title: Effect of mouse submaxillary gland and NGF preparations on competent chick ectodermin vitro, studied by the immunofluorescence method.
abstract: The submaxillary gland of the male mouse, but not the female, was shown to act strongly neuralizing on competent chick ectoderm, recorded as frequency of neural antigen producing cultures. NGF preparations from mouse submaxillary gland were shown to cause a high frequency of neural antigen producing cultures. The effect of the NGF preparations diminished with time and ceased after storage at -90° C for 17 days. The possible role of NGF in the present system is discussed; but the possibility could not be excluded that factors other than NGF present in the submaxillary gland and the NGF preparations cause the competent ectoderm to neuralize.
