Suppressor cells in the embryonic thymus mediate allograft tolerance.
Thymus cells from non-immunized young chickens suppress the allograft rejection in lightly irradiated syngeneic or allogeneic recipients and mediate longlasting skingraft survival in a significant proportion of recipients across a strong histocompatibility difference. Suppressive activity of this kind is already found in the embryonic thymus and is therefore believed to mediate also self tolerance and neonatal allograft tolerance.
