The Influence of Hypoxia during Different Pregnancy Stages on Cardiac Collagen Accumulation in the Adult Offspring

We evaluated whether the timing of maternal hypoxia during pregnancy influenced cardiac extracellular matrix accumulation in the adult offspring. Rats in different periods of pregnancy were assigned to maternal hypoxia or control groups. Maternal hypoxia from day 3 to 21 of pregnancy or day 9 to 21...
