Abstrakt: An antiserum to chicken soluble thymic factor (STF) was prepared in rabbits and absorbed with chicken thymocytes until it reacted only with thymic reticuloepithelial cells. When injected into 6-day-old embryonated eggs, this antiserum caused a severe depletion of small lymphocytes in the cortical region of the thymus which was filled with large undifferentiated cells. In addition, reticuloepithelial cells displayed a marked disruption of cytoplasmic elements. The percentage of thymic lymphocytes bearing the T antigen was greatly reduced. It is believed that a factor responsible for differentiation of stem cells into T cells has been inhibited. [ABSTRACT FROM AUTHOR]
