated in the culture vessel (10). The stirring device (30) has a shaft part (32), and a rotating part (33) rotatable with the shaft part (32) as a rotation axis. The rotating part (33) has a hole part (36) into which the shaft part (32) is inserted, and a gap (37) of 100 μm or more is secured between an interior wall demarcating the hole part (36) and the shaft part (32). A closing part (38) that closes an end part of the gap (37) in an axial direction of the rotation axis is provided.

In one aspect, the present invention jointly expresses SOD and NAMPT proteins. The activity of SOD and NAMPT expressed by silkworm pupae inoculated with viruses is higher than that of silkworm pupae that are not inoculated with viruses, which proves that it is feasible to jointly express SOD and NAMPT with silkworms. It is expected to prepare an effective anti-aging drug.

The present invention relates to a multicellular construct that includes cells and a scaffold. The scaffold is constituted by a layered composite that comprises a gelatin nonwoven containing gelatin as a main component, and a gelatin film containing gelatin as a main component and layered on one surface of the gelatin nonwoven, and the cells are present in at least one of a region on the surface of the gelatin nonwoven and a region inside the nonwoven. The multicellular construct can be produced by arranging the scaffold in a swollen state inside the culture vessel whose inner surface is in the dry state such that the gelatin film of the scaffold is in contact with the inner bottom surface of the culture vessel, dripping a cell suspension onto the gelatin nonwoven of the scaffold, and then culturing the cells. This makes it possible to provide a multicellular construct with high seeding efficiency in which desorption of cells from a scaffold is suppressed, a method for manufacturing the same, a kit for producing the same, and a method for evaluating a compound using the same.

The invention provides methods of preparing a sample of viable diseased cells obtained from a human subject for clinical testing, wherein the methods inhibit anoikis and/or anoikis in the cells while maintaining the physiological functions and genomic composition of the cells when they were in vivo. In the methods of the invention, primary cells are cultured in media comprising at least one anoikis inhibitor, preferably at least one inhibitor of an intrinsic anoikis pathway and at least one inhibitor of an extrinsic anoikis pathway, under anti-anoikis atmospheric conditions, such as greater than 2% and less than 20% oxygen. Method combining multiple culturing conditions, including surface attachment under conditions that inhibit anoikis, are also provided. Compositions and kits for use in the methods of the invention are also provided.

Disclosed are an immunochemical assay device and a method of using the immunochemical assay device for detecting one or more targets or markers such as Cardiac Troponin I, NT-pro-BNP, D-dimer and/or cross-linked fibrin in a fluid sample.
