Fig. 5From: Sexual dimorphism in reactive oxygen species production and a role for integrin α1β1 in estrogen receptor α and β expression in articular cartilageDigitally zoomed confocal microscopy images of chondrocytes from the lateral tibial plateaus of a female wild-type or itga1-null mice, and a male itga1-null mice. Images show ERα stained red, ERβ stained green, overlay of ERα and ERβ, or differential interference contrast (DIC). All nuclei counterstained blue with Hoechst. Note the presence of ERα and ERβ in the cytoplasm and/or nucleus, and colocalization of ERα and ERβ in the cytoplasm. Scale bar 2 μmBack to article page
