The reverse transforming effects of nerve growth factor on five human neurogenic tumor cell lines: in vitro results.
The role of nerve growth factor (NGF) in the development, maintenance and regeneration of the mammalian sensory and sympathetic nervous systems has been well characterized, as has the ability of NGF to induce a variety of neoplastic cell lines of neuroecto-dermal (neurogenic) origin to differentiate. The ability to stimulate neoplastic cells of neurogenic origin to differentiate suggests that NGF may prove useful as a reverse transforming agent for the treatment of neurogenic tumors. Five human neurogenic tumor cell lines were evaluated for their response to NGF in vitro to determine whether the NGF is capable of inducing changes consistent with a reverse transforming response. Results indicate that NGF was able to reverse some of the transformed properties of these tumor cell lines, as NGF treatment stimulated neoplastic cells to develop a more differentiated phenotype, diminished or arrested growth, and induced changes that were persistent.
