Methods and composition for production of T cells are provided. Also provided are therapeutic methods using engineered T cells. For example, in certain aspects methods include preparing three dimensional cell culture compositions comprising stroma cells and hematopoietic stem or progenitor cells in a serum-free medium for producing T cells.

The present invention relates to an isolated cellular targeted delivery system comprising a CD45+ leukocyte cell comprising within said cell a complex of one or more iron binding proteins and/or a label as well as methods for producing such isolated cellular targeted delivery system and uses of such system for therapy diagnosis and in particular for diagnosis of cancer, particularly metastatic cancer, in particular for therapy of cancer.

Provided are methods and compositions for obtaining genome-engineered iPSCs, and derivative cells with stable and functional genome editing at selected sites. Also provided are cell populations or clonal cell lines derived from genome-engineered iPSCs, which comprise targeted integration of one or more exogenous polynucleotides, and/or in/dels in one or more selected endogenous genes.

Disclosed are methods for methods for quantitating and standardizing an anti-inflammatory response of a product and methods for determining the likelihood that a product would produce an anti-inflammatory effect in a subject when administered to the subject. Accordingly, disclosed herein are methods, compositions and kits for characterizing and evaluating the anti-inflammatory effect of products, particularly therapeutic biological products.

This disclosure relates to growth media and environments for in vitro culturing of cells that produce or are capable of producing antibodies. In certain embodiments, the media comprises IL-6, fibronectin, and typically a saccharide. In certain embodiments, the disclosure contemplates cell culture compositions comprising IL-6 and fibronectin that are derived from proteins secreted from mesenchymal stromal/stem cells (MSCs). In certain embodiments, the disclosure contemplates enclosures comprising culture compositions disclosed herein that are in ambient air or optionally in an environment wherein oxygen is absent or at a low concentration.

To enable stable supply of differentiated T cells, the present invention provides a method for producing, or a method for expansion culture, or a kit for expansion culture of a CD3-positive cell in which T cell marker CD3 is expressed on the cell membrane.

This invention relates to exosome compositions and methods of using them.

The disclosure provides in some aspect methods and compositions related to culturing and engineering T cells that maintain less differentiated state. The T cells are cultured in conditions that induce Notch signaling The resulting T cells exhibit maintenance of a less differentiated state for prolonged periods and have reduced susceptibility to exhaustion. Also provided are the cells produced by the methods, as well as related compositions and methods of use for adoptive therapy.

The present disclosure relates, at least in part, to mycobacterial polynucleotides and polypeptides, to fragments or variants thereof, to cells comprising the mycobacterial polynucleotides and polypeptides, to cells comprising the mycobacterial polynucleotides and polypeptides, that are engineered to expand T-cells ex vivo, and to methods of use thereof.

Provided herein are stimulated placental stem cells and methods of treating individuals having diseases or disorders of the circulatory system using stimulated placental cells. The invention also provides methods of inducing angiogenesis using such stimulated cells or populations of cells comprising such stimulated cells.
