We investigated effect of microgravity environment during spaceflight on postnatal development of the rheological properties of the aorta in rats.
The neonate rats were randomly divided at 7 days of age into the spaceflight, asynchronous ground control, and vivarium control groups (8 pups for one dam).
The spaceflight group rats at 9 days of age were exposed to microgravity environment for 16 days.
A longitudinal wall strip of the proximal descending thoracic aorta was subjected to stress-strain and stress-relaxation tests.
Wall tensile force was significantly smaller in the spaceflight group than in the two control groups, whereas there were no significant differences in wall stress or incremental elastic modulus at each strain among the three groups.
Wall thickness and number of smooth muscle fibers were significantly smaller in the spaceflight group than in the two control groups, but there were no significant differences in amounts of either the elastin or collagen fibers among the three groups.
The decreased thickness was mainly caused by the decreased number of smooth muscle cells.
Plastic deformation was observed only in the spaceflight group in the stress-strain test.
A microgravity environment during spaceflight could affect postnatal development of the morphological and rheological properties of the aorta.
