摘要:: A nerve cell line designated NC-HIMT was established from a HIMT cell line derived from a benign ovarian, three germ layer immature teratoma removed from a 21-year-old Japanese female. The HIMT cells were elongated, ellipsoid or spherical in shape, whose karyotype was on the high side of normal diploidy. Small amounts of retinoic acid enhanced differentiation and maturation of the HIMT cells into nervous tissue, and the NC-HIMT cell line was established by the colony isolating technique when the HIMT cell line was cultured in the presence of retinoic acid-supplemented medium. After establishment, the NC-HIMT cell line was cultured and maintained in retinoic acid-free growth medium. Even though these cells were cultured without retinoic acid, the phenotype of nerve cells remained and the cells were also maintained in a state of high normal diploidy. The nerve cells contacted each other with their long cell projections and formed networks. Immunocytochemical observations using anti-bovine NSE, alpha-internexin, neurofilament 200kD, peripherin and GFAP confirmed that the cells were either nerve cells or glia cells. These results assume that HIMT cells, which were derived from an immature teratoma, have progenitor and/or stem cells which can differentiate into nerve and/or glial cells.
