A new human cell line, HS-Os-1, derived from a case of osteoblastic osteosarcoma arising in the humerus of an 11-year-old girl was established. Light microscopically, HS-Os-1 cells growing in a monolayer (in vitro) were pleomorphic, intermingled with a few multinucleated giant ones, and positive with alkaline phosphatase reaction. In the transplanted tumors in athymic nude mice (in vivo), atypical spindle or polygonal cells densely proliferated with prominent osteoid formation and even calcification. HS-Os-1 cells, both in vitro and in vivo, were mostly positive for vimentin and a few for S-100 protein. Ultrastructurally, HS-Os-1 cells in vitro and in vivo also revealed essentially the same features as the eccentrically located, euchromatin-rich nuclei with prominent nucleoli, a lot of well-developed, irregularly-dilated rough endoplasmic reticula, polysomes and microfilaments in the cytoplasm. Namely, HS-Os-1 cells fully expressed and possessed morphological characteristics as osteoblastic nature during the cultivation and heterotransplantation. This cell line, therefore, proved to be extremely useful to search for human osteosarcomas.
