  • Publication number: 20130059339
    Abstract: A bioreactor (1) for the culture of cells (C) comprising a stack of carriers (7) for cell (C) adherence and liquid medium (M) distribution. The carriers (7) are stacked so as to define levels (6) between adjacent carriers (7) for the flow of the liquid medium (M). Adjacent levels (6) are fluidly interconnected via open spaces (2) so that the liquid medium (M) can flow from one level (6) to an adjacent level (6). The open spaces (2) between a first and an adjacent second level (6?) do not overlap with the one or more open spaces (2) between the second level (6?) and an adjacent third level (6?). One or more of the carriers may also include an area adapted to prevent cell adhesion or growth, thereby allowing for the viewing of cell growth on adjacent carriers from a vantage point external to the bioreactor. Related methods are also disclosed.

  • Patent number: 8389238
    Abstract: Efficient and prolonged hCFTR expression is one of the major obstacles for cystic fibrosis lung therapy. hCFTR mRNA expression levels depend on eukaryotic expression cassette components, prokaryotic backbone elements, and the gene transfer method may also influence transcriptional silencing mechanisms. A codon-optimized and CpG-reduced human CFTR gene (CO-CFTR) was made. Various vector modifications were tested to facilitate extended duration of CO-CFTR expression. Insertion of an extended 3?BGH transcribed sequence (712 bp) in an inverted orientation produced prolonged expression of CO-CFTR expression at biologically relevant levels. Further studies revealed that prolonged CO-CFTR expression is dependant on the orientation of the extended BGH 3? BGH transcribed sequence and its transcription, is not specific to the UbC promoter, and is less dependent on other vector backbone elements.

  • Patent number: 8372603
    Abstract: 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, hormones, 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.

  • Patent number: 8367319
    Abstract: Compositions and methods are provided to identify functional mutant ribosomes that may be used as drug targets. The compositions and methods allow isolation and analysis of mutations that would normally be lethal and allow direct selection of rRNA mutants with predetermined levels of ribosome function. The compositions and methods of the present invention may be used to identify antibiotics to treat a large number of human pathogens through the use of genetically engineered rRNA genes from a variety of species. The invention further provides novel plasmid constructs to be used in the methods of the invention.
