Tonsillar Tissue Implants in Neonatally Thymectomized Mice

摘要

Palatine tonsils from 28- and 29-day fetal rabbits, and from 1-day-old rabbits were implanted into the abdominal cavities of 1-day-old mice thymectomized at birth. After 4 or 6 weeks the spleens of these mice showed restoration of follicular organization and repopulation by lymphocytes of thymus-dependent and perifollicular areas, as compared with thymectomized, non-implanted controls. These results clearly indicate functional similarities between palatine tonsillar tissue and thymic tissue.
