Abstract: The present disclosure provides a model of human fibrolamellar hepatocellular carcinoma (FL-HCC) cells maintained as a transplantable tumor line in a host and a method to establish a transplantable human FL-HCC tumor line. Methods of ex vivo cultures of the FL-HCC are provided. Methods of diagnosing and treating FL-HCC tumors are also provided.

Abstract: Compositions and methods of transplanting cells by grafting strategies into solid organs (especially internal organs) are provided. These methods and compositions can be used to repair diseased organs or to establish models of disease states in experimental hosts. The method involves attachment onto the surface of a tissue or organ, a patch graft, a “bandaid-like” covering, containing epithelial cells with supporting early lineage stage mesenchymal cells. The cells are incorporated into soft gel-forming biomaterials prepared under serum-free, defined conditions comprised of nutrients, lipids, vitamins, and regulatory signals that collectively support stemness of the donor cells. The graft is covered with a biodegradable, biocompatible, bioresorbable backing used to affix the graft to the target site. The cells in the graft migrate into and throughout the tissue such that within a couple of weeks they are uniformly dispersed within the recipient (host) tissue.

Abstract: Human biliary tree stem/progenitors (hBTSCs) are being used for cell therapies of patients with liver cirrhosis. A cryopreservation method was established to optimize sourcing of hBTSCs for these clinical programs and that comprises serum-free Kubota's Medium (KM) supplemented with 10% dimethyl sulfoxide (DMSO), ˜3% recombinant human albumin and 0.1% hyaluronans. Cryopreserved versus freshly isolated hBTSCs were similar in vitro with respect to self-replication, stemness traits, and multipotency. They were able to differentiate to functional hepatocytes, cholangiocytes or pancreatic islets, yielding similar levels of secretion of albumin or of glucose-inducible levels of insulin. Cryopreserved versus freshly isolated hBTSCs were equally able to engraft into immunocompromised mice yielding cells with human-specific gene expression and human albumin levels in murine serum that were higher for cryopreserved than for freshly isolated hBTSCs.

Abstract: Compositions and methods of transplanting cells by grafting strategies into solid organs (especially internal organs) are provided. These methods and compositions can be used to repair diseased organs or to establish models of disease states in experimental hosts. The method involves attachment onto the surface of a tissue or organ, a patch graft, containing the donor cells. The donor cells may be a mixture of stem cells/progenitors with supporting early lineage stage mesenchymal cells. The patch graft promotes migration of the donor cells into the host organ and supports the successful integration of donor cells with host cells to repair the diseased organ.

Abstract: Described herein are in vitro cancer metastasis models that recapitulate biological facets of organ specificity as indicated by the behavior of human colorectal cancer cells when on substrata of liver and lung biomatrix scaffolds, organ-specific matrix extracts generated by novel decellularization strategies. Tumor cells spontaneously formed colonies that mimicked in vivo metastatic lesions in terms of histology, biology and genetic and other phenotypic traits. Not to be bound by theory, it is postulated that responses of tumors to radiation or chemotherapeutic agents proved dependent on the matrix substratum used; thus, thus the scaffolds are believed to provide a powerful tool for cancer research and diagnosis.
