  • Patent number: 10940180
    Abstract: The invention relates to the fields of biochemistry, pharmacy and oncology. The invention particularly relates to the use of novel stem cell markers for the isolation of stem cells. The invention further relates to the obtained stem cells and their use in for example research or treatment, for example, for the preparation of a medicament for the treatment of damaged or diseased tissue. In one of the embodiments, the invention provides a method for obtaining (or isolating) stem cells comprising optionally preparing a cell suspension from a tissue or organ sample, contacting said cell suspension with an Lgr 6 or 5 binding compound, identify the cells bound to said binding compound, and optionally isolating the stem cells from said binding compound. The invention further relates to means suitable for cancer treatment and even more specific for the treatment of cancer by eradicating cancer stem cells.

  • Publication number: 20180282799
    Abstract: The current invention relates to strategies for selection and amplification of genomic regions of interest. The strategy involves an amplification step in a host cell. A target nucleotide sequence associated with the genomic region of interest is used to selectively provide a DNA circles derived from the genomic region of interest with an origin of replication and a selection gene. This is in particular useful i.a. for determining DNA sequences of a genomic region of interest, for use in building contiguous sequences and/or for DNA mapping.
