Abstract: Acute myeloid leukemia (AML) is a clonal disorder of hematopoietic stem and progenitor cells. It is a devastating disease with a poor prognosis and an average 5-year survival rate of about 30%. Disclosed herein are composition and methods for treating leukemia with a biomaterial comprising a polymer scaffold, a dendritic cell activating factor, a dendritic cell recruitment factor, and at least one leukemia antigen. The biomaterial-based vaccine disclosed herein promotes a potent, durable and transferable immune response against acute myeloid leukemia to prevent cell engraftment and synergizes with chemotherapy to prevent relapse.

Abstract: Described herein are signatures that characterize a particular stromal cell state, type, and/or subtype. In some embodiments, the signatures can characterize a dysfunctional stromal cell. In some embodiments, the signatures can be used to diagnose, treat, and/or prevent a disease. In some embodiments, the signatures can characterize remodeling in a bone marrow microenvironment. Also described herein are cell populations having a specific signature and modulated cells that can be modulate to have a specific signature.

Abstract: Disclosed herein are non-myeloablative antibody-toxin conjugates and compositions that target cell surface markers, such as the CD34, CD45 or CD117 receptors, and related methods of their use to effectively conditioning a subject's tissues (e.g., bone marrow tissue) prior to engraftment or transplant. The compositions and methods disclosed herein may be used to condition a subject's tissues in advance of, for example, hematopoietic stem cell transplant and advantageously such compositions and methods do not cause the toxicities that are commonly associated with traditional conditioning methods.

Abstract: The present disclosure describes a system, device and method for differentiating cells such as, for example, generating ex vivo common lymphoid progenitors (CLPs) from human hematopoietic stem cells (HSCs). The system and method can be fully automated requiring minimal touch input from a user. Once harvested, the CLPs can be transplanted into a patient for cellular immune therapy.

Abstract: 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.

Abstract: The present inventions relates to highly engraftable hematopoietic stem cell (heHSC) and related methods of production and use for the treatment of stem cell and progenitor cell disorders.

Abstract: Disclosed are compositions and related methods of recapitulating bone marrow stroma using scaffold materials (e.g., a porous alginate hydrogel scaffold) containing one or more cellular differentiation factors, and one or more growth factors. Such methods and compositions promote the formation of an ectopic nodule or site that can improve transplanted cell engraftment and selectively drive the development of lymphocytes and the reconstitution of the adaptive immunity after hematopoietic stem cell transplant.

Abstract: Disclosed herein novels methods and compositions that are useful for enhancing stem cell homing to, and engraftment in the target, tissues of a subject following stem cell transplant. In certain aspects, the inventions disclosed herein comprise a step of administering oncostatin M or a biologically active fragment, mutant, analog or fusion construct thereof to the subject and thereby increasing the stem cell homing and engraftment efficiency to the target tissues of the subject. Such methods and compositions may be used to improve subject survival and outcomes following, for example, hematopoietic stem cell transplant.

Abstract: Disclosed herein are methods for enhancing hematopoietic reconstitution of a subject. One method involves administering a therapeutically effective amount of an inhibitor of Embigin to a recipient subject and can also optionally include administering hematopoietic stem/progenitor cells to the subject. Another method involves administering an inhibitor of Embigin to a donor prior to harvest of hematopoietic stem/progenitor cells. Pharmaceutical compositions relating to the methods are also described.

Abstract: Disclosed herein are methods for enhancing hematopoietic reconstitution of a subject. One method involves administering a therapeutically effective amount of an inhibitor of IL-18 to a recipient subject and also administering hematopoietic stem/progenitor cells to the subject. Another method involves administering an inhibitor of IL-18 to a donor prior to harvest of hematopoietic stem/progenitor cells. Pharmaceutical compositions relating to the methods are also described.

Abstract: The disclosure relates to compositions, methods, and kits comprising glycyrrhetinic acid derivatives for selectively eradicating leukemic cells in a population or subject, and related methods of treating acute myeloid leukemia, and promoting survival of acute myeloid leukemia patients.
