Abstract
Leiomyosarcoma (LMS) is an aggressive mesenchymal malignancy, which originates from the smooth muscle cells or from the precursor mesenchymal stem cells that potentially differentiate into smooth muscle cells. LMS is one of the most common sarcomas. LMS has genomic instability, reflecting complex and unbalanced karyotypes, and the cytogenetic and molecular changes in LMS are not consistent. The standard treatment of the primary LMS is complete resection, and the metastasis is often observed even after curative surgery. Patient-derived cancer models are a key bioresource to develop a novel therapy, and we aimed to establish and characterize a novel cell line for LMS. We established a cell line from tumor tissues of the patient with LMS and named it NCC-LMS3-C1. We maintained NCC-LMS3-C1 cells for 12 months and passed them more than 30 times. Genome-wide copy number analysis demonstrated that NCC-LMS3-C1 cells harbored genetic abnormalities. NCC-LMS3-C1 cells exhibited aggressive phenotypes such as continuous growth, spheroid formation, and invasion in the tissue culture condition, which may reflect the clinical behaviors of LMS. We performed a drug screening using NCC-LMS3-C1 cells and found that four anti-cancer agents, such as bortezomib, dasatinib, mitoxantrone, and romidepsin, had remarkable anti-proliferative effects on NCC-LMS3-C1 cells. We conclude that NCC-LMS3-C1 cells will be a useful resource for the study of LMS.

Abstract
Myxofibrosarcoma (MFS) is a rare and aggressive mesenchymal malignancy characterized by complex karyotypes with heterogeneous clinical features. The standard treatment for primary MFS is curative resection; however, the utility of systemic chemotherapy and radiotherapy has not been established. Although patient-derived cancer cell lines are a key bioresource for developing novel therapies, the number of MFS cell lines available from public cell banks is limited by the rarity of the disease, and large-scale drug screening has not yet been performed. To address this issue, we aimed to establish and characterize a novel MFS cell line. We successfully established a cell line, NCC-MFS6-C1, which harbors genetic abnormalities common in MFS and exhibits aggressive phenotypes such as continuous growth, spheroid formation, and invasion in tissue culture conditions. We performed drug screening using NCC-MFS6-C1 along with five MFS cell lines established in our laboratory and clarified the response spectrum of 214 existing anticancer agents. We found that two anticancer agents, gemcitabine and romidepsin, showed considerable antiproliferative effects, and these observations were concordant with the findings of our previous report, in which these agents attenuated the proliferation of five previously reported MFS cell lines. We conclude that NCC-MFS6-C1 is a useful resource for studying MFS.

Abstract
Ewing sarcoma (ES) is a small round cell sarcoma that is characterized by the unique gene translocation EWSR1-FLI1. It is the second most common primary bone and soft tissue malignancy in children and adolescents. It constitutes 10-15% of all bone sarcomas and is highly aggressive and rapidly recurring. Although intensive treatments have improved the clinical outcome of ES patients, 20-25% of them exhibit metastases during diagnosis. Thus, the prognoses of these patients remain poor. Cell lines are pivotal resources to investigate the molecular background of disease progression and to develop novel therapeutic modalities. In this study, we established and characterized a novel ES cell line, NCC-ES2-C1. The presence of the EWSR1-FLI1 fusion gene in these cells was confirmed in the NCC-ES2-C1 cells. Furthermore, these cells exhibited constant proliferation, and invasion, but did not form tumors in mice. We screened the anti-tumor effects of 214 anti-cancer drugs in NCC-ES2-C1 cells and found that the drugs which effectively reduced the proliferation of NCC-ES2-C1 cells. We concluded that NCC-ES2-C1 cells are a useful resource to study functions of the EWSR1-FLI1 fusion gene, investigate phenotypic changes caused by genes and proteins, and evaluate the anti-tumor effects of novel drugs.

Abstract
BACKGROUND The establishment of patient-derived models for pancreatic ductal adenocarcinoma (PDAC) using conventional methods has been fraught with low success rate, mainly because of the small number of tumour cells and dense fibrotic stroma. Here, we sought to establish patient-derived model of PDAC and perform genetic analysis with responses to anticancer drug by using the conditionally reprogrammed cell (CRC) methodology. METHODS We performed in vitro and in vivo tumourigenicity assays and analysed histological characteristics by immunostaining. We investigated genetic profiles including mutation patterns and copy number variations using targeted deep sequencing and copy-number analyses. We assessed the responses of cultured CRCs to the available clinical anticancer drugs based on patient responsiveness. FINDINGS We established a total of 28 CRCs from patients. Of the 28 samples, 27 showed KRAS mutations in codon 12/13 or codon 61. We found that somatic mutations were shared in the primary-CRC pairs and shared mutations included key oncogenic mutations such as KRAS (9 pairs), TP53 (8 pairs), and SMAD4 (3 pairs). Overall, CRCs preserved the genetic characteristics of primary tumours with high concordance, with additional confirmation of low-AF NPM1 mutation in CRC (35 shared mutations out of 36 total, concordance rate=97.2%). CRCs of the responder group were more sensitive to anticancer agents than those of the non-responder group (P < 0.001). INTERPRETATION These results show that a pancreatic cancer cell line model can be efficiently established using the CRC methodology, to better support a personalized therapeutic approach for pancreatic cancer patients.

