Methods and compositions are provided for combined transplantation of a solid organ and hematopoietic cells to a recipient, where tolerance to the graft is established through development of a persistent mixed chimerism. An individual with persistent mixed chimerism, usually for a period of at least six months, is able to withdraw from the use of immunosuppressive drugs after a period of time sufficient to establish tolerance.

The present disclosure provides immunogenic compositions comprising the N-domain of carcinoembryonic antigen (CEA). These compositions are useful for inducing or enhancing an immune response, for inhibiting tumor cell growth and for treating cancer.

Methods of inhibiting metastasis in cancer patients are provided, wherein the methods comprise reducing TGF signaling, for example, by reducing TGF receptor II expression in myeloid cells. Vectors comprising a TGF receptor II RNAi nucleic acid sequence operably linked to a myeloid specific promoter also are provided. A method of diagnosing cancer in an individual by determining TGF receptor II expression in myeloid cells in the individual is provided. Additionally, a method of modulating TGF activity in myeloid cells in a cancer patient comprising administering a regulator of at least one of the GSK3 and PI3K pathways to the patient is provided.

The present invention features compositions and methods related to the isolation, culture and therapeutic use of CD31-expressing cells.

The present disclosure generally regards methods and compositions for providing multi-lineage hematopoietic precursor cells from pluripotent stem cells (PSCs). The PSCs comprise an expression construct encoding an ETS/ERG gene, GATA2 and HOXA9. Also provided are methods for providing hematopoietic stem cells capable of long-term engraftment in mammals, such as humans. Further provided are therapeutic compositions including the provided hematopoietic stem cells and precursors of hematopoietic cells, and methods of using such for the treatment of subjects.

Methods and compositions are provided for combined transplantation of a solid organ and hematopoietic cells to an HLA mismatched recipient, where tolerance to the graft is established through development of a persistent mixed chimerism. An individual with persistent mixed chimerism, usually for a period of at least six months, is able to withdraw from the use of immunosuppressive drugs after a period of time sufficient to establish tolerance.

The invention features therapies using an IL-15-based superagonist complex to effectively treat subjects with cancer.

Disclosed herein are methods and compositions dock and lock (DNL) complexes comprising an AD moiety selected from an AKAP protein and a DDD moiety selected from a protein kinase A regulatory subunit. Also disclosed are fusion proteins comprising an AD moiety or DDD moiety attached to an effector moiety. The DDD moieties form dimers that bind to the AD moiety to form the DNL complexes. The effector moieties may be selected from a wide range of known effector moieties that produce one or more physiological effects, including but not limited to cell death. The DNL complexes may further comprise one or more diagnostic and/or therapeutic agents. The DNL complexes are of use for treating and/or diagnosing a variety of diseases or conditions.

Methods and compositions for treating or ameliorating lower back pain by administering an effective amount of one or more cell types, alone, and/or in combination with a matrix, and/or in combination with growth factors, in order to stimulate lumbar angiogenesis, decrease inflammation, and stimulating regeneration.

The present invention relates to a method of detecting a therapeutic cell expressing a dopamine transporter (DAT) at a central nervous system (CNS) site in a subject, which comprises the administration of a DAT tracer to the subject, wherein the presence of a therapeutic cell which expresses the DAT is determined.
