Establishment and characterization of human neuroblastoma cell lines.
Three new tissue culture cell lines, CHP-100, CHP-126, and CHP-134, have been established from explant cultures of human neuroblastoma. The cell lines have been characterized with respect to morphology, chromosomes constitution, growth, neural enzyme content, and their ability to grow in nude mice. The cells grow as dense masses comprised of fibroblast-or neuroblast-like cells with small processes. The cell lines differ in their neural enzyme acitivity. The chromosomal content of the 3 cell lines is near diploid, and all are capable of forming tumors in nude mice. The morphological findings indicate that the cells in culture resemble those found in the tumor, and the enzyme activities are consistent with those of nervous tissue. This the morphological, biochemical, and tumorigenic properties confirm that the 3 cell lines are neoplastic cells of neural origin.
