    摘要: Disclosed are compositions and methods for increasing the longevity of a cell culture and permitting the increased production of proteins, preferably recombinant proteins, such as antibodies, peptides, enzymes, growth factors, interleukins, interferons, hamiones, and vaccines. Cells transfected with an apoptosis-inhibiting gene or vector, such as a triple mutant Bcl-2 gene, can survive longer in culture, resulting in extension of the state and yield of protein biosynthesis. Such transfected cells exhibit maximal cell densities that equal or exceed the maximal density achieved by the parent cell lines. Transfected cells can also be pre-adapted for growth in serum-free medium, greatly decreasing the time required to obtain protein production in serum-free medium. In certain methods, the pre-adapted cells can be used for protein production following transformation under serum-free conditions. The method preferably involves eukaryotic cells, more preferably mammalian cells.

    摘要: The present invention discloses a method of generation of antigen presenting cells, comprising: a. collecting said cells from a subject, b. activating said collected cells; c. culturing and optionally expanding ex vivo said activated cells; d. treating said cultured and optionally expanded cells with DNA hypomethylating agents so that said cells concomitantly express multiple tumor associated antigens. The cells obtainable according to the method of the present invention, as well as the cellular components thereof whether alone or in combination with said cells, are useful for prevention and treatment of malignancies of different histotype that constitutively express one or more of the multiple tumor associated antigens that are expressed in said cells. Conveniently, said cells and/or cellular components are in the form of a vaccine. Said vaccines are advantageous over the prior art in that as they concomitantly express multiple/all methylation-regulated tumor associated antigens.
