SPECIAL ISSUES DISEASE CONNECTIONS Influence of Hormones and Hormone Metabolites on the Growth of Schwann Cells Derived From Embryonic Stem Cells and on Tumor Cell Lines Expressing Variable Levels of Neurofibromin


Loss of neurofibromin, the protein product of the tumor suppressor gene neurofibromatosis type 1 (NF1), is associated with neurofibromas, composed largely of Schwann cells. The number and size of neurofibromas in NF1 patients have been shown to increase during pregnancy. A mouse embryonic stem cell (mESC) model was used, inwhichmESCswith varying levels of… (More)
