Provided herein are methods, compositions, and kits for expanding natural killer cells in the absence of feeder cells.

Compositions and methods for preparing T cell compositions and uses thereof are described, including methods for treating cancer in a subject in need thereof by administering T cells induced with peptides comprising at least one of KRAS epitope having a sequence GACGVGKSA that binds to a protein encoded by an HLA allele C03:04; or having a sequence GAVGVGKSA that binds to a protein encoded by an HLA allele C03:03 wherein the respective protein encoded by the HLA allele is expressed in a cell of the subject. Also included are immunogenic compositions comprising peptide(s) comprising an epitope described above, or antigen presenting cells loaded with the peptide(s) comprising the epitope.

Mesenchymal stem cells which express TNF-α receptor Type I in an amount of at least 13 pg/10.sup.6 cells. Such mesenchymal stem cells inhibit the proliferation of lymphocytes and may be employed, in particular, in the treatment of graft-versus-host disease.

The invention relates to an in vitro method to generate T cell progenitors, comprising the step of culturing CD34+ cells in a medium containing TNF-alpha and/or an antagonist of the Aryl hydrocarbon/Dioxin receptor, in particular StemRegenin 1 (SR1), in presence of a Notch ligand and optionally a fibronectin fragment.

The present invention relates to an in vitro culture of haematopoietic cells, wherein said haematopoietic cells differentiate to form granulocytes characterised by the ability to kill cancer cells. The invention also relates to said granulocytes, methods for identifying said haematopoietic cells and granulocytes, compositions and kits comprising the same, as well as uses of the same for treating cancer.

Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.

Methods of expanding tumor infiltrating lymphocytes (TILs) using a tumor necrosis factor receptor superfamily (TNFRSF) agonist, such as a 4-1BB agonist, a CD27 agonist, a glucocorticoid-induced TNF receptor-related agonist, an OX40 agonist, a HVEM agonist, or a CD95 agonist, and uses of such expanded TILs in the treatment of diseases such as cancer are disclosed herein. In addition, in some embodiments, therapeutic combinations of TILs and TNFRSF agonists useful in the treatment of diseases such as cancer, including compositions, uses, and dosing regimens thereof, are disclosed herein.

The present invention relates to a method of treating a tumor disease, comprising one or more administrations of a T cell product, a T cell product for use in a method of treating a tumor disease, as well as a kit for use in a method of treating a tumor disease.

Disclosed herein are methods and compositions comprising placental adherent stromal cells for treating viral infections and sequelae thereof.
