  • Publication number: 20240026276
    Abstract: A method of providing sensing apparatus and a sensing method are disclosed. One aspect provides sensing apparatus comprising: a chamber configured to receive a biological sample at least part of a wall of the chamber comprising a printed circuit board substrate; the part of the wall comprising a printed circuit board substrate comprising an electrode configured to transmit or receive a signal to the biological sample, the electrode being coupleable to a sensing control unit located outside the chamber. The apparatus comprising a channel in communication with the chamber, the channel being dimensioned to allow at least a portion of the biological sample extend through the channel, the channel comprising a conductive surface configured to transmit or receive a signal to at least a portion of the biological cell sample extendable through the channel, the conductive channel surface being coupleable to the sensing control unit located outside the chamber.

  • Publication number: 20230137573
    Abstract: The present invention generally relates to pharmaceutical compositions containing a protease proenzyme and use thereof for treating cancer. The pharmaceutical compositions are directed to compositions comprising a protease proenzyme and an active agent, the composition being capable of providing a multi-functional approach for treating cancer. The pharmaceutical compositions are also directed to compositions comprising a first and a second protease proenzyme capable of activation at or near a surface of a tumour cell to enhance cell-to-cell adhesion of tumour cells, effect proteolysis of tumour cells, or induce tumour cell apoptosis, differentiation or immunorecognition, wherein the first protease proenzyme is chymotrypsinogen and the second protease proenzyme is trypsinogen. The pharmaceutical compositions are also directed to compositions comprising a first and second active agent each capable of inducing intracellular activity in tumour cells.

  • Patent number: 8815590
    Abstract: Described are methods for inducing differentiation of a human embryonic stem cell or a population of human embryonic stem cells toward a cell or population of cells characteristic of the definitive endoderm, the method comprising incubating the cell or population of cells with a GSK-3 inhibitor. Also described are methods for inducing differentiation of a cell or population of cells, characteristic of the definitive endoderm, towards a hepatocyte-like cell or a population of hepatocyte-like cells, and methods for inducing differentiation of a human embryonic stem cell or a population of human embryonic stem cells toward a hepatocyte-like cell or a population of hepatocyte-like cells. Further described are cells obtained by the methods and uses thereof in therapy and toxicity screening.
