Nerve growth factor receptors on cultured rat Schwann cells.

Neonatal rat Schwann cells were grown in tissue culture and assayed for NGF receptors with time in culture. NGF receptor levels on freshly prepared Schwann cells (day 0) were low but increased dramatically during the first week in culture. Characterization of 125I-NGF binding to resuspended cells grown for 4 d in culture revealed that binding was not saturable at high ligand concentrations (50-...

Nerve growth factor receptors on dissociated neurofibroma Schwann-like cells.

Neurofibromatosis is a disorder which predominantly involves cellular elements of peripheral neural sheaths. Little is known about the regulation of differentiation and proliferation of cells comprising neurofibromas. Because nerve growth factor-like activity may be present in neurofibromas and the cells comprising neurofibromas are neural crest derivatives, we have investigated whether nerve g...

Nerve growth factor receptors on human melanoma cells in culture.

Purified mouse nerve growth factor (NGF)radiolabeled with 125I was tested for its ability to bind to a variety of different cultured cells. NGF binds readily to human and hamster melanoma cells but does not bind to many other cell lines. The three cell lines with the highest number of NGF receptors were derived from metastatic melanomas. One of these lines, A875, was studied in detail and was s...

Nerve growth factor in rat glioma cells.

We have shown that rat glioma tumors contain a protein that crossreacts with antibody against mouse 2.5S nerve growth factor prepared in rabbit in microcomplement fixation assays and has analogous isoelectric points to all the hybrids of 2.5S nerve growth factor (a dimer). Partially purified protein preparations from gliomas cause chick dorsal root ganglia to extend neurites in the nerve growth...

Cultured human trabecular meshwork cells express functional growth factor receptors.

PURPOSE To compare the mRNA expression of growth factor receptors in cultured human trabecular meshwork (HTM) cells with ex vivo HTM tissues and to determine whether HTM cells generate a physiologic response after exposure to exogenous growth factors. METHODS The reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect the expression of various growth factor receptor...
