Disclosed herein are methods for generating universal MHC/HLA-compatible hematopoietic progenitor cells and methods for generating custom patient-specific MHC/HLA-compatible hematopoietic progenitor cells. Compositions comprising the universal and custom hematopoietic progenitor cells and therapeutic applications thereof are also disclosed.

The present invention relates to myeloid-derived suppressor cells (MDSC) and exosomes derived therefrom (MDSC exo) and application thereof.

The present disclosure provides methods and compositions for microglia replacement therapy in a subject in need thereof. In some cases, the method involves administering myeloid cells to the central nervous system of a subject. In some cases, the myeloid cells are derived from embryonic or extraembryonic tissue. In some cases, the myeloid cells are genetically modified. The genetic modification may include a colony stimulating factor 1 receptor (CSF1R) variant that is resistant to a CSF1R inhibitor, yet retains sensitivity to its ligand (e.g., CSF1, IL34).

The present invention is directed to a method of generating multilineage potential cells by de-differentiation of somatic leukocytes in a mixed leukocyte suspension from a blood sample. The present invention is also directed to the use of the generated multilineage potential cells to treat conditions in humans and mammals.

This disclosure is directed to, inter alia, methods and systems for preparing oligopotent and unipotent progenitor cells of defined lineages in culture from an expanded source of CD34+ cells, media for making the same, and therapeutic compounds and compositions comprising the same for treatment a variety of diseases included, but not limited to, hematologic disorders, immune diseases, cancers, and infectious diseases.

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.

The invention relates to a method for determining the suitability of a granulocyte for treating cancer. The invention also relates to said granulocytes, methods for identifying said granulocytes and stem cells capable of differentiating into said granulocytes, compositions and kits comprising the same, as well as uses of the same for treating cancer.

Methods of tissue grafting, and more particularly methods for enhancing tissue graft revascularization, e.g., host engagement of pre-existing graft blood vessels.

The present invention is directed to indirect ultrasonic cavitation-derived perivascular cells, to methods of use of a perivascular cell composition, to a method of processing a tissue and to an apparatus for the processing of a tissue. The methods include the mechanic indirect ultrasonication of a cellular non-structural tissue, and produce a perivascular fraction which includes perivascular cells. The methods of use are directed to the treatment of a variety of diseases and disorders and to the improvement of a tissue in a subject. The apparatus is provided for the processing of cellular non-structural tissue.

The present invention relates to the in vitro production of erythrocytes/granulocytes and to the treatment of myelodysplastic syndrome using a method for inducing hemoblast differentiation. The present invention provides a media composition comprising gelsolin as an active ingredient for inducing the differentiation of hematopoietic precursor cells into erythrocytes/granulocytes, and a pharmaceutical composition comprising gelsolin as an active ingredient for treating myelodysplastic syndrome. Since the composition of the present invention improves the efficiency of differentiation of hematopoietic precursor cells into erythrocytes/granulocytes while maintaining a low rate of occurrence of cell dysplasia and having the effect of improving the enucleation rate and cell survivability, the present invention can be effectively used for producing erythrocytes/granulocytes in vitro and for treating myelodysplastic syndrome.
