  • Patent number: 9968639
    Abstract: Fresh human pancreas tissue can be used as a source of cells when to identify and select a non-stem cell population that is predisposed to be a source for surrogate pancreatic cells that can be used in treating insulin-dependent diabetes. The progenitors of these surrogate pancreatic cells have no reprogramming genes integrated into their genomes, differentiate to the pancreatic lineage pursuant to a protocol that employs only defined reagents, and are substantially unable to differentiate to the mesodermal lineage.

  • Publication number: 20160320409
    Abstract: The present invention relates to new and/or improved methods of identification and selection of cardiomyocytes from human embryonic stem (hES) cells. The method further comprises isolating the selected cardiomyocyte population. There is also provided method for the screening for cardiovascular compounds comprising subjecting the said cardiomyocyte population to test compound/s, and observing and/or interpreting a response of the cardiomyocytes to the test compound.

  • Patent number: 6448030
    Abstract: A method for measuring both the anti-migratory and cytotoxic effects of anticancer drugs on cancer tissues measuring the chemosensitivity of human biopsies to therapeutic drugs. Single cell suspension preparations of biopsy tissue is exposed to anticancer drugs and introduced into the first chamber of a migration plate separated from a second chamber by a porous membrane opaque to radiation. A migration stimulus is added to the second chamber. Migrated cells on the side of the membrane facing the second chamber are labeled with a live-cell fluorescent indicator. Non-migrated cells on the side of the membrane facing the first chamber are labeled with a fluorescent indicator of cell death. The emitted fluorescence of both the migrated cells and the non-viable cells is quantified in a fluorescence plate reader. The comparative intensity of fluorescence is an indicator of the susceptibility of the cells to the cytotoxic properties of the drug.
