Description
Abstract
In order to obtain more information on the
development, morphology and function of the pores of
Kohn, the lungs of Wistar rats are studied during their
early postnatal period, up to 3 weeks of age, by scanning
and transmission electron microscopy.
The substantial development of the interalveolar
pores on days 14 and 21 coincides with the period of
septal rearrangement when secondary interalveolar
septa become lengthened and thinner. The high
frequency of transseptal type 11 pneumocytes from day 7
onwards, and their typical localization near the pores
of Kohn at this period of lung development especially
suggests that type 11 pneumocytes are engaged in the
formation of the pores of Kohn. During early lung
development, the pores of Kohn seem to serve as
passageways for alveolar macrophages.
