Conversely, in tumors that progressed under treatment, ancestors of subclones dominating later in disease are present already at diagnosis. Chemotherapy treated xenografts and cell culture models replicate these two contrasting scenarios and show branching evolution to be a constant feature of proliferating NB cells.

microenvironment provides indispensable factors to sustain blood production throughout life. It is also a hotspot for the progression of hematologic disorders and the most frequent site of solid tumor metastasis. Preclinical research relies on xenograft mouse models, but these models preclude the human-specific functional interactions of stem cells with their bone marrow microenvironment. Instead, human mesenchymal cells can be exploited for the in vivo engineering of humanized niches, which confer robust engraftment of human healthy and malignant blood samples. However, mesenchymal cells are associated with major reproducibility issues in tissue formation. Here, we report the fast and standardized generation of human mini-bones by a custom-designed human mesenchymal cell line. These resulting humanized ossicles (hOss) consist of fully mature bone and bone marrow structures hosting a human mesenchymal niche with retained stem cell properties. As compared to mouse bones, we demonstrate superior engraftment of human cord blood hematopoietic cells and primary acute myeloid leukemia samples and also validate hOss as a metastatic site for breast cancer cells. We further report the engraftment of neuroblastoma patient-derived xenograft cells in a humanized model, recapitulating clinically described osteolytic lesions. Collectively, our human mini-bones constitute a powerful preclinical platform to model bone-developing tumors using patient-derived materials.", "doi": "10.1126/scitranslmed.abm6391", "pmid": "36223446", "labels": {"Clinical Genomics Lund": "Service", "Clinical Genomics": "Service"}, "xrefs": [], "notes": [], "created": "2022-11-29T07:57:46.468Z", "modified": "2023-02-20T13:52:55.809Z"}, {"entity": "publication", "iuid": "93a54b75e2294c589b968a9de83166e9", "links": {"self": {"href": "https://publications.scilifelab.se/publication/93a54b75e2294c589b968a9de83166e9.json"}, "display": {"href": "https://publications.scilifelab.se/publication/93a54b75e2294c589b968a9de83166e9"}}, "title": "Therapeutic targeting of KSP in preclinical models of high-risk neuroblastoma.", "authors": [{"family": "Hansson", "given": "Karin", "initials": "K", "orcid": "0000-0002-6993-7673", "researcher": {"href": "https://publications.scilifelab.se/researcher/1c0c991068644f61b10c986deff8fb7f.json"}}, {"family": "Radke", "given": "Katarzyna", "initials": "K", "orcid": "0000-0002-4460-0812", "researcher": {"href": "https://publications.scilifelab.se/researcher/ad483c946ce244fa898cadb6238e970d.json"}}, {"family": "Aaltonen", "given": "Kristina", "initials": "K", "orcid": "0000-0001-5104-735X", "researcher": {"href": "https://publications.scilifelab.se/researcher/68a63e2719d246a99fc51e8e3ed05cee.json"}}, {"family": "Saarela", "given": "Jani", "initials": "J", "orcid": "0000-0001-7306-7175", "researcher": {"href": "https://publications.scilifelab.se/researcher/c5febb7d8bc04ecb9664e3be19f4bb37.json"}}, {"family": "Ma\u00f1as", "given": "Adriana", "initials": "A", "orcid": "0000-0002-6955-1754", "researcher": {"href": "https://publications.scilifelab.se/researcher/7220571c605044f980abf2933374aa1a.json"}}, {"family": "Sj\u00f6lund", "given": "Jonas", "initials": "J", "orcid": "0000-0002-6992-3415", "researcher": {"href": "https://publications.scilifelab.se/researcher/eccac6b320244409879d5bac740f5202.json"}}, {"family": "Smith", "given": "Emma M", "initials": "EM", "orcid": "0000-0003-0609-4864", "researcher": {"href": "https://publications.scilifelab.se/researcher/4b453bd8533f4359b50e71c5aafa3d2a.json"}}, {"family": "Pietras", "given": "Kristian", "initials": "K", "orcid": "0000-0001-6738-4705", "researcher": {"href": "https://publications.scilifelab.se/researcher/5be0a3ec07654822a91df964eab1d6e4.json"}}, {"family": "P\u00e5hlman", "given": "Sven", "initials": "S"}, {"family": "Wennerberg", "given": "Krister", "initials": "K", "orcid": "0000-0002-1352-4220", "researcher": {"href": "https://publications.scilifelab.se/researcher/8a447e220e144c63a907f9c824ccc9da.json"}}, {"family": "Gisselsson", "given": "David", "initials": "D"}, {"family": "Bexell", "given": "Daniel", "initials": "D", "orcid": "0000-0001-9426-9550", "researcher": {"href": "https://publications.scilifelab.se/researcher/dda650768a264d93a80f40da6cb8d7e1.json"}}], "type": "journal article", "published": "2020-09-23", "journal": {"title": "Sci Transl Med", "issn": "1946-6242", "volume": "12", "issue": "562", "issn-l": "1946-6234"}, "abstract": "Neuroblastoma is a childhood malignancy with often dismal prognosis; relapse is common despite intense treatment. Here, we used human tumor organoids representing multiple MYCN-amplified high-risk neuroblastomas to perform a high-throughput drug screen with approved or emerging oncology drugs. Tumor-selective effects were calculated using drug sensitivity scores. Several drugs with previously unreported anti-neuroblastoma effects were identified by stringent selection criteria. ARRY-520, an inhibitor of kinesin spindle protein (KSP), was among those causing reduced viability. High expression of the KSP-encoding gene KIF11 was associated with poor outcome in neuroblastoma. Genome-scale loss-of-function screens in hundreds of human cancer cell lines across 22 tumor types revealed that KIF11 is particularly important for neuroblastoma cell viability. KSP inhibition in neuroblastoma patient-derived xenograft (PDX) cells resulted in the formation of abnormal monoastral spindles, mitotic arrest, up-regulation of mitosis-associated genes, and apoptosis. In vivo, KSP inhibition caused regression of MYCN-amplified neuroblastoma PDX tumors. Furthermore, treatment of mice harboring orthotopic neuroblastoma PDX tumors resulted in increased survival. Our results suggested that KSP inhibition could be a promising treatment strategy in children with high-risk neuroblastoma.", "doi": "10.1126/scitranslmed.aba4434", "pmid": "32967973", "labels": {"Clinical Genomics Lund": "Service", "Clinical Genomics": "Service"}, "xrefs": [{"db": "pii", "key": "12/562/eaba4434"}], "notes": [], "created": "2021-11-24T07:56:38.972Z", "modified": "2021-11-24T07:56:39.291Z"}]}
