The present invention further relates to CAR-NK cells obtained with the method and use of the CAR-NK cells in medicine, in particular for use in a method of treating cancer.

Abstract: A method of producing a collection of natural killer cells from CD34+ human stem cells. The invention further provides to a collection of natural killer cells thus produced and a pharmaceutical composition having such, natural killer cells. Further, the invention relates to a method of using the pharmaceutical composition as a medicament, in particular for immunotherapy in the treatment of malignancies.

Abstract: A method of manufacturing of Natural Killer (NK) Cells genetically modified with lentiviral vectors carrying a polynucleotide coding for a Chimeric Antigen Receptors (CARs). CAR-NK cells obtained with the method, and the use of the CAR-NK cells in medicine, in particular for use in a method of treating cancer is also disclosed.

Abstract: The present invention provides a cytokine-based culture method for ex vivo expansion of NK cells from postembryonic hematopoietic stem cells into a fully closed, large-scale, cell culture bioprocess. We optimized enrichment of CD34+ cells followed by efficient expansion in gas-permeable cell culture bags. Thereafter, expanded CD34+ cells could be reproducibly amplified and differentiated into CD56+CD3? NK cell products with a mean expansion of more than 2,000 fold and a purity of >90%. Also provided are collections of cultured cells having specific properties.

Abstract: In the fields of immunology and medicine, and more specifically in the fields of cancer treatment and immunotherapy, a composition for use in immunotherapy, in particular in a subject having a tumor is provided. The use of immunosuppressive pharmaceutical compositions is provided, in particular for use prior to immunotherapy. Methods for providing compositions for use in immunotherapy are also provided.

Abstract: The present invention relates to the ex vivo differentiation of NK cells from CD34+ hematopoietic stem cells. Such NK cells and their progenitor cells can be used in therapies of a broad range of malignancies. In the present invention it is shown that IL-12 modulates ex vivo NK cell differentiation. Specific, we achieved significantly higher expression of KIR, CD16 and CD62L in the presence of IL-12 in the cell culture system. The induction of receptor expression by IL-12 occurred predominantly on an augmented population of CD33+NKG2A+ NK cells early during NK cell differentiation. These cells further show enhanced cytolytic activity against MHC class I positive AML targets. In line with the enhanced CD16 expression, IL-12 modulated ex vivo generated NK cells exhibit an improved antibody-dependent-cytotoxicity, using anti CD20 antibody on various B cell targets. Additional to the enhanced expression of CD62L, we show that this cell population consists of a specific chemokine receptor profile.
