Abstract

A neuroblastoma × glioma hybrid cell line with well-developed neural properties was found that has high-affinity morphine receptors. The average cell contains approximately 3 × 106 receptors. In contrast, parent cells and other neuroblastoma or hybrid cell lines tested had few or no morphine receptors.
