Negative impact of hyperglycaemia on mouse alveolar development.

ABSTRACT: Diabetes mellitus in pregnancy has been known to affect the embryonic development of various systems, including cardiovascular and nervous systems. However, whether this disease could have a negative impact on embryonic respiratory system remains controversial. In this study, we demonstrated that pregestational diabetes mellitus (PGDM)-induced defects in lung development in mice are mainly characterized by the changes in the morphological structure of the lung. Immunostaining and Western blotting showed that proliferation increased and apoptosis decreased in PGDM. Hyperglycaemia caused pulmonary tissue fibrationas manifested by an increase in Masson staining and decorin expression in PGDM lungs, and the immunofluorescent pro-SPC+ type II pulmonary epithelial cell number was decreased.
