[Tracheal transplantation in inbred strains of rats.--IV. Histologic and histoautoradiographic findings in the epithelium (author's transl)].

In the first ten days after transplantation isogeneic and allogeneic tracheal transplants keep their epithelium, showing metaplasia as a sign of distinct regenerative activity in this time. In various degrees dependent on the constellation of experiments there are only signs of a weak chronic rejection. After more than 280 days again a stratified epithelium can be seen. In exeptional cases mucosa of second-set-transplants only show an obvious rejection reaction.
