[Organ culture of human embryonic lung tissue]

Results of morphological study of organotypical cultures of the embryonal pulmonary tissue of 22-24 weeks human fetuses showed that for 30 experimental days they passed the period of adaptation, of the optimal growth and differentiation and gradual death. These periods were also characteristic of organic cultures of the embryonal pulmonary tissue of rodents. However, the processes of growth and differentiation in the corresponding human cultures were seen chiefly in the connective, and in rodents - in the epithelial tissue.
