[Alkaline phosphatase in the differentiating receptor cells of the bull olfactory lining]

Alkaline phosphatase examined in the bull olfactory mucosa receptor cells using a cytochemical method for its activity is found to be a marker of neurogenesis and differentiation of the receptor cells. The enzyme localization is shown to change with the production of a receptor neuron dendrite and axon. The role alkaline phosphatase may play in the transmembrane and intracellular transport of substances and in microtubular structure polymerization during the cell differentiation is discussed.
