Summary

Diacylglycerol (DG) and triacylglycerol (TG) levels in rat lung tissue were determined from day 17 of gestation to day 10 post partum and studied in parallel with ultrastructural differentiation. The DG level, although rather low at all measured stages, rose significantly between days 17 and 19 and at birth. TG level increased steadily during the whole studied period and especially between days 17 and 19 and at birth. In DG as well as in TG, saturated fatty acids were predominant. The rising of TG levels paralleled the appearance and accumulation of lipid vacuoles in mesodermal cells lying in contact with type II cells. The possible role of these cells is discussed.
