The present invention relates to the use of tissue non-specific alkaline phosphatase (TNAP) as a marker for identifying and/or isolating adult multipotential cells. The present invention also relates to cell populations enriched by methods of the present invention and therapeutic uses of these cells.

The present invention is directed generally to eukaryotic cells comprising single-celled organisms that are introduced into the eukaryotic cell through human intervention and which transfer to daughter cells of the eukaryotic cell, and methods of introducing such single-celled organisms into eukaryotic cells. The invention provides single-celled organisms that introduce a phenotype to eukaryotic cells that is maintained in daughter cells. The invention additionally provides eukaryotic cells containing magnetic bacteria. The invention further provides eukaryotic cells engineered with single-celled organisms to allow for multimodal observation of the eukaryotic cells. Each imaging method (or modality) allows the visualization of different aspects of anatomy and physiology, and combining these allows the imager to learn more about the subject being imaged.

It is an object of the present invention to provide an antibody binding to CDH6 and having internalization activity, an antibody-drug conjugate of the antibody and a drug having antitumor activity, a pharmaceutical product comprising the antibody-drug conjugate and having therapeutic effects on a tumor, a method for treating a tumor using the antibody, the antibody-drug conjugate or the pharmaceutical product, and the like. The present invention provides an anti-CDH6 antibody having internalization activity, an antibody-drug conjugate of the antibody and a drug having antitumor activity, a pharmaceutical product comprising the antibody or the antibody-drug conjugate, and a method for treating a tumor.

The present invention provides compositions, systems, kits, and methods for combining a. single myeloma cell and a single B-cell (e.g., from an animal exposed to a desired antigen) via discrete entity (e.g., droplet) microfluidics. In certain embodiments, a microfluidic device is used to merge a discrete entity containing a B-cell, and a discrete entity containing a myeloma cell, and a discrete entity containing gellable material, at a merger region via a trapping element in order to generate a combined discrete entity. In further embodiments, the combined discrete entity is treated such that a gelled discrete entity is formed.

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.

In order to improve the efficiency of gene introduction in CAR therapy employing a transposon method, provided is a method for preparing genetically-modified T cells expressing chimeric antigen receptor, comprising: (1) a step of preparing non-proliferative cells which are obtained by stimulating a group of cells comprising T cells using an anti-CD3 antibody and an anti-CD28 antibody followed by a treatment for causing the cells to lose their proliferation capability; (2) a step of obtaining genetically-modified T cells into which a target antigen-specific chimeric antigen receptor gene has been introduced using a transposon method; (3) a step of mixing the non-proliferative cells prepared by step (1) with the genetically-modified T cells obtained by step (2), and co-culturing the mixed cells while stimulating the mixed cells using an anti-CD3 antibody and anti-CD28 antibody; and (4) a step of collecting the cells after culture.

An antibody that binds a glycosylated protein is disclosed, wherein the glycosylation comprises the glycan motif Fucα1-2Galβ1-3GlcNAcβ1-3Galβ1 or Fucα1-2Galβ1-3GlcNAc. Antibodies that are cytotoxic against undifferentiated pluripotent cells are also disclosed.

The purpose of the present invention is to provide a method for detecting, in a selective and simple manner, an oxidized form of HD5 which is human α-defensin, that is, HD5 having intramolecular disulfide bonds that function beneficially in the human body.

[Solution] The present invention relates to: two kinds of novel monoclonal antibodies that contain amino acid sequences of SEQ ID NO: 1-6 or 7-12 as a CDR and that specifically bind to human α-defensin HD5 having intramolecular disulfide bonds; an immunological detection method using the antibodies; and a kit containing the antibodies.

Provided is a method for preparing genetically-modified T cells expressing chimeric antigen receptor, comprising: (i) a step of preparing non-proliferative cells holding a viral peptide antigen, which are obtained by stimulating a group of cells comprising T cells using an anti-CD3 antibody and an anti-CD28 antibody followed by culturing in the presence of the viral peptide antigen and a treatment for causing the cells to lose their proliferation capability; (ii) a step of obtaining genetically-modified T cells into which a target antigen-specific chimeric antigen receptor gene has been introduced using a transposon method; (iii) a step of mixing the non-proliferative cells prepared by step (i) with the genetically-modified T cells obtained by step (ii), and co-culturing the mixed cells; and (iv) a step of collecting the cells after culture.

The present invention relates to a claudin 18.2 (CLDN18.2) antibody and the use thereof in treating cancers, such as gastric cancer, pancreatic cancer, and esophageal cancer.
