Abstract

Analysis of human tumor cells in vitro enhances the study of numerous neoplastic conditions. However, it has been difficult to establish long-term cultures of adenoma cells, especially those of neuroendocrine origin, because the endocrine cells survive only briefly in culture, and fibroblasts overgrow the culture dish in 1 or 2 weeks. We describe cells isolated from pituitary adenomas in two patients with multiple endocrine neoplasia type 1 in which cells with a mesenchymal phenotype evolved from pituitary tumor cells. It appears that these poorly differentiated cells arose from multipotent adenoma cells. This represents a path of cell differentiation not observed previously in humans and may help explain the diverse nature of the benign tumors in multiple endocrine neoplasia type 1.
