    摘要: The invention relates to methods of isolating white blood cells (WBCs) from a sample, e.g., whole blood, using magnetic particles that specifically bind to WBCs and a series of specific steps and conditions. The methods can include one or more of decreasing the viscosity of the sample prior to WBC isolation, agitating the sample at specified frequencies, and/or using a sample container arranged such that all of the sample is placed in close proximity (e.g., within 5, 2, 1, or 0.5 mm) to the source of the magnetic field. The new methods provide for isolation of WBC preparations with high yield, purity, and viability. The methods are designed for compatibility with automation protocols for rapid processing of multiple samples.

    摘要: Methods and compositions are described for the treatment of type I insulin-dependent diabetes mellitus and other conditions using newly identified stem cells that are capable of differentiation into a variety of pancreatic islet cells, including insulin-producing beta cells, as well as hepatocytes. Nestin has been identified as a molecular marker for pancreatic stem cells, while cytokeratin-19 serves as a marker for a distinct class of islet ductal cells. Methods are described whereby nestin-positive stem cells can be isolated from pancreatic islets and cultured to obtain further stem cells or pseudo-islet like structures. Methods for ex vivo differentiation of the pancreatic stem cells are disclosed. Methods are described whereby pancreatic stem cells can be isolated, expanded, and transplanted into a patient in need thereof, either allogeneically, isogeneically or xenogenically, to provide replacement for lost or damaged insulin-secreting cells or other cells.

    摘要: Methods of treating autoimmune diseases, such as diabetes, characterized by faulty MHC class I antigen complex presentation are disclosed which involve exposure of the immune system of an individual susceptible to such disease to correctly associated MHC class I antigen complexes. Such treatment may involve obtaining cells from the individual, treating the cells to correct faulty MHC class I antigen presentation, then reinfusing the treated cells. Alternatively, syngeneic or haplotype-matched allogeneic lymphoid cells expressing normal levels of MHC class I antigen complexes may be used or intact MHC class I antigen complexes isolated from such lymphoid cells may be used in such treatment.

    摘要: Disclosed is a method for treating insulin resistance in a patient which involves isolating a skeletal muscle cell from an insulin-sensitive donor and transplanting the skeletal muscle cell into the skeletal muscle tissue of the insulin-resistant patient. The transplanted cell may be a muscle precursor cell, e.g., a myoblast or it may be derived from whole skeletal muscle tissue.
