LepR+Runx2-GFPlow cells differentiate into osteoblasts through multilayered cell formation in response to PTH-induced anabolic effects. (AF) Z-stack confocal images of thick bone sections of 6 week-old LepR-Cre/Tomato/Runx2-GFP mice (A and B), tamoxifen-administered iOsx/Tomato/Runx2-GFP mice (C and D), and tamoxifen-administered iOsx/Tomato/Col1(2.3)-GFP mice (E and F) with vehicle (A,C and E) and hPTH(1–34) (B,D and F) intermittent treatment. Arrows: LepR-Cre-derived Tomato+(LepR/Tomato+)Runx2-GFP+ cells (A and B), iOsx/Tomato+Runx2-GFP+ cells (D) and iOsx/Tomato+Col1(2.3)-GFP+ cells (F). Arrowheads: iOsx/TomatoRunx2-GFP+ cells (C and D) and iOsx/Tomato+Col1(2.3)-GFP cells (F). *: Bone-lining mature osteoblasts. Nuclei were visualized with To-PRO-3 (blue).
