[Effect of connective tissues underlying precancerous lesions combined with epithelia separated from normal mucosa].
The connective tissues underlying the precancerous changes of the epithelia were separated and combined with the epithelia which were separated from the normal mucosa. The combinations were transplanted in nude mice. Specimens were taken at 6 and 10 weeks after transplantation and routinely processed for microscopic examination. The results show that the connective tissue underlying epithelial dysplasia may induce the normal epithelium undergoing epithelial dysplasia changes. The experiment demonstrates the etiological importance of the connective tissue in the development of cancer, and may be applied clinically in the treatment of precancerous lesions.
