The cellular mechanism for the formation of lamellar bodies in type-II pneumocytes in rat lungs]

Pneumocyte type II cells from lungs of native rats and of rats that inspired a hypoxic mixture of gases were investigated by transmission electron microscopy. In cells of experimental rats, membrane structures were found that well compare with lamellar bodies. Experimental results and analysis of literature allowed to put forward a hypothesis about the cell mechanism of formation of lamellar bodies from the spiral twisted membranes of the endoplasmic reticulum.
