Abstract EN
Low birth weight is associated with reduced bone mass and density in adult life.
However, effects of maternal hypoxia (MH) on offspring bone development are not known.
Objective.
The current study investigated the effects of fetal growth restriction induced by MH during the last half of gestation on bone structure and volume in the offspring of the fetus near term and the pup in adolescence.
Methods.
During 35–62-day gestation (term, 69d), guinea pigs were housed in room air (21% O2; control) or 12% O2 (MH).
Offspring femur and tibia were collected at 62d gestation and 120d after birth.
Results.
MH decreased fetal birth weight but did not affect osteogenic potential pools in the fetal bone marrow.
Histological analysis showed no effects of MH on tibial growth plate thickness in either fetal or postnatal offspring, although there was increased VEGF mRNA expression in the growth plate of postnatal offspring.
MH did not change primary spongiosa height but lowered collagen-1 mRNA expression in postnatal offspring.
There was increased mRNA expression of adipogenesis-related gene (FABP4) in bone from the MH postnatal offspring.
Conclusion.
MH during late gestation did not change the pool of osteogenic cells before birth or growth plate heights before and after birth.
However, MH reduced expression of bone formation marker (collagen-1) and increased expression of fat formation marker (FABP4) in postnatal offspring bone.
