Isolated cells are described that are not embryonic stem cells, not embryonic germ cells, and not germ cells. The cells can differentiate into at least one cell type of each of at least two of the endodermal, ectodermal, and mesodermal lineages. The cells do not provoke a harmful immune response. The cells can modulate immune responses. As an example, the cells can suppress an immune response in a host engendered by allogeneic cells, tissues, and organs. Methods are described for using the cells, by themselves or adjunctively, to treat subjects. For instance, the cells can be used adjunctively for immunosuppression in transplant therapy. Methods for obtaining the cells and compositions for using them also are described.

Immunomodulatory properties of multipotent adult progenitor cells and uses thereof

Immunomodulatory properties of MAPCs and uses thereof

Isolated monoclonal antibodies are disclosed herein that specifically bind a cell surface antigen expressed on the human pancreatic endocrine cells or a subset thereof, and/or a precursor thereof. Isolated monoclonal antibodies are also disclosed herein that specifically bind a cell surface antigen expressed on human pancreatic exocrine cells or human ductal cells. Humanized forms of these antibodies, and functional fragments of these antibodies, are also disclosed. The antibodies can be conjugated to an effector molecule, or a detectable marker. These antibodies are of use to detect and/or isolate pancreatic cells or a subset thereof. Methods of treating a pancreatic tumor are also disclosed.

Monoclonal antibodies and their use

Isolated monoclonal antibodies are disclosed herein that specifically bind a cell surface antigen expressed on the human pancreatic endocrine cells or a subset thereof, and/or a precursor thereof. Isolated monoclonal antibodies are also disclosed herein that specifically bind a cell surface antigen expressed on human pancreatic exocrine cells or human ductal cells. Humanized forms of these antibodies, and functional fragments of these antibodies, are also disclosed. The antibodies can be conjugated to an effector molecule, such as a detectable marker, a therapeutic agent, or a toxin. These antibodies are of use to detect and isolate pancreatic cells or a subset thereof. The antibodies can be used for in vitro or in vivo detection and/or isolation of pancreatic endocrine cells. Methods of treating a pancreatic tumor are also disclosed. In several examples, the isolated monoclonal antibodies bind pancreatic endocrine cells and can be used to detect diabetes or a pancreatic endocrine cell tumor.
