ngf-stimulated ( 'differentiated ' ) and unstimulated ( 'undifferentiated ' ) cells were studied by cytochemical techniques for the localization of the enzymes acid phosphatase ( acpase ) and thiamine pyrophosphatase ( tppase ) , and by a morphometric analysis of the distribution of endocytosed wheat-germ agglutinin labelled with horseradish peroxidase ( wga-hrp ) .
