  • Patent number: 9977012
    Abstract: A method for cryopreservation of adherent cells attached to a substrate and a method for identifying one or more extracellular matrix (ECM) components and/or matricellular proteins that improves viability and retention of the cryopreserved cells on the substrate. The method for cryopreservation includes treating a substrate with at least one ECM component and/or adding at least one matricellular protein to the substrate or cell culture media, plating the cells on the treated substrate, and cryopreserving the cells. One or more ECM components and/or matricellular proteins that improves cell viability and retention can be identified by evaluating the cells that have been thawed from the cryopreservation temperature to determine cell viability and retention.

  • Patent number: 9834756
    Abstract: Methods of isolating cellular products, such as pancreatic islets, may be used in diabetes research and therapeutic transplantation. The methods may involve providing a donor tissue having desired cells and undesired cells, perfusing the donor tissue with a perfusion solution, developing edema during perfusion of the donor tissue to form a swelled tissue, and separating the desired cells from undesired cellular material to obtain a cellular product. The methods may also include disrupting the tissue, and separating the desired cells from undesired cellular material to obtain the cellular product. The methods may result in an increased yield of cellular product that retains sufficient functional integrity to be useful as a transplantation resource.
