Establishment and characterization of a novel patient-derived cell line from conventional central grade 3 chondrosarcoma, NCC-CS1-C1.

Chondrosarcoma (CS) is a malignant tumor that produces cartilaginous matrix and is the second most common primary bone sarcoma. CS encompasses a range of histological subtypes, with high-grade conventional central CS being particularly rare, occurring at a rate of 1.81 cases per 1 million person-years.

Establishment and characterization of NCC-GCTB14-C1 and NCC-GCTB15-C1: two novel patient-derived cell lines of giant cell tumor of bone.

Giant cell tumor of bone (GCTB) is a rare bone tumor that is genetically characterized by a unique mutation in the H3-3A gene. Curative surgical resection is the standard treatment. Unfortunately, a considerable proportion of patients with GCTB have local recurrence and pulmonary metastasis after surgical treatment, and current chemotherapy treatments have shown non-effective.
