Human/human hybrid cells were made via fusion of human embryonic kidney cells (293S) and modified Burkitt's lymphoma cells (2B8). The fusion cells are useful as host cells for the recombinant expression of mammalian genes. The advantages of using these hybrid clones of human kidney- and B-cells, called HKBs, for mammalian gene expression, include (i) the cells are negative for immunoglobulin expression, (ii) the cells grow easily in plasma protein-free medium (with or without the addition of recombinant insulin) as suspension cultures in a shake flask or in a fermenter (iii) the cells are very susceptible for transfection of DNA, and (iv) the cells secrete high levels of heterologous recombinant proteins, such as recombinant monoclonal antibodies, soluble ICAM-1, rIL-4, and rFVIII.

The present invention relates to a transplant rejection in an animal suppressed by administration of an antibody directed at a cell surface antigen selected from the group consisting of CD4, CD8, CD154, LFA-1, CD80, CD86 and ICAM-1, preferably an anti-CD4 antibody, together with a non-cellular protein antigen to generate in the animal a population of regulatory T-lymphocytes; reactivating said population of regulatory T-lymphocytes by further administration to the animal of the non-cellular protein antigen; and transplanting said organ or tissue whilst said population of regulatory T-lymphocytes is activated. Regulatory T cells can be generated ex vivo by culturing T cells with an antibody directed at a cell surface antigen selected from the group consisting of CD4, CD8, CD154, LFA-1, CD80, CD86 and ICAM-1, in the presence of cells that present either alloantigen or a non-cellular protein antigen. Ex vivo generated T-lymphocytes can be used as an alternative method of overcoming transplant rejection or in combination with the in vivo method. A similar approach can be adopted for the treatment of autoimmune conditions.

A method of obtaining a mixture of cells enriched in hepatic progenitors is developed which comprises methods yielding suspensions of a mixture of cell types, and selecting those cells that are classical MHC class I antigen(s) negative and ICAM-1 antigen positive. The weak or dull expression of nonclassical MHC class I antigen(s) can be used for further enrichment of hepatic progenitors. Furthermore, the progenitors can be selected to have a level of side scatter, a measure of granularity or cytoplasmic droplets, that is higher than that in non-parenchymal cells, such as hemopoietic cells, and lower than that in mature parenchymal cells, such as hepatocytes. Furthermore, the progeny of the isolated progenitors can express alpha-fetoprotein and/or albumin and/or CK19. The hepatic progenitors, so isolated, can grow clonally, that is an entire population of progeny can be derived from one cell. The clones of progenitors have a growth pattern in culture of piled-up aggregates or clusters. These methods of isolating the hepatic progenitors are applicable to any vertebrates including human. The hepatic progenitor cell population is expected to be useful for cell therapies, for bioartificial livers, for gene therapies, for vaccine development, and for myriad toxicological, pharmacological, and pharmaceutical programs and investigations.
