[Mucociliary activity of free transplanted respiratory epithelium].
The function of free grafted respiratory epithelium was investigated in inbred rats. In nine of ten animals it could be shown that the respiratory epithelium not only regenerated as an epithelial surface lining but also regained mucociliary activity. The grafted epithelium was able to secrete mucus, which was equal in protein fragmentation to the secretion of normal nasal mucosa. The grafted respiratory epithelium showed normal ciliary function which could be demonstrated by recording the ciliary beat pattern present and by subsequent histological examination. Morphologically, a regular structure of ciliae (9 + 2) was found on the upper pole of the regenerated ciliated cells.
