[Structural and functional reorganization in epithelia of soft palate and bronchi cultured in vivo using F.M. Lazarenko method: the role of neuroendocrine factors].

To define the range of histio- and organotypical capacities of rat soft palatine and bronchial epithelia, and to elucidate the nature of the effect of neuroendocrine factors of hypothalamic paraventricular factors upon them, the experiments were conducted by co-culturing mucosal fragments of oral and pharyngeal surfaces of soft palate and bronchi with the paraventricular nuclei-containing hypothalamic fragments using in vivo F.M. Lazarenko method. Soft palatine and bronchial epithelia were found to have similar histoblastic properties. The stimulating effect of hypothalamic factors, released paraventricular nuclei, on the processes of regeneration of epithelia and of connective tissue was noted.
