Mechanical stimulation enhances osteoblastogenesis by perinatal chondrocytes but not by adult skeletal progenitors. a–f show the results from 1-month-old mice, and g–l show the results from 3-month-old mice. Skeletal progenitors are marked by Tomato, and osteoblasts are marked by GFP. Mechanical stimulation (running) increased the number of Tomato+ osteoblasts in the GFP-labeled osteoblast pool in younger mice, while in older mice, the difference is not significant.
