Abstract:
Mouse fetuses beginning from 13-day plug age and new borns from 1-dayto the adult stage were prepared for the study of acid and alkaline phosphatasesaccording to MacDonald's and Danielli's modified methods of Gomeri respective-ly. It was found that the distribution of acid and alkaline phosphatases in thedevelopment of vibrissae is essentially the same. The enzymes begin to increasein the condensed mesenchymal anlage of papilla and in the invaginating epidermisof 14th day fetus. The phosphatases in the papilla and then in the connectivetissue sheath keep their high concentration from the beginning of hair follicleformation to the adult stage, while those in the epidermal sheath are graduallydecreased and localized in the course of differentiation. The bulb has higheramount of enzymes than the distal region of the follicle throughout all the stagesstudied. The significance of distribution of the enzymes is discussed.