Abstract
Leiomyosarcoma (LMS) is a rare and aggressive mesenchymal malignancy, derived from smooth muscle cells or precursor mesenchymal stem cells for this tissue type. LMS has highly complex and unstable karyotypes, and the clinical outcomes in patients with LMS remain dismal as evidenced by the 5-year-survival of 64%. Novel therapeutic approaches are required to improve its clinical outcomes. Patient-derived cancer cell lines are indispensable as a tool to study the molecular mechanisms underlying clinical behaviors of tumor cells such as resistance to treatments, metastasis, and recurrence. However, only a limited number of LMS cell lines are publicly available, probably because of the rarity of patients with LMS, and a paucity of cell lines hinders the research on LMS. This study aimed to develop a patient-derived LMS cell line. We successfully established a cell line from the primary tumor tissue of a 90-year-old female patient with pleomorphic LMS, which we named NCC-LMS2-C1. NCC-LMS2-C1 cells were maintained as a monolayer culture for over 29 passages spanning 10 months. NCC-LMS2-C1 cells exhibited continuous growth, the ability to form spheroid, and invasion capability. We screened 213 anti-cancer drugs to find those that have anti-proliferation effects on NCC-LMS2-C1 cells, and identified a histone deacetylase inhibitor, romidepsin. In conclusion, we have established a novel LMS cell line, NCC-LMS2-C1, which will be a useful resource to study the mechanisms of LMS progression and perform high-throughput screening for anti-cancer drug discovery.

Abstract
Spindle-cell/sclerosing rhabdomyosarcoma (ssRMS) is a rare subtype of rhabdomyosarcoma, characterized by unique pathological features. Although distinctive molecular backgrounds such as frequent mutations in MyoD1 have been reported, optimized therapy has not been fully developed, and further investigations are required. Patient-derived cancer models are critical tools for basic and pre-clinical studies. However, there is no model for ssRMS. Thus, this study aimed to develop a novel cell line from the tumor tissue of a patient with ssRMS. Using surgically resected tissue, we successfully established this cell line, named NCC-ssRMS1-C1. These cells exhibited spindle-shape morphology, consistent with the pathological observations of the original tumor tissue. Genetic studies demonstrated that NCC-ssRMS1-C1 cells retained original copy number alterations and the typical point mutation in MyoD1. Malignant phenotypes such as proliferation, spheroid formation, and invasion were confirmed in vitro by studying NCC-ssRMS1-C1 cells. Upon screening an anti-cancer agent library, sensitivity to conventional chemotherapeutic agents such as actinomycin D was revealed. We conclude that the NCC-ssRMS1-C1 cell line will be a useful resource for basic and pre-clinical studies.

Abstract
Extraskeletal osteosarcoma (ESOS) is a rare mesenchymal malignancy producing osteoid and bone in soft tissue without skeletal attachment. ESOS exhibits chemoresistance and poor prognosis, and is distinct from osseous osteosarcoma. The biological characteristics of ESOS are not fully understood, and patient-derived cell lines of ESOS are not available from public cell banks. Here, we established a novel cell line of ESOS and characterized its genetic and biological characteristics as well as examined its response to anti-cancer reagents. The cell line was established using tumor tissue from a 58-year-old female patient with ESOS, and named as NCC-ESOS1-C1. Phenotypes relevant to malignancy such as proliferation and invasion were examined in vitro, and genetic features were evaluated using the NCC Oncopanel assay. The response to inhibitors was monitored by screening of an anti-cancer reagent library. The cells constantly proliferated, showing spheroid formation and invasion capabilities. The NCC Oncopanel revealed the presence of actionable mutations in PIK3CA. Library screening revealed the presence of anti-cancer reagents with significant anti-proliferative effects on NCC-ESOS1-C1 at a low concentration. In conclusion, we established and characterized a novel ESOS cell line, NCC-ESOS1-C1. This cell line will be a useful resource for basic research and preclinical studies.
