Summary H3-thymidine labeled lymphocytes from thymus and lymph nodes of donor rats were washed and injected in to the intestine of recipient rats on the 11th and 19th day of gestation; subsequent labeling of maternal and embryonal cells was studied autoradiographically 24 hours after injection. In 12-day embryos, numerous stem cells or hemocytoblasts were labeled frequently intensely. In 20-day embryos, stem cells or hemocytoblasts scattered throughout the liver were often labeled. In other fetal tissues at this stage, cells in thymus, spleen, mesenteric lymph node and intestine were labeled but scarcely and weakly. In mothers, labeling in lymphoid tissues was scarce but definite, in thymus, mesenteric lymph node and spleen. These results suggest that nuclear materials from lymphocytes emigrated into the intestinal canal of the mother could be reutilized by maternal and embryonal cells.
