Histochemical localization of succinate dehydrogenase in intracerebral mouse submandibular gland transplants.
Histochemical localization of succinate dehydrogenase in developing intracerebral auto- and homotransplants of the mouse submandibular gland was investigated in the course of a 5-month period after transplantation. Eight weeks after grafting, the enzyme pattern in the parenchyma of homotransplants was comparable with the histochemical picture of a fully mature submandibular gland in situ. At this time, numerous acini showed a weak activity, very numerous striated ducts a strong activity, and less frequent developing convoluted granular tubules slightly weaker activity, than in the striated ducts. Beginning histochemical differentiation of convoluted granular tubules was noted only in homotransplants, located in the brain of male recipients. On the other hand, only a weak activity in the cytoplasm of non-differentiated duct--like structures of some autotransplants was seen. Homotransplants of non-differentiated submandibular gland of newborn donors were found to be a more suitable transplantation object capable of postnatal development of gland parenchyma than autografts of fully differentiated gland of adult animals that did not enter the cytodifferentiation stage.
