[Behavior of pulmonary parenchyma and the bronchi after subcutaneous graft in the rat].
Subcutaneous isografts of small bronchi and pulmonary tissue were carried out, on rats. - 4 1/2 days after implantation, the bronchial epithelium was dedifferentiated, with mitoses. Smooth muscle disappeared. Pulmonary parenchyma was elastic. Such a state persisted until the 7th day. - 10 days after grafting, some bronchial cells had recovered short cilia. - After 2 weeks, the bronchial epithelium was perfectly redifferentiated: it showed goblet cells intermixed with columnar ciliated cells. Smooth muscle was not apparent. Some islets of elastic alveoli remained. - A similar state persisted for a further 8 weeks after transplantation, but the bronchial lumen appeared as a distended retention cyst with slightly flattened epithelium.
