The disclosure provides methods for the long-term expansion of granulocyte-macrophage progenitors, the granulocyte-macrophage progenitors generated therefrom, and uses of the granulocyte-macrophage progenitors thereof.

The disclosure provides methods to genetically engineer granulocyte-macrophage progenitors (GMPs) to express a chimeric antigen receptor (CAR), and uses thereof, including for cancer immunotherapy.

Provided herein are compositions and methods for treating neurological disorders. In particular, provided herein are neutrophils that rescue damaged neurons, methods of making such neutrophils, and methods of promoting generation of such neutrophils in vivo.

The subject matter disclosed herein is generally directed to novel CD8.sup.+ tumor infiltrating lymphocyte (TIL) subtypes associated with response to immunotherapy treatment. Specifically, the subtypes are associated with checkpoint blockade therapy. Moreover, the subject matter disclosed herein is generally directed to methods and compositions for use of the subtypes. Also, disclosed herein are gene signatures and markers associated with the subtypes and use of said signatures and markers. Further disclosed are therapeutic methods of using said gene signatures and immune cell subtypes. Further disclosed are pharmaceutical compositions comprising populations of CD8.sup.+ TILs enriched for a specific subtype.

A method for keeping leukocytes alive ex vivo or in vitro, comprising maintaining the leukocytes in a medium comprising from 3 to 10 mM of glucose, in hypoxic conditions with P(02)10 mM Hg.

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

The present disclosure relates to a stage-specific process for manufacturing a population of neutrophils, such as chimeric antigen receptor-expressing (CAR-expressing) neutrophils (e.g., T cells and natural killer (NK) cells), from human pluripotent stem cells (hPSCs) using defined media and related compositions, kits, and methods of use (e.g., targeted cancer immunotherapy). Stage-specific processes for generating neutrophils and chimeric antigen receptor (CAR) neutrophils from human pluripotent stem cells (hPSCs) using chemically defined, feeder-free platforms and stage-specific morphogens; cell lines; pharmaceutical compositions; a method of treating cancer; and a kit are within the scopes of this disclosure.

The technology described herein is directed to compositions and cell culture media for increasing the lifespan of neutrophils. Also described are methods and kits for culturing neutrophils using the compositions or cell culture media. Such cultured neutrophils can be used to treat disorders such as neutropenia or microbial infections.

The invention relates to a granulocyte or stem cell (preferably granulocyte) for use in treating an infection. The invention also relates to said 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 an infection.

A blood product has three consecutive layers that are self-supporting. The first layer of the three consecutive layers has fibrin, the second layer has thrombocytes, and the third layer has leukocytes. The blood product is configured for application to a surgical site that is open so that the third layer is in direct contact with the surgical site.
