چکیده انگلیسی


- Artery and vein identity is acquired in a stepwise manner in the neonate mouse retina.
- Arterial gene and protein expression patterns were evaluated during retinal development.
- Venous gene and protein expression patterns were evaluated during retinal development.

The murine retina has become an ideal model to study blood vessel formation. Blood vessels in the retina undergo various processes, including remodeling and differentiation, to form a stereotypical network that consists of precisely patterned arteries and veins. This model presents a powerful tool for understanding many different aspects of angiogenesis including artery and vein (AV) cell fate acquisition and differentiation. However, characterization of AV differentiation has been largely unexplored in the mouse retinal model. In this study, we describe the expression of previously established AV markers and assess arteriovenous acquisition and identity in the murine neonatal retina. Using in situ hybridization and immunofluorescent antibody staining techniques, we analyzed numerous AV differentiation markers such as EphB4-EphrinB2 and members of the Notch pathway. We find that at postnatal day 3 (P3), when blood vessels are beginning to populate the retina, AV identity is not immediately established. However, by P5 expression of many molecular identifiers of arteries and veins become restricted to their respective vessel types. This molecular distinction is more obvious at P7 and remains unchanged through P9. Overall, these studies indicate that, similar to the embryo, acquisition of AV identity occurs in a step-wise process and is largely established by P7 during retina development.
