The present invention provides a method for producing a γδT cell from an induced pluripotent stem cell, wherein the induced pluripotent stem cell is derived from a cell other than an αβT cell.

Provided herein are methods of generating a population of enucleated erythroid cells.

The present disclosure relates to the production of red blood cells from hematopoietic stem cells, by differentiating such cells in the presence of a protein that induces cell survival and proliferation.

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. By showing an increased capacity for adhesion to lymphendothelial cells and a specific chemokine receptor profile, we show that IL-12 provided the ex vivo generated NK cells with specific tissue-homing abilities.

The disclosure provided herein relates generally to mesenchymal-like stem cells hES-T-MiSC or T-MSC and the method of producing the stem cells. The method comprises culturing embryonic stem cells under conditions that the embryonic stem cells develop through an intermediate differentiation of trophoblasts, and culturing the differentiated trophoblasts to hES-T-MSC or T-MSC, T-MSC derived cell and cell lineages T-MSC-DL are also described. Disclosed also herein are solutions and pharmaceutical compositions comprising the T-MSC and/or T-MSC-DL, methods of making the T-MSC and T-MSC-DL, and methods of using the T-MSC and T-MSC-DL for treatment and prevention of diseases, specifically, T-MSC and T-MSC-DL are used as immunosuppressive agents to treat multiple sclerosis and autoimmune diseases.

The disclosure relates to compositions comprising hematopoietic cells and methods of using the same. The disclosure also relates to methods of reprogramming endothelial cells into hematopoietic cells by exposing the endothelial cells to at least one hematopoietic effector.

Provided herein are methods for the efficient in vitro differentiation of somatic cell-derived pluripotent stem cells to hematopoietic precursor cells, and the further differentiation of the hematopoietic precursor cells into immune cells of various myeloid or lymphoid lineages, particularly T cells, NK cells, and dendritic cells. The pluripotent cells may be maintained and differentiated under defined conditions; thus, the use of mouse feeder cells or serum is not required in certain embodiments for the differentiation of the hematopoietic precursor cells.

Provided herein are methods for the efficient in vitro maintenance, expansion, culture, and/or differentiation of pluripotent cells with disruption of the MeCP2 gene into various erythroid, myeloid, lymphoid, or endoderm lineages, particularly mature erythrocytes. The pluripotent cells may be maintained and differentiated under defined conditions; thus, the use of mouse feeder cells or serum is not required in certain embodiments for the differentiation of the precursor cells.

The present invention provides: a platelet production promoter that contains one or more substances selected from the group consisting of Wnt inhibitors and FMS-like tyrosine kinase (FLT) inhibitors; and a platelet production method that uses this platelet production promoter.

Methods for producing megakaryocytic progenitors (preMKs) and megakaryocytes (MKs) from stem cells are provided. The present disclosure further provides compositions comprising preMKs and MKs and their lysates, and also methods of use of preMKs, MKs, their lysates and compositions thereof.
