Prx1 expression is confined to the adult periosteum in the ulnar midshaft. Skeletally mature 16-week-old Prx1CreER-GFP;Rosa26tdTomato mice received a single dose of tamoxifen to induce tdTomato production and were sacrificed a week later. Recombined cells (red) were found in the periosteum (white arrows) of the ulna, but were absent from cortical bone, trabecular bone, muscle, and bone marrow. Micrographs were captured with a confocal microscope at 20X. Scale bar = 50 μm
